Virtual Host under MacOSX not working

I have setup a virtualhost for MacOSX Apache installation. These are my steps:   * edit /private/etc/apache2/httpd.conf removing comment from:              Include /private/etc/apache2/extra/httpd-vhosts.conf         * edit /private/etc/apache2/extra/httpd-vhosts.conf, added:               <VirtualHost *:80>     ServerName test.local     DocumentRoot "/Users/myusername/Sites/Test/public"     <Directory "/Users/myusername/Sites/Test/public">     Options Indexes FollowSymLinks Includes     AllowOverride All     Order allow,deny     Allow from all     </Directory>     </VirtualHost>        * edit /private/etc/hosts added              127.0.0.1 test.local        * Restart Apache But the VirtualHost does not work. To further isolate the problem, I check the same configuration with `MAMP` and the virtual host worked right, so the configuration files should be fine. What can be wrong?


SEO: Will Multiple Redirects (301, Permalink Plugin) affect ranking

I asked for help over at WordPress Answers StackExchange for doing a 301 Redirect for my website, which will involve a permalink structure change also. One of the suggested solutions was `301 Redirect` via `Apache (.htaccess)` and then use a plugin for internal redirects on the new site. The person who answered was not sure if using this two step approach will affect SEO and suggested I ask over here. So will doing a 301 Redirect and then having a plugin also redirect to the correct URL affect how Google indexes my new site, PageRank or any other SEO rankings?


Google Analytics E-Commerce doesn't track

My problem is with the tracking of my e-com. Conversion doesn't work. I did it like in the guide of google. The debug console doesn't show any problems. My code:                   <script type="text/javascript">            var _gaq = _gaq || [];       _gaq.push(['_setAccount', 'UA-XXXXXXXXX-1']);       _gaq.push(['_trackPageview']);          try{      _gaq.push(['_addTrans',           '<?php echo $id_eco ?>',            // transaction ID - required           'Bauer und Boecker',  // affiliation or store name          '<?php echo str_replace(",",".",$brutto_eco) ?>',           // total - required           '',            // tax           '',           // shipping           '',        // city           '',      // state or province           ''              // country         ]);                  // add item might be called for every item in the shopping cart        // where your ecommerce engine loops through each item in the cart and        // prints out _addItem for each       _gaq.push(['_addItem',          '<?php echo $id_eco ?>',           // transaction ID - necessary to associate item with transaction           '<?php echo $id_eco ?>',           // SKU/code - required           '<?php echo $bezeichnung_eco ?>',        // product name           '',   // category or variation           '<?php echo str_replace(",",".",$einzelpreis_eco) ?>',          // unit price - required           '<?php echo $menge_eco ?>'               // quantity - required        ]);          _gaq.push(['_trackTrans']); //submits transaction to the Analytics servers     } catch(err) {console.log(err);}            (function() {         var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;         ga.src = ('https:' == document.location.protocol ?

Conditional redirect based on referring source?

What liability concerns do advertising vendors raise, and how can I address them?

One of the websites I administer wants to provide free advertising in the form of direct links to vendors at an event they are running. Up until now, there has been no advertising whatsoever on the site (or any of our other sites). The site is for a for-profit business. The idea of implicit endorsement of any vendors we advertise has been raised, which brought up the question of what we need to do, if anything, to protect ourselves from any potential problems such endorsement might create. I know that many sites have clauses in their Terms of Service that state that (in a nutshell) they are not responsible for any problems or grievances between the visitors to the site and any vendor advertised or linked. Are there other steps that a website typically takes when considering advertising, such as getting the advertiser to provide some sort of certification that their ad will not violate any trademarks or copyrighted material?

I want to change the host account for Google app email?

I have a standard (free) Google app Email Service. In the last 5 months, we have been using this service. Our website was hosted at a third party web hosting company. Now I am planning to change my web hosting provider. I want to keep my domain at the previous hosting company. Can Google Apps allow this option of changing web hosting for the registered Domain in the Google App for Email Service?


How to follow the evolution of position in SERP in Google Webmaster Tools?

Is there a way to see the evolution in time of the position in search engine results? In Google Webmaster Tools I can see the different positions where my page was showed but is there a way to "sort it in time"? E.G. I see this: ![enter image description here](http://i.stack.imgur.com/L01m4.png) But is there a way to see chronologicaly the evolution? And what is the actual position as of now? "6 to 10", "2nd page" or "3rd page +"? PS: I mean directly in GWT (I don't want to buy any SEO software...)


Duplicating someone's content legitimately & writing HTML to support that

I want to add content from other blogs to my own (with the authors permission) to help build additional relevant content and support articles I've found useful that others have written. I'm looking into how to do this responsibly - ie, by giving the original content author a boost and not competing against them for search traffic which should go to their site. In order to keep my duplicate content out of search, and to hint to the search engines where the original content is to be found i've implemented:                      <meta name='robots' content='noindex, follow'>       <link rel='canonical' href='http://www.originalblog.com/original-post.html' />           Additionally, to boost the original article and to let readers know where it came from i'll be adding something like this:
       Article originally written by        Authors Name        and reproduced with permission.
              Read the original article here.
      All that remains is a way to 'officially' credit the original author in the HTML for the search spiders to see. Can anyone tell me a way to do this possibly using rel="author" (as far as I can see thats only good for my own original content), or perhaps it doesn't matter given that the reproduced pages will be kept out of search engines? Also, have I overlooked anything in the approach?


How does delicious.com avoid being sued for copyright infringement?

With the recent redesign of delicious.com, they've added a much more graphical home page. The site continues to be a service for people to bookmark and share websites they come across on the web. The delicious home is now made up of images taken from those linked sites. See for yourself at http://delicious.com I would like to know what in the law allows them to do this, considering the images represent the main content of the page, and they clearly do not own copyright to those images? I know there is some leeway given to search engines where it is considered fair use to use a small portion of the content if the aim is to lead people to the originating site. Does that apply here?


HTTPS on all pages where user is logged on

I know this is considered best practise to prevent cookie hijacking. I would like to adopt this approach, but ran across a problem on our forum where the users post images which either aren't posted with URL's over HTTPS or the url itself doesn't support HTTPS. This throws up a lot of ugly browser warnings. I see I have two options:   * Disable HTTPS for the forum   * Force all user posted content to start with `//` in the url so it selects the right protocol, if it doesn't support HTTPS so be it Do I have any other options? How do other sites deal with this?


How to change my website's appearance in a Facebook wall post?

When posting a website link in a Facebook wall post, Facebook fetches some content (title, text and image) from the website to show it to readers. Is there a way I can adjust / propose which content is used / preferred by Facebook? ![enter image description here](http://i.stack.imgur.com/itvcX.png) I found someone saying to use `<meta property="og:image" content="image.jpg">`, but this doesn't seem to have any effect. But maybe Facebook caches these results for a while?

Using RDFa with an image inside of an H1 tag

I come from a development background but just recently starting learning SEO along with RDFa. I am working on our companies new website where the designer is using our different divisions logos at the top of their respective pages. There currently are not any H1 tags. I know I need to add and H1 but the way the pages were designed the logos are where I would usually put an H1 heading. And if I added an H1 with text it would throw off the design. I also know that using images inside H1 isn't good practice even if I use the alt attribute. So my question is if I put H1 tags around the image, then use RDFa will Google find this acceptable or will this be penalized. Here is my code example:

      I defined my prefixes in the body tag and when I run my code through the validator at http://rdfa.info/play/ it seems like it would work, just not knowledgeable enough yet with SEO to know for sure.


What HTTP code to use when redirecting to random page

I have an URL `domain.com/random`, which will redirect to a random page. What would be the correct HTTP code for this? Plus, I'm inserting the link like this:               Show random profile      Spiders won't follow that link. Do I need to care about what HTTP code I send?


301 redirect + RewriteRule not working together?

I am using a 301 redirect to redirect a page to another page in the same website, which uses `RewriteRule` to hide the PHP variables in a friendly URL. My redirection code in .htaccess:               Redirect 301 /example/word1/word2/word3 http://www.example.com/word1/word2      As a result when I visit `/word1/word2/word3` it redirects me to the URL set by a previous RewriteRule which is `/word1/word2?var1=word1&var2=word2&var3=word3`. Where var1, var2, and var3 are the PHP variables that have for content word1, word2 and word3. I want the redirection to go just to `www.example.com/word1/word2`


Create friendly looking URL's with mod rewrite

I want to make the pages on my site more search engine friendly by turning the query strings into meaningful looking page names. For example I have a page that is this:               /search.php?c=18      I want it to look like this:               /doctors/MainCategoryName-18/      Sometimes there is a second query string so it would need to work with just one or both. For example:               /search.php?c=18&s=217      Should look like               /doctors/MainCategoryName-18/SubCatrogyrName-217/      Here's what I've tried so far but I can't get it to work.               RewriteRule ^search.php?c\=(.*)* /doctors/general-$1 [NC,R=301,L]     RewriteRule ^doctors/[^?/]*-(\d+)\ /search.php?c=$1&s=$2 [QSA      Thanks so much for your help,


.pro domain as a web designer/professional

I am looking at getting a .pro domain for my portfolio page as a web designer.

And also which certs would you recommend such as w3c or cwp?


Unable to print login-required images in IE

I have some images in a section of a site that require the user to be logged in in order to view. These images are served by a PHP script, which checks the user's login state and if valid, serves the binary data with the appropriate headers. This all works fine. The issue comes when a user tries to print one of these images. In Internet Explorer, when they go to print preview, they get the broken image box with a red cross in the corner instead of the actual file. This is also what gets printed. All other browsers can print the images without issue. I have some images elsewhere on the site that are also served via. PHP but these don't require a login. These print fine. The PHP-powered HTML pages on the site that require a login also print fine in IE. It's just login-required images. When the user hits 'print preview', this does not seem to result in additional HTTP request to the server for the file. However I do see an additional HTTP request a few seconds later that comes from the same IP (may or may not be related), This request includes no host header, no REQUEST_URI and no user agent. The 'please login' page sends an appropriate 403 header. I've also added a far-in-future expires header to the image response itself to ensure that browsers can serve/print the files from their own cache but this hasn't made any difference. Why can't IE print the images and what else can I do to investigate or fix the problem?


Why do some large companies use a different domain for sending emails?

I've received notifications and newsletters from Microsoft and Facebook in the past and noticed that both emails came not from an address such as something@facebook.com or something@microsoft.com. Not event something@somethingelse.microsoft.com but both had different domains such as : reply@email.microsoftemail.com and something@facebookmail.com **Why is this? Any particular advantage in doing so?** Other than not polluting the employees email software, I can't see.


How do I search server for all instances of a given database user?

We just migrated one of our machines to a new box. Same web host, but new IP and physical machine. I've found a lot of the databases are using a generic dbuser/pw combo. With the new server, I want to implement a more secure policy that all dbs need to have their own users, rather than a user that has global db privileges. Is there a way to search all the servers' web docs (Everything below /var/www/vhosts/) for references to a specific db username in any files? Is this a job for grep? Or is there a better solution?


Canonical tag on paginated pages?

I noticed that StackOverflow uses a `rel=canonical` tag on page 2+ of answers. For example, see http://stackoverflow.com/questions/6470651/creating-a-memory- leak-with-java?page=2&tab=votes#tab-top Notice they have a `rel=canonical` tag that points to http://stackoverflow.com/questions/6470651/creating-a-memory-leak-with-java As I recall, Maile Ohye at SMX Advanced said that you should NOT use a canonical tag in this way. The answers on page 2 are not duplicate content as to what's on page one, and duplicate content is the purpose of the canonical tag. Is this an appopriate use of the `rel=canonical` tag?


Is there a penalty for opposite of cloaking?

Let's assume I have 100 different web pages with original and good content. But I want to publish on these pages same advert content (text video flash pictures) If I decided to use ajax and jquery for loading that advertorial content after page load, would there be a penalty for that? I know using hidden div's and hidden text can cause penalties but what if it's the opposite?

no description when searching keyword in google

I am new with SEO, and i following a tutorial about meta tags... when i search my keyword in Google, I can only see the URL of my website but it has no description....                search in google: surebooked     ---------------------------------      but return only: surebooked.com/      There are no description in Google when I search my keyword. Does anyone have an idea about my situation?


How do you tell search engines not to index this page just yet, but maybe in the future?

The company I work for has a content management system that builds pages automatically for certain content. E.g., There is a page in our system that has the ability to show you information about any composer in our database, depending on the input parameters and what information we have on them. However, every now and then, there is a composer that hasn't got any information, thus the page renders a blank page. How can we tell Google not to index the page at that moment, but maybe sometime in the future? Because the content is auto-generated, we can't just block pages from being visible, as it information about that composer may pop up at any moment. **Edit** Please note that our CMS system that does the fetching is seriously complicated and deep. The content part of the page WILL return some sort of data, so running an `empty($content) ? xx : yy` as has been suggested is not a quick fix. If a composer does not exist, the system won't have a page for that the composer, if the composer does exist, the system will. When that composer's page is rendered, the system searches every type referring to composers, such as works, to create a dynamic page.

When to use canonical? Prepaid products of different values

I have a webshop for different kind of prepaid cards. Every kind of prepaid card is also available in a different value. The product page of those different values differ only in a title (NameOfProduct ValueOfProduct), image, and the value in the description. Do I have to use canonical for the different kind of values? Because the product pages doesn't seem to rank as well as the other pages in the search engines.


FAVICON: Favicon not showing up

I'm using a .png favicon file and it is not showing up on my site. Doing a grep, I see the following in home.htm which looks right for me(I have also confirmed it's in the HEAD section within home.htm):               home.htm: <link rel="shortcut icon" type="image/png" href="favicon.png">      The favicon.png file is in the same directory as the home.html file. Any suggestions are welcome! Thanks all. In case the file info is revealing for anyone, I'll attach it here: ![enter image description here](http://i.stack.imgur.com/csNOw.jpg)

cPanel Monthly Bandwidth Traffic - HTTP Traffic Extremely High

So I have a website/blog which I have hosted with a service which is offering me 2000mb of monthly bandwidth traffic. I recently have started getting a lot of traffic, or I suppose, enough to push me quite close to the cap. I am already at 79% for August and it is practically all due to the HTTP traffic component! I noticed that the bandwidth traffic really spikes during the days of a new post. Also, I do have videos from Vimeo embedded in my posts, so I am not sure if loading those on my page counts towards the bandwidth. So what can I possibly do? And is this high usage actually just from people visiting and loading my blog post in their browser? Do you have any suggestions which would significantly reduce the bandwidth usage? I can't afford to raise the bandwidth cap either. For reference, I have an installation of Wordpress running on my website. Thank you.


Are copyright notices really required?

Ever since I made my first web page 13 years ago I have followed the pattern of showing a copyright notice in the footer of each page. Over the years the format of this notice has changed in the following way;   * Copyright © `<NAME>` `yyyy`. All rights are reserved.   * Copyright © `yyyy` `<NAME>`   * © `yyyy` `<NAME>`   * © `<NAME>` This has generally mirrored the format used by Google. However, I recently noticed that they no longer display a copyright notice on their home page nor have one in their source code/meta tags. I see they still display it on most (if not all) other pages. I understand that Google are very keen to keep the word count down on their homepage, which could be the reason for this sacrafice, but my question is more general and relates to all websites. Since I've always just done it out of habit, I'm hoping someone can explain if/when I a copyright notice is actually required to protect your content and rights. Also, when it is required, is there a format in which the notice must adhere to in order to be valid?


How to create email request forms and auto-responder?

I'm building a site in css and I'm pretty new to any code or script other than html and css. I'm trying to create a landing page that requires an email from visitors and set up an auto responder to send to that newly submitted email. This would also be a signup for email newsletters. I have some idea how to create the form and have looked into a bit. I don't know how to make it a requirement to get past the landing page and into the actual website or set up the auto-responder. Any help would be much appreciated. Or if someone knows of a source that explains how to do this thing in particular it would be wonderful. I tried lynda.com but everything is so general and I can't seem to find info on exactly how to do this but I know its quite common. Thanks!


Is there any difference, from Google's point of view, on the method used for a 301 redirect?

Hosting a Site with Windows Azure

This is probably a ridiculously simple question, but is there a way for me to host a normal, static website on Windows Azure? I see on auzre.com that they do offer web hosting, but after trying to figure it out myself, and looking for some sort of tutorial, I can't figure out how to upload my files. I work with FTP and DNs stuff all the time, but Azure's really confusing me. I'm betting it's because it's overpowered for what I'm looking for, but I'd still like to try it out.


What browser is sending user agent beginning mozilla/5.0+, tramslates & into &

We've got a website which has been running for a few years now. One of our customers has just started having an intermittent problem. Looking at our iis6.0 logs the service works correctly when they have a user agent beginning "mozilla/4.0+" but fails when the user agent begins "mozilla/5.0+". The particular customer only started having this problem on Wednesday. Does anyone know the browser/upgrade which changes the 4.0 to 5.0? The actual problem caused is that an "&" in a url parameter list is being encoded as "&". Anyone seen anything similar? We have other users sending from browsers with the 5.0+ user agent without trouble. Sorry about the tags but don't have the rep to create new ones. Thanks in advance, Patrick Edit: hi Viper_sb, It is most probably a custom script (I'm primarily a c++ developer so don't really understand). Our site services requests from other customer developed sites, this one was done in Java script as far as I know. we're actually getting a variety of user agents (presumably depending on which of our customers customers is accessing the service), here's a few:               Mozilla/5.0+(Windows;+U;+Windows+NT+6.1;+fr;+rv:1.9.1.11)+Gecko/20100701+Firefox/3.5.11     Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-US)+AppleWebKit/533.4+(KHTML,+like+Gecko)+Chrome/5.0.375.126+Safari/533.4 302 0 0     Mozilla/5.0+(Macintosh;+U;+PPC+Mac+OS+X;+fr)+AppleWebKit/523.12+(KHTML,+like+Gecko)+Version/3.0.4+Safari/523.12     Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-US;+rv:1.9.2.8)+Gecko/20100722+Firefox/3.6.8     Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+fr;+rv:1.9.2.8)+Gecko/20100722+Firefox/3.6.8+(.NET+CLR+3.5.30729)


Share on: FB, Tweet, Digg, Linkedin, Delicious, My mother, ... it's just on fashion, or of some real value?

Nowadays your site is not in fashion if you don't show at least a couple of share buttons like these: ![alt text](http://i.stack.imgur.com/tzX8b.jpg) **Is this just fashion, or do people actually get something good out of it?** When I say _"something good"_ **I mostly mean something that you could measure, and not just the feeling that was good**. Maybe I can better explain with an example: **did you notice (in some way) that many people clicked on those links to share your page/s on those web 2.0 social sites?** And in such a case on which social networks did you see they mostly share your pages? BTW I'm not talking about Google PR, i know all web 2.0 social sites use nofollow everywhere and even hidden links, so they are useless by themselves for PR. * * * **UPDATE:** According to this video, Google's Alter Ego says that they now use in some way data from social sites in ranking. If this is true, it's obvious that the Share on button for FB, Tweet, etc are definitely of some values. But again my question is more about what you noticed **in your real experience** to be a direct benefit of adding those type of "Share On" links on your webisite? I.e. did you see more traffic coming in form FB, or some users who bought your products because of FB or Twitter? Or any other benefits? Thanks


People sign up to my website but they keep entering invalid email addresses (they are not spammers)

I have thousands of users signed up in my site so I have a good amount of statistical data to analyze my problem for you. In the sign up process of my website, the required fields are username, password etc. and there are TWO fields which are asking for email (email and confirmation of email, as usual.) The problem is, that 26% (I just calculated it) of users are entering AND RE- ENTERING (at confirm your email field) wrong email address! I know what you thinking and they are NOT spammers. They are totally legitimate but use the wrong email addresses. Examples of emails...   * `MARY@HOTMAIL.COM` (no comment...)   * `WWW.GEORGE@WINDOWSLINE.COM` (YES `WWW` and WINDOWSLINE OMG)   * `FASDFASDFASDFASFASDF@GOOGLE.COM` (RANDOMNESS) These are just examples so you can have a laugh, the most of the wrong emails are just wrong addresses. I don't know why 26% of users just DON'T KNOW THEIR #e@$@# EMAIL!   1. What percentage of your users are entering (and re-enter in confirm field) their email address?    2. How can a desperate webmaster handle this situation? Of course I can't get in contact with these users, because I don't have their emails! P.S.: Most of my users are of age 30-35+, and they are not English speakers. I can say that internet is about 10 years old (or less) popular in my country. In many cases, I can tell that the wrong email addresses belong to kids who have a better understanding of computers (for example their addresses ends with 1987, 95 etc.).


400 Bad Request in Movable Type import

I have a Movable Type installation running the latest version of MT (currently Movable Type version 5.2.7 with: Community Pack 1.72, Professional Pack 1.53) and my client has provided us with a data export from another MT installation (we're migrating servers) that he would like imported to the new MT installation. Unfortunately, every time we try to execute the import we receive "Bad Request Your browser sent a request that this server could not understand. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request." This is the ONLY part of the MT install which has this problem. I'm about to rip out the import tool and write my own processing script to do the job, since I'm not going to manually add ~750+ blog posts by hand. Appreciate any advice that people can provide!


Optimizing and securing robots.txt

I have a couple of doubts / questions / ideas related to _robots.txt_ :   1. Can we deny website for all bots except for chosen ones in order to tell other bots not to crawl site:              User-agent: *     Disallow: /          User-Agent: Googlebot     User-Agent: bingbot     User-Agent: Slurp     Allow: /person/     Allow: /products/        2. Can we deny whole site and then just specify list of pages we want to allow for indexing like in example above? I do not want to give away URLs that I want to exclude from crawling, as this information can be used against me.    3. Note that we do not have `Allow: /`, so will bot be able to access home page?    4. In example above, will `Allow` be applied for all three user agents on the list or `Allow` needs to be pasted under each user agent?              User-Agent: Googlebot     Allow: /person/     Allow: /products/          User-Agent: bingbot     Allow: /person/     Allow: /products/          User-Agent: Slurp     Allow: /person/     Allow: /products/


DNS and Wildcard CNAME

Whenever I attempt to make a record for *.schneiderdonnelly.com.au and CNAME it, I get two errors:   * You can't mix CNAME/MX records together using the same hostname.   * Domain root's cannot be CNAME's, however you can web-forward this record to www.schneiderdonnelly.com.au instead for the same effect. I've read it's possible so why can't I make it work? I donated $5 to be a premium member and I've been trying to make it work for yonks. http://i.stack.imgur.com/D9Ui5.jpg This is how I want it to appear. The last record. I am prepared to swap DNS providers as long as they're free.


How to stop access of a PHP file from other sites

I read somewhere about hot linking of images. Preventing image hot linking helps to stop bandwidth theft from your site. Would it work for a PHP file? In my case, I am using a PHP file to generate thumbnails from an image. I don't want others to refer this PHP file from their site.


Social media integration solutions

Another question someone posted got me thinking, what are the social media integration solutions that everyone uses? The most common solutions I've come across are the content-sharing buttons:   * ShareThis   * AddThis   * AddToAny How many of you use these or other social media integration solutions? Or do you just create your own sharing buttons? What advantages are there to using these 3rd-party solutions versus creating your own buttons using Facebook/Del.icio.us/Digg/etc.'s code? Another solution I've been coming across more and more, and that I really dislike, are those fixed social media toolbars that many sites put at the bottom of your screen. They stick out like a sore thumb and take up valuable screen real-estate and just look very tacky IMO. How many people use those, and what advantage do you see to using those branded social sharing toolbars? Are there any other solutions out there that you guys would recommend?


Will "performing maintenance" page holder affect your seo and page rankings? If so, is there a better way to handle it?

Let's say that theoretically you run a ecommerce shop. There may be times, once a year, that you need to take the site down to update product information or to do some maintenance. What would happen to your page rankings? I would assume that we would direct any page hit to the maintenance page.


What is the advantage to hosting static resources on a separate domain?

I notice a lot of sites host their resources on a separate domain from the main site, e.g. StackExchange using sstatic.net, Barnes & Noble using imagesbn.com, etc. I understand that there are benefits to putting your static resources on a separate host, possibly with an efficient static-file web server like nginx, freeing up the main server to focus on serving dynamic content. Similarly, outsourcing to a shared CDN like cloudfront Akamai is logical. What is the benefit to using a separate domain otherwise, though? Why sstatic.net instead of static.stackexchange.com? **Update** : Several answers miss the core question. I understand that there is benefit to splitting between multiple hosts — parallel downloads, slimmer web server, etc. But what is more elusive is why multiple _domains_. Why sstatic.net rather than static.stackexchange.com as the host for shared resources? So far, only one answer has addressed that.


Block IP Address using php

For my website i use this php code to block ip addresses.               <?php     $deny = array("111.111.111", "222.222.222", "333.333.333");     if (in_array ($_SERVER['REMOTE_ADDR'], $deny)) {        header("location: http://www.google.com/");        exit();     } ?>      How to re-edit this code to block ip addresses like all addresses starting from "111." or "222." like that? Thanks in advance!


phpBB permissions issue

I'm in the process of installing phpBB, it says I need certain permissions for a few directories (image). I tried changing the permissions via FTP clients but it won't change. FileZilla even gave me this:               Command:    SITE CHMOD 777 cache     Response:   500 'SITE CHMOD 777     cache': command not understood      How do I change these permissions? I'm running Windows Server. Any help? ![phpBB install](http://i.stack.imgur.com/y5mfT.png)


How do I have a page depth > 1 on a single page website?

One of my sites is a single page that focuses on getting the user to call a phone number. In GA, I've set up a Goal for when visitors spend more than 1 minute on the site. I realized much later that GA doesn't trap exit events, so visitors who arrive at the site and click back won't be counted. I'd like to modify that; but that's for another question. I've got a number of users with an Average Time on Site >0 ; and a page depth > 1. I can't figure out how --- My site contains a single page. The number of users with Page Depth 2+ doesn't equal the number of returning visitors - otherwise I'd assume these are people who left and then typed in the url manually. I'm at a loss. Did they just hit refresh? Did they bookmark the site and return to it? (That shouldn't count as 'time on site' though'...)


Somehow Google considers a properly 301'd URL as 200 and is still indexing the new content in old page?

We redirected all the old URL's to new ones properly using _.htaccess_. The problem is Google, somehow is still finding content in the old page (which it shouldn't) and stores it in the cache rather than the new URL. For e.g.:   * Old page: `http://www.natures-energies.com/iching.htm`   * New page: `http://www.natures-energies.com/index.php?option=com_content&view=article&id=760` If you type the old URL into the browser it redirects. If you fetch the old URL as Googlebot in the Webmaster Tools the header says 301/permanently redirected. If I try to crawl as any other bot it still says 301 redirected. Even if you click the old link in Google it redirects to the new URL. Only in its cache it shows the old URL and moreover it shows the new content in it! I am stumped on how Google manages to grab the new content and puts in the old URL instead of the new one! One more interesting thing is that if I try a cache for the new page it shows the cache of the new content with old URL! Any help would be appreciated. I am at end of my wits. I think I have tried almost everything. Is there anything that I'm missing to see? You can use this search to find the old URL's. Maybe you'll some patterns that I missed. `site:www.natures-energies.com inurl:htm -inurl:https|index`.


Optimal GZIP compression level for static resources?

Is there a compression level which will provide an optimal balance between file size reduction and client decompression time/cost? I was wondering which GZIP compression level provided the best balance between file size reduction and decompression time. Compression time doesn't really matter since it will only be compressed once and cached. However, I'm concerned that if I set the compression level too high, any gains from file size reduction will be wiped out by the time and cost required to decompress the file on the client side.


Does an iframe count as a backlink to my domain?

I have the following situation: **Iframe case** web page _www.notMyWebPage.com_ contains an **iframe** that points to my domain (the contents of the iframe are loaded from _www.myWebPage.com_ ) **Link case** web page _www.notMyWebPage.com_ contains a **link** that points to my domain (it points to _www.myWebPage.com_ ) I'd like to know if from the SEO perspective I get the same ranking benefits (i.e., 'juice') **for _www.myWebPage.com_** in the Iframe than in the Link case. Notice that this question refers to the SEO effect on _www.myWebPage.com_ , not on _www.notMyWebPage.com_ , which is the subject of concern of this other question.

How to remove one of two domains on the same site for SEO?

I have foo.com which is set up as the alias of bar.com For better ranking etc I want search engines to only crawl foo.com How do I "remove" bar.com ? Is it the same method as removing www (which I'll also be using) ? if so what's the code ?


Facebook open graph doesn't work

I have used open graph meta tags in my website               <meta name="og:description" content="My page descriptions ..." />     <meta name="og:title" content="سخت‌افزار20" />     <meta name="og:type" content="website" />     <meta name="og:url" content="http://www.hardware20.com/" />     <meta name="og:image" content="http://www.hardware20.com/apple-touch-icon.png"/>     <meta name="og:site_name" content="hardware20"/>     <meta name="og:locale" content="fa-IR" />      But facebooke does not load Image & Descriptions, When I try to share a page.

Allow other people to upload to my home web server (inc mysql)

Apologies if this is on the wrong place. I've set up a web server at home, it's basic and is currently running using xampp, I plan on replacing it with an old mac g5 soon and mamp or individual components for php etc. I've not done this before so it's all a bit new. I know that I can set up a new dir for a friend and allow them to upload their site to the server so long as it doesn't involve them creating databases. My question is how can I imitate what web hostin companies do? I'd like to be able to give him a user an password and for him to then be able to have the same capabilities as myself although restricted to one folder of course. I've googled quite a lot but haven't come across anything that makes it clear. I understand an option is cpanel but I'd rather find a free alternative. Could someone explain if its doable and if so would it possible to point me in the right direction or state the problems etc that might prevent this from happening. Any and all advice appreciated. Thanks.


How to see all changes to the HTML5 CR?

On 2013-08-06 the W3C published a new HTML5 Candidate Recommendation. How can I see what was added/removed/changed since the previous Candidate Recommendation from 2012-12-17?   * In _Differences from HTML4_ there are HTML Changelogs, but the last changelog is for "Changes from 14 September 2012 to 6 May 2013".   * On http://html5.org/tools/web-apps-tracker (resp. the mailing list) I can see all commits to the WHATWG version. However, it would be too complex to retrace all these commits from eight months, and there are also many things different in the W3C version.   * I tried to make a diff with the single page documents, but it gets really muddled (many things moved etc.) Of course this question is not limited to the two mentioned CRs, it applies also to future publications of HTML5.

Google Wallet use case

I sell small game servers on a website and used to be able to have customers pay through Google Checkout. Since that has been replaced with Google Wallet, I've been trying to set it up. However, I think I have to "apply" to use the buttons now and the requirements are:               -Have the ability to process their own payments with a qualified payment processor     -Maintain PCI compliance     -Sell physical goods online or through their Android native application, and do not sell any digital goods through their Android native application      Since I don't meet any of these requirements, is it true that I cannot use any Google service as a payment method? Am I doing this wrong? For reference, I'm getting them from this site: https://developers.google.com/wallet/instant-buy/ then click "sign up"


htaccess redirect pages that don't exist

I have a website that has a little over 100 members. Each member gets a replicated website, and by default the software we use sets up their replicated website at a url like: `domain.com/?username` "username" being the username they registered with. What I'm wanting to do is allow the users to access their replicated website without having to type the question mark before their username. For example, I would want `domain.com/username` to redirect to `domain.com/?username`. I tried adding the following to my htaccess file: `Redirect 302 /username domain.com/?username` This doesn't work, it just gives a 404 not found page when trying to access `domain.com/username` because it doesn't actually exist. Basically, I just want my users to be able to access their websites without having to type the question mark. I hope I've made what I'm trying to accomplish clear. Is this possible? Any help is greatly appreciated. Thanks.


123-reg missed domain registration

A few weeks ago I renewed a domain that was coming up to expiration for 10 years with 123-reg for £114.00, it was paid for, we received the invoice stating it was paid - and the control panel expiration date has been updated to 2023. Yesterday upon receiving an email warning that the domain was due to expire, I thought I better contact them and check that the email was sent in error. It turned out they had 'missed the domain for registration', it expires day after tomorrow and they say they don't know if it can be resolved in time. This is quit unusual and obviously ridiculous service from them, and although if it does expire we'll probable be able to get it back, all our company emails use the domain so there will certainly be disruption to our business - plus the time I've spent trying to get this sorted already. Could someone let me know what the best course of action we should take here, is it likely they'll renew it in time and what sort of compensation if any we should ask for? **EDIT** For anyone interested, there's some confusion on their end - they have agreed they won't allow it to go down whilst they look into it. Would have been nice to provide that peace of mind originally, but hey ho.


Using CNAME to point domain to Heroku Server

We purchased and installed an SSL Certificate on our Heroku app, and install the SSL endpoint. The domain is using nameservers that point to a separate cPanel hosting account. I have tried to add a CNAME record in cPanel that points to our Heroku secure endpoint:               example-7245.herokussl.com      I setup the CNAME like this:               Name: *.domain.com.     Type: CNAME     Record: example-7245.herokussl.com      But is has been a whole day and the url still doesn't to heroku. Is this even possible to do this way? We need the email to run off the cpanel host so if we could just use a cname record for the domain server it was perfect. Thanks for any help.


If I remove my A record, will it mess up MX records on that domain?

I am using DNSimple and S3/Cloudfront. Following their recommended configuration looks like this:               myapex.com ------ REDIRECT --> www.myapex.com     www.myapex.com -- CNAME -----> lkj32lkj323323.cloudfront.net      This is all bacon gravy. I'm about to make the change though, and I got nervous because I have a lot of existing MX records. They all point to Google services though, as we use Google for our email. Am I likely to break email or other services by removing an old `A` record? Do `MX` records do something special with the zone apex or `A` record?


Can I dynamically set the SSLInsecureRenegotiation Directive?

We're running Apache 2.2.22 with OpenSSL 0.98, one of our Citrix NetScaler Hosts cannot send a client certificate after handshaking SSL as we have to set SSLInsecureRenegotiation off as a security standard. Is there anyway to dynamically set this directive based on Remote_Addr? I have tried so many settings but as designed I guess, there doesn't seem to be a way of selectively allowing SSLInsecureRenegotiation for one user agent or IP? We've already patched to latest NetScaler 10, but after the SSL initial handshake a renegotiation request is sent back from Apache to the NetScaler because as a client cert is required for a LocationMatch, this is never responded to leading Apache to terminate session. - http://tools.ietf.org/html/rfc5746#section-3.5 . We're told by Citrix that downstream rules are normally on a "trusted" network, and not supported using the client method, is it possible to differentiate between requests and how the SSLInsecureRenegotiation directive is called by host identity of some sort or IP? Many thanks.


DNS MX and NS entries

I was wondering about my domain and if next is afordable. First of all this is my "architecture":   * Domain registration at GoDaddy.com    * Hosting at Dreamhost    * mail at google apps Until now I setted up the google apps MX entries in my domain through the GoDaddy manager, but now what I want is to set up the hosting I have hired from Dreamhost. I understand that all I have to do is to setup next Dreamhost NS entries into the GoDaddy domain manager:               NS1.Dreamhost.COM. 66.33.206.206 NS2.Dreamhost.COM. 208.96.10.221 NS3.Dreamhost.COM. 66.33.216.216      My question is, will my mail keep working right as soon as the MX entries I already setup into the GoDaddy are the Google Apps ones?


Website design using responsive approach or mobile site

I have been looking for mobile desktop website solution & I am confused with the information available on internet. In some case article talk about Responsive approach with the future but i am sure it has its own limitation. Google recommends it which I am not sure is it for their own inconvenience. On the other side jQuery Mobile is great to work with, both approach's might have there own pro - cons. I would like to have expert opinion on this:   1. What is better responsive website or separate mobile website?   2. Which is better from SEO point?


Freelance Terms

I am having many arguments with my client about the terms of a large project and need some advice. The client is a middle man linking me up with the company that needs the website, so the end customer is this company that my client knows, that I have no connection to, other than through him. I agreed to do freelance work for an extremely reasonable price, way below what its worth. **What (I) the freelancer wants** I tried to come up with an extremely reasonable contract that contains information about payment due dates, if any changes are made to project scope additional fees apply, project files are to be delivered after no balance remains, $30 late fee per day will be applied daily after exceeding 5 days after the due date. Are any of these terms unreasonable? Aren't the terms usually a lot worse? **What the client wants** The client refuses to adhere to my contract and wants to create his own contract that says that payment due dates may change at any time and I will be paid 7 days after I show progress with the site (which can be whenever he wants). Progress with the site will be shown using CFT which forces me to transfer files to his server, so this means I deliver half the project before I get paid and last but not least, no late fees. Since when do clients make the contract between them and the web developer? I'd appreciate any advice, with this situation. Many thanks in advance!


Importance of 'href' attribute within an <a>

I am aware of the 'content is king' seo rule, but I'm also wondering whether empty `<a>` HTML elements is a relatively big downside regarding SEO. To be more precise and actually cut to the chase, I want to use this javascript plugin http://kirkas.ch/ascensor/#/Home for a site. As you can observe, the "navigation bar" (bottom right) uses empty `<a>` elements for navigation.


Not index page that doesn't have relevant content?

I have a large software website and on each application we let users add comments, reviews and so on. Each of these pages are called for example "Comments About Firefox", "Firefox Reviews" and so on. If we don't have any reviews or we for some reason KNOW that the visitor from Google would be disappointed should we add "noindex" to that page? Or should we just let Google decide if they want to rank us or not?


Preventing indexing duplicate content by search engines

I am in process of migrating my old domain (www.oldurl.com) to new domain (www.newurl.com). Almost all the content,URL structure as well database is same except for few URL's and only difference will be in the domain name. I have made entries in the Apache's .htaccess file to set 301 redirect and currently have blocked all search engines from crawling my new domain by setting in robot.txt file. I am not sure how i will handle the duplicate content issue as when i will make the new domain go live.   * Should i block search engines to index/crawl my old domain? i am new to this field and not sure if this is actually any duplicate content issue or not.


What are my options for Web 2.0 gallery software?

My question is: What are my options if I need a Web 2.0 gallery software that work in a very similar manner to this _removed_ web site. Essentially: users can create account, then create and manage their own galleries. And all other users and guests can see these galleries, add tags, comments, etc. Basically a community driven gallery web site. When it comes to "normal" cms I know a lot of good options, but I never worked with any gallery management software... If you can suggest me some good solutions (free) it would be great! Also: If you by any chance know what software is used at this _removed_ website it would be even better, because this solution suits me the best and I would have used this engine, but I cant find any information on what this engine is and if it is even public, or privately developed thing.


Where can I register a .name domain?

How do developers access my site during construction?

So I just finished my psd's and I am going to send them to a front end developer, but I'm at a loss at to the logistics of it. Do I just send them to the front end developer and have them upload them to my server, or to their test server? And then when I send it to backend development, do I just give the programmer my hosting credentials, etc, so they can login and work on my project? Is this how it works?


Is there a way to make links to search photos on my site automatically with Google Image Search?

I have a website where members can upload photos. I am trying to make sure that these are photos that members have the rights to, so when I am concerned, I do a search using Google image search to see where else the photo can be found on the Internet. (http://www.google.com/imghp) I know there is a Firefox/Chrome extension to allow search by right-clicking an image on a site, but I don't always have a desktop version of Chrome/Firefox available (I often do these checks from a tablet or mobile phone). So, I would like to find a way to build links on my own site so that I can simply click the link for a photo and then perform the image search on Google. Is there a way to do this? I tried looking at the search queries that Google image search produces, but these look different than normal Google search queries when you choose the option to paste the URL in at the start.


Is it correct to use canonical and alternate hreflang links in the same page?

I have a multilingual site and I think both, canonical URL and alternate hreflang URL should be defined. The URL structure is very simple: Language, tag and page title.   * Structure: http://domain.com/lang/tag/page   * Example: http://domain.com/en/funny/man-walks-on-banana The page has multiple tags. While going through pages under one category, the category name should be maintained in the URL like following:   * http://domain.com/en/funny _clicks a link_   * http://domain.com/en/funny/man-walks-on-banana _clicks "next"_   * http://domain.com/en/funny/woman-walks-on-banana _clicks "next"_   * http://domain.com/en/funny/some-other-funny-stuff When some of these pages is also related to the tag "accidents" and many more tags, it means that the page has multiple URLs, which causes duplicate content:   * http://domain.com/en/funny/man-walks-on-banana   * http://domain.com/en/accidents/man-walks-on-banana   * (same page, different URL, bad) This will be handled by defining a canonical URL. We have decided not to create "sub-tags", so we need to decide which tag is the most important one for this content. So under whatever tag the page is being viewed, canonical URL refers to:               <link rel="canonical" href="http://domain.com/en/FUNNY/man-walks-on-banana" />      Now the question occurs when the site is multilingual. According Google's instructions I should set an alternate link hreflang to the finnish version of the page.               <link rel="alternate" href="http://domain.com/en/funny/man-walks-on-banana" hreflang="en" /> (english versison of the page)     <link rel="alternate" href="http://domain.com/fi/hauskat/mies-kavelee-banaanin-paalta" hreflang="fi" /> (finnish version of the page)      Alternate hreflang-links are defined in both versions, but in both versions there should still be the canonical link, so that the page is under the main tag, in its own language. If we assume we're on the english version of the page "/en/sometag/man-walks- on-banana", would it go like this:               <link rel="alternate" href="http://domain.com/en/funny/man-walks-on-banana" hreflang="en" />     <link rel="alternate" href="http://domain.com/fi/hauskat/mies-kavelee-banaanin-paalta" hreflang="fi" />          <link rel="canonical" href="http://domain.com/en/funny/man-walks-on-banana" />      Is this a proper way to do this or not? Does the defining of a canonical link effect to the alternate hreflang-links or not? Does Google understand what I'm trying to tell them here? I hope you do. If so, what would be the proper solution? Thanks.


Nginx and Google Appengine Reverse Proxy Security

The scenario is that I have a Google compute node running Nginx as a reverse proxy to the google appengine. The appengine is used to service REST calls from an single page application (SPA). HTTPS is used to the Nginx front end from the Internet. Do I also need to make the traffic from the Nginx reverse proxy to the appengine secure by turning on HTTPS on the appengine? I would like to avoid the overhead of HTTPS between the proxy and the backend. My thinking was that once the traffic has arrived at Nginx encrypted, decrypted in Nginx, and then sent via the reverse proxy inside of Google's infrastructure it would be secure. Is it safe in this case to not use HTTPS?


How do I verify the ownership of a domain from Namecheap to use Google Apps?

I registered a domain with Namecheap.com, and started the Google Apps registration process. After the initial data filling, google apps wishes me to prove the ownership of a domain, and has given me 4 choices:   * Add a DNS record to your domain's configuration    * Link to your Google Analytics account    * Upload an HTML file to your server    * Add a meta tag to your site's home page What is the differences between these, and how do I (if someone knows perhaps how to do it on Namecheap, it would be even better) complete this step in the process? I would appreciate any advice you might have.


Javascript not loading from local drive

I'm overlooking the obvious...Modifying an index page on local hard drive before uploading it to server. And the javascript is not loading. This doesn't work:               file:///Users/meltemi/Sites/mysite/index.html      But, when page is uploaded and served from Apache then the javascript works:               http://www.mysite.com/index.html      Site directories are identical both locally and on remote server. I have tried this with Safari 5.0.5 & Firefox 4.0. code excerpts, though I don't believe it's a code issue:               <!DOCTYPE html>                        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">         <link rel="stylesheet" type="text/css" media="screen" href="css/main.css" />
                                    ...


Websites sharing the same IP address

I have always been confused by the idea that multiple websites sharing the same IP address. I mean if there is a webserver out there that has an IP address. I can simply key in this IP address with the right port such as 80 and the destination gateway knows which server to forward this incoming request. This case, port 80 is the webserver and the website is served out to the client. However, I do not understand how two websites can be hosted on the webserver and one IP address. Let's say the two websites with names of abc.com and xyz.com are hosted on the same webserver with one IP address. The DNS server that I use such as one from my ISP can resolve the names with the IP adress just fine, pointing my web browser to the correct webserver, but my confusion is how the webserver know which website to serve out? I always thought that the only way to differentiate between different websites on the same webserver is their respective port numbers. In other words, if the incoming request is on port 80, it's abc.com and if it is port 81 it is xyz.com. Obviously, I am not putting in xyz.com:81 on my web browser so it uses port 80 by default. Then why do I get the actual xyz.com website in return and not abc.com?


Whatchamacallit: You know how there are breadcrumbs and sliders and whatnot

What do you call it when a web site (especially corporate/retail) has a series of rows with thumbnails, each with a little caption/description beneath explaining some benefit or feature of a product or service. Is there a name for this? I'm building a theme that incorporates this kind of design and I was hoping there is some kind of shorthand for this design feature. If you don't know what I'm talking about, check out one of the links below. http://themeforest.net/item/revolution-minimalist-business-html- template/full_screen_preview/2295335 http://themes.two2twelve.com/preview?theme=freshserve


Can I programatically update a Google Analytics filter?

We have a constantly changing list of IPs that needs to be filtered out of google analytics, is there some API, or way to fetch the list of IPs to be included in a Google Analytics filter?


Canonical links and best way to use parameters with url rewriting

I use my own custom routing module in PHP and mod_rewrite. A typical main page URL looks like this: `http://www.example.com/services` There's a large part of the website that displays the products on the site (6000 pages indexed in Google), for which the URLs look like this: `http://www.example.com/products/model/bmw/cat/lubricants` The problem is that in some pages, there are links to the same pages from above that also contain a parameter: `http://www.example.com/products/model/bmw/cat/lubricants/highlight/value` So those URL's have the same content, the second just has a parameter that is used to highlight a certain product. The problems I have are:   * Google indexed a version of each of the URL's. I don't want visitors to land directly to the version with the _highlight_ parameter, so I don't want those URLs indexed   * In Webmaster Tools, the pages appear with duplicate title (don't know why I don't get a warning about duplicate content/meta/etc too, because they're the same, but..). So this has to be fixed. I can think of these possible solutions:   1. Use the `<link rel="canonical">` when the page is requested with the _highlight_ parameter and point to the one without it. Leave the URLs in the form they are now. Wait for Google to merge them in time.   2. Instead of "rewriting" the _highlight_ parameter (with /), append it the classic way: `www.example.com/products/model/bmw/cat/lubricants/?highlight=value`, and add _highlight_ in Webmaster Tools to the ignore list of parameters; that way, parameters that don't really change page content would be distinguishable by search engines. This solution would also shorten the depth a little (as seen by search engines), and I believe it's a good thing from a SEO standpoint.   3. A combination of 1 and 2: canonical links and classic parameters. Again, should I add the parameter in Webmaster Tools in order to _force_ Google merge the results and not wait for a crawl of those pages?   4. This one is stupid, but: add _highlight_ in Webmaster Tools and keep the URLs as they are, but I don't think it works this way and Google expects only url's in the form ?x=y in order to detect parameters and exclude pages from results. **So, which of these would work best? Is there something else I should do?** There are only 300 results indexed in Google of pages with the parameter. I wouldn't mind to lose them, but a "merge" with the no-parameter pages would pe preferred. And that mention in Webmaster Tools about duplicate titles somewhat bothers me. Does that affect ranking of those pages (or their no-parameter correspondants)?


Recomendation for Webshop with API

I'm searching for a webshop. The problem with my search is, that the webshop- software of my choice needs to have a useabel API or some interface for external applications. E.g. i need to place orders by an external application or need to get product descriptions or warehouse stock from the external application. I somehow would like to have a webshop wehere the webinterface is just one way to interact with the whole system. There are some other requirments, which have to be fullfilled, but i guess they are kind of common:   * running on linux   * MySQL (we already have MySQL-replication and backup in place)   * i like open source but i'm willing to pay for it, if it's worth it I found some webshops on the net - but perhaps you can tell me, if theres any hope for a webshop with a good API before i go and test all of them, on the first look i didn't find any docs about any interface to external applications for any of my search results. Thank you!

What resolution in sitemap.xml image attribute?

I'm just creating a sitemap for my page and I found these aspects for creating it on Google: https://support.google.com/webmasters/answer/183668 There is a attribute for images, but my question is: Does anyone know what kind of image site I have to put there? There is a big image on the page and should I include the full resolution path or a path to a thumbnail? Anyone got experience with that?


Redirection 302 during DNS update

I will migrate my website from server A to server B. During the DNS propagation, the users arriving on server A will be 302 redirected (rewrite rule in Apache) to a temporary alias on server B. Example: A (http://www.mywebsite.com) -> B (http://mywebsite.com.myhoster.com) When their DNS is updated, they will go to server B (www.mywebsite.com). After a few days, we will stop server A and remove the alias on server B. Is it a good practice (SEO and technically)? Or do you have an other idee? **Note:** The TTL of the DNS record has been set to 300 to speed the DNS switch.


VPS DNS Records Multiple Domains

I am very new to using a VPS (two days old) and have a limited understanding of hosting in general, so sorry if this is a very simple or ill-explained question. I just purchased a VPS with plesk installed and am in the process of pointing my domains to the new server. The server has the following nameservers: ns1.mydomain.com (123.123.123.123) <- fake ns2.mydomain.com (123.123.123.124) <- fake What I don't understand is now that I have pointed my domain to ns1.mydomain.com and ns2.mydomain.com how would I point another domain of mine to that server? I have setup a domain in my plesk control panel, does this happen automatically? For example, if I setup "anotherdomain.com" in the cp, can I just point "anotherdomain.com" to ns1.mydomain.com and it will work? Help!


Canonical created by WordPress SEO plugin by Yoast

On a WordPress website, WordPress SEO plugin by Yoast creates this weird canonical link. Basically the website name is `www.test.com` and when I inspect the webpage at `www.test.com` it shows me this link:               <link rel="canonical" href="http://www.test.com/">      This looks completely wrong to me, because canonical should be the same content on different URL but the URL is the same!

What happens when a temporary self-signed SSL certificate is replaced with a trusted certificate?

My website is in beta stage. I am using a temporary self-signed SSL certificate with a short expiry date. Beta users have to add the exception on their browser to access HTTPS on my website. Subsequently, I will be replacing the certificate with a trusted one from a Certificate Authority. Upon replacement of the self-signed certificate with a trusted certificate, do these beta users need to do anything to access my site on HTTPS, such as deleting the self-signed certificate on their browser manually?


Can government suspend any kind of domain?

I am aware that country-wise domains like `.uk, .in, .se` can be suspended upon government request but does this apply to `.com, .net, .org` as well? If yes, under what conditions does ICANN puts them down? And how are websites like _The Pirate Bay_ (Government and companies are concerned about piracy which makes the website illegal) stil running if they could have been put down?


Two different domains as one user session in Google Analytics

I have two websites that are run as the same service. Each domain offers articles from a different market. At the top of each page the two domains are shown as menu options. If a user clicks one they can switch to the other domain. See here: http://www.cgtag.com Each domain has a different Google Analytics account, and when a user switches domains Google is counting this as a new session. It's listing the other domain as the "referral" for that new session. When the user switches back to the first domain Google is counting this as a returning visitor. This is messing up my reports. Showing returning visitors values that are higher than reality. It's also increasing hits on landing pages when the user switches, and listing the other domain as a referral site. I've found tips on how to list two domains as one website, but that results in merging the data. I want to keep the two domains separate so that I can track each ones performance, but I don't want to count domain changes as new sessions. Maybe something like treating the two domains as subdomains.


external website storage

One of my clients is a business consultant, and stores powerpoint presentations on her website for conference attendees to download after a conference. There are 91 files totalling 111MB. I want to host these outside of my own web hosting account, to save disk space and bandwidth. Any recommendations on (hopefully free) providers? I just signed up for a free web hosting account with host-ed, and they required a domain be attached to the account.


Does MediaWiki have a News extension?

Many CMS' have news on the front page, where e.g. the sysop/webmaster posts about down time and other important news. Often these can be scheduled, so that you e.g. write on Monday, and wants it to be visible from Tuesday to Friday. **Question** Does MediaWiki have something like that?


Can a sitemap change result in a drop of visits?

I recently restructured and resubmitted the sitemap for a website of mine in GWT. The old one was built by a script I acquired, which had its flaws but dit the job. After having implemented URL rewriting, I decided to write my own sitemap generator, in order to have a solution which perfectly fits my requirements and provides much better and accurate info than the old one. The integration went well, GWT displayed the green tickmark and the correct number of URLs. Around the time I have submitted the new sitemap however, I noticed a big drop in visits to the site. Is that normal behavior when one makes an important change to a sitemap, or is it pure coincidence and I need to look for the reason for declining visits elsewhere ?

Issue with permanent redirect implementation

I have a tricky problem related to 301 redirections I badly need help with. I tried to implement these via .htaccess, but ran into trouble. The start of my .htaccess looks like this:               SetEnv PHP_VER 5     Options +FollowSymlinks     RewriteEngine on          # Redirect non-www to www     RewriteCond %{HTTP_HOST} !^(www\.|$) [NC]     RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]          #--- GENERAL ---     RewriteRule ^index\.html$ index.php [L]     ...      When I try to put a permanent redirect to index.php by adding R=301 in the square brackets, I get a 404, and I have no idea where the error comes from.

When the canonical page itself changes URL

This is a continuation of the question: How to handle canonical URL changes like Stack Overflow. Say I have the canon URL: `questions/11/car` <---canonically-linked-from--- `questions/11/` What will happen if I want to change the canon URL to: `questions/11/car-with-sgx` Obviously, `questions/11/` will point to the new canon URL. But how should the old `questions/11/car` change to the new one? There are two ways:   1. 301 redirect that to new canon URL   2. the old canon URL canonically link to the new canon URL According to this post: > [By using canonical link instead of redirect,] OldPage.html’s rankings will > drop over time due to fewer internal links, but the canonical tag won’t make > it disappear entirely. It could theoretically remain in their index until > one of the following occurs: > >   1. it is redirected permanently via 301 >   2. it returns a 404 for an extended period of time (they will keep > checking for a while before dropping a URL) >   3. a meta robots “noindex” tag is added > If this is true, I really need to use redirect from old canon URL to the new canon URL, which means I need to keep a log of previous old canon URLsof this content, so I know when I can redirect. This is a bit of a hassle to do.


Which web framework uses 'eservice_enu' as part of its default path?

I've seen `http://example.com/eservice_enu/` all over the place, especially on sites that handle payments. Which framework is this? I realize any site could choose this path component arbitrarily.


Shifting from no-www to www and browsers' password storage

I created a website having user-registration system and invited my friend to join it. I gave him the link of `no-www` version: `http://mydomain.com` but now after reading this and this, I want to shift to `www.mydomain.com`. But there's a problem. I saw that my browser is storing separate passwords for `mydomain.com` and `www.mydomain.com`. So in my friend's browser his password must have been stored for `no-www`. That means after I shift to `www` and next time he opens the login page, his browser wouldn't auto-fill the username and password fields and there will also be an extra entry (of `no-www`) in his browser's database of stored passwords. Can this be avoided? Can I do something that will convey to browsers that `www.mydomain.com` and `mydomain.com` are the same website? I already have a CNAME record for `www` pointing to `mydomain.com` but it seems that search engines consider CNAME as alias but browsers consider them as different websites, I don't know why.


Creating a Facebook web app - would I be legally responsible for the data?

I'm creating a discussion forum "web app" for a friend. He want's me to add Facebook login to his site by creating a Facebook app. Am I legally responsible for the data if I create the app under my Facebook account? Who should register the Facebook app - the developer or the owner? Can the right to the data be moved to a third-party after I finish configuring it? I wish to prevent any possible future problems with privacy issues, I'm just doing a job, and I really don't want to have anything to do with the data.


Consolidating to one page when multiple pages appearing in SERPs

I've got a web site which for historical reasons has two or three pages that appear closely in serps for any given search term. The site is a spanish language site with two different but related domains, `capital-federal.enbuenosaires.com.ar` and `www.enbuenosaires.com`. An example would be the search term: "propiedades en venta en almagro" (properties for sale in almagro). PR1 - SERP 1 Position 3: http://www.enbuenosaires.com/almagro-ventas.html PR1 - SERP 1 Position 6: http://capital- federal.enbuenosaires.com.ar/m-almagro/departamentos-ventas-es_AR.html This is one isolated example but there are many (thousands) of pages some appearing high up, some further down in the SERPs. The pages in the `www.enbuenosaires.com` page are newer (since 2013) and updated in real time. The page in the `capital-federal.enbuenosaires.com.ar` domain heavily interlink to each other and are older (have been around since 2007) and are updated weekly. Many of the pages seem to have reasonable PR (0,1,2) and have been indexed without a problem. My question is what should I do? My feeling is that I should reduce the number of pages in order to "distill" and concentrate page rank within the site and thus appear higher in the SERPs. Things which occur to me are:   1. prune the site (remove one of the pages) and 301 from one of the pages to the other   2. prune the site (remove one of the pages) and 301 to a central "sitemap" page with links to the "canonical" landing pages   3. generally reduce the pages via 301 to the home page of `www.enbuenosaires.com`   4. leave it as it is Any suggestions or comments with reasoning very welcome.


can a web design agency take credit for my work?

Recently, a client and I ended our work relationship and he will be taking his business to a web design agency. I've noticed that it is standard practice of this agency to put "Web site designed by " (which I found quite amateurish to be honest). but what happens if the agency place that text on a web site that I designed and they just happen to be maintaining it? I'm using CSS frameworks, JS plugins, and some stock images released under GPL and MIT licenses if that matters. If this agency is placing that text and taking credit for my work, can I ask them to remove it?


How do I get Images for my site to Return in Google Searches

I know when I search Google for specific things I get back images underneath some sites. How do I get that to work for my site? I have even seen some sites that will return 4 or 5 images for the the site that are all relevant to my search


Google sitemap HrefLang tag without the main site url

We have websites with multilingual content. e.g.   * `http://www.example.com/about-us/`   * `http://www.example.com/en-HK/about-us/`   * `http://www.example.com/en-GB/about-us/`   * `http://www.example.com/zn-CH/about-us/` We need to configure the hreflang tags in sitemap for Google to know that there are alternate links for the same pages in different languages. I know for the above example that my sitemap URL tag would look like this:                 <url>         <loc>http://www.example.com/about-us</loc>         <xhtml:link rel="alternate" hreflang="en-GB" href="http://www.example.com/en-GB/about-us"/>         <xhtml:link rel="alternate" hreflang="en-HK" href="http://www.example.com/en-HK/about-us"/>         <xhtml:link rel="alternate" hreflang="zn-CH" href="http://www.example.com/zn-CH/about-us"/>         <changefreq>daily</changefreq>         <priority>0.8</priority>       </url>      However, if I don't have the main URL but just the last three ones with en-HK, en-GB and zn-CH, then how should my URL tag look? Should I just skip the loc tag and keep the three xhtml:link tags? Or can I specify any URL in the loc tag and put the remaining two in xhtml:link tags? I am new to Google sitemaps. Any help is greatly appreciated. Thanks, Rashmi **Edit** : From the answer posted on http://stackoverflow.com/questions/18423624/sitemap-for-domain-with- multilanguage-site/18423803#18423803, for my example with sites in en-HK, en- GB and zn-CH, should there be three URL tags, with each of them assigned to loc with the other two in xhtml:link?


Google Analytics, how to track number of banner shows as events?

Well, not exactly banners, I just used this word as it is easier to understand in a title. So, I have 16 different CTA "boxes" with a couple lines of persuasive copy and a CTA button. I want to test which one performs the best. I am showing the boxes randomly and counting button clicks as events in GA. However, without knowing how many times each CTA "ad" has shown, number of button clicks doesn't say much. So, with Google Analytics, how do I trigger an even every time such CTA box is shown? It's basically a DIV that I'm in need of placing some javascript to.


How to avoid google from indexing like example.com/post/post/post/1-foobar.html?

I have a weird anomaly with one project. Where Google is indexing sites like: > example.com/post/post/post/1-foobar.html While it should do it like: > example.com/post/1-foobar.html I just recently added canonical tags, so ultimately it should use those right? And I think the problem is also in my page display script. So it doesn't give 404, if the format isn't correct. However.. **How on earth does Google even get to those links?** Is it because of `<a href="/post/1-foobar.html">Example</a>`? And also I had baseurl set in the head. And it somehow, thinks its a directory and goes on and on. I have set all my links `<a href="http://example.com/post/1-foobar.html">Example</a>` now. But I really don't see the point, its just an extra bytes to load..


Rewrite URL with masking from HTTP to HTTPS site (on a different server) are certs needed on first server?

I have a *:80 virtual host in Apache 2.2.15 which is just a bunch of URL rewrites like:               ServerAlias foo.bar biz.baz tit.tat     RewriteRule / http://somesite.com (R=301,L)          ServerAlias differentsite.com example.it     RewriteRule ....      I want to do a masked URL rewrite so babysnakes.com goes to https://dancingfool.com/moms.php I tried using mod_rewrite with P flag and I tried mod_proxy and then realized it doesn't handle SSL proxying, that mod_ssl should handle. What I am not clear on is whether I can do SSLProxyEngine in a non SSL vhost config (no certs defined etc).


Google Analytics showing more unique visitors than there are pages on an intranet site

I take care of a company intranet and measure the traffic with GA. I am absolutely sure that there are no more than 5000 URLs in our company and it is impossible to check the intranet from outside the company network. Yet when I check the number of Unique Visitors (UV) in the last year GA says there were 36.500 of them. How is that possible? I thought UV should measure each URL only once in the given time period. Could anybody explain how this actually works? Can it be that the cookie trackers expire after some time and are counted more then once?

What are some main differences between EC2 and S3 services offered by Amazon?


My archives are beating my current content, how do I stop from competing against myself?

I've inherited a site with about 15,000 pages going back 16 years. Often current events are outranked by previous events. What are the best techniques to make sure that I'm not fighting against myself while still keeping old content (the long tail eh?) available to search engines? Currently 50% of the site or less is data driven.


Will google "forget" unlinked pages?

If i remove all links to a page, but do not delete the page from the site (nor block it from being requested), will google eventually "forget" about it when it reindexes the site? Assuming of course there are no other links to the page somewhere else externally. Or will google continue to request the page and verify it in the index and keep it around so long as it returns a valid page? Is this similar for Bing et al?


Sending low volumes of HTML email from my web app

Using AngularJS and Firebase I am developing a small scale social-type web app (max. hundreds of users) that features an invite system, where existing users invite people they know and the system sends out an email for the invite. Invite emails are triggered by a record being added to Firebase, and Zapier detects this and sends an email from a dedicated Gmail account. The system also has a simple user-to-user message system, and emails are also sent if a user receives a message from a fellow user. For the prototype stage Gmail seems fine. I've tested sending emails to Yahoo and Hotmail/Outlook accounts and they've got through. Even in a production version there'd be a low volume of email -not more than a few hundred a day, if that, so Gmail's limits wouldn't be a problem. However for a production version Gmail doesn't look like it would work. Firstly, Zapier is only able to send plain text emails from Gmail in a zap, and I need to send HTML links in the emails. TBH I've very limited understanding of email systems but I've read about the difficulty of programmatic email sending (spam filters stopping a lot of legitimate mail). My newbie assumption is that my Gmail emails are not being filtered as spam by Yahoo and Hotmail because Gmail doesn't get used by spammers given its per-day send limit. Zapier also offers Mailchimp, Mailup, Mailgun, Mandrill, Alphamail and Sendgrid for outbound email. As far as I can tell, whether or not an email gets through spam filters depends on things like building up a reputation for your IP/domain, but I'd need invites to work as soon as the production version gets its first user. Could one of these offer what I need? I need to ensure emails are not filtered as spam. I can ask users to add a personalised message to invites, but beyond that, what can a system such as mine do to ensure the messages are not filtered as spam? (The prototype also does not have a "proper" domain name, but the production system would need one, and emails would need to come from that domain.)


How to dump a MediaWiki for offline use?

I would like to be able to make an offline version of a MediaWiki site on a weekly basis. The DumpHTML extension actually does what I want, as it dumps all articles and media files, but I can't see any index of all the articles it have dumped, so I can't navigate in the dump. Reading about the XML dump feature MediaWiki have, I wonder if it would be possible to either use a program to view these files or perhaps convert them to html? Or are there other ways to make an offline version of a MediaWiki site?


web design quote wrong

What is the best way to make the customer happy after a wrongly calculated quote? I calculated some functions to about $280 when those functions are really simple. I thought they would have been harder but after the customer explained I realized he was right and those functions could have been easily done for like $50. He finally decided he doesn't want the functions. Now I am not sure what to do, I don't want him to think that I have really expensive prices since that would be bad for my business. But at the same time I don't think I can tell him now that I can do the functions for $50, since he will think I was trying to steal money from him with a really high price before. I really thought at the first the functions were much more complex. Thanks for any advice!

Can I use both Digest and Basic Authentication on the same directory in Apache?

The reason I would want to do this is to support very old browsers (e.g. IE 6) that does not implement the more secure Digest method. If all new clients advertise the types of authentication they support in the HTTP protocol, this should be doable in principle. If a client does not advertise that, Apache should fall back to the Basic auth scheme. The advantage over using Basic auth is apparent: it would prevent passwords to travel in clear over the network most of the times, since the new browser are the majority, while still supporting some very old browsers that are still around. In other words, it would increase security.


When using Google Sites with a Godaddy domain, how do you alias example.com to www.example.com?

I know how to do this in an Apache2 config file and my own DNS configuration... But here I'm forced to host the site at Google Apps and the DNS at `Goddady.com`. What's the easiest way to alias `example.com` to `www.example.com` in this situation? I'm sure I need a forwarding mechanism.

Using <audio> in Firefox with JavaScript

I am trying to implement background music on a website using the audio object, which is controlled by a JavaScript, I have posted a question about this before, @LazyOne explained that IIS will not serve unknown MIME types, and neither will the VS development server. I have now uploaded the site to an IIS 7 server, the MIME type for ogg is in place and when the site in accessed the server returns a 206 partial content (mozilla.org mentions that 206 responses are normal and expected for ogg files) and assessing the file directly works fine in Firefox (i.e. if you go to domain.com/music/file.ogg, it plays in the browser). and the file plays fine in the background if the autoplay attribute is set, but **it does not play via JavaScript**. Here is the JavaScript in question and relevant html:               audioMusic.volume = 0.15;          function playMusic(){            audioMusic.play();     }          function stopMusic(){         audioMusic.pause();     }      Relevant html:                             <title></title>                      on       off           <audio id="audioMusic" loop="loop" preload="auto">        <source src="/Music/music.ogg" type="audio/ogg" />        <source src="/Music/music.mp3" type="audio/mp3" />          </audio>                            More interesting facts:   * the playMusic() function is called in firefox, if you add an alert at the beginning it does off, but it is not able to execute: audioMusic.play()   * I have also tried document.getElementById("audioMusic").play();    * Both document.getElementById("audioMusic").play() and audioMusic.play() work in Chrome and IE, but not in firefox   * I am using Firefox 5.0.1 (the latest) **Question:** how to control the audio element via JavaScript in Firefox?


which product category to choose in magento

I am newbie in magento. I am creating a **product** that is basically a **video file**. I want that whenever the user clicks on that product he is asked to buy different file sizes for that video like HD version, Sd version. So I thought to create a simple prduct with custom options of file size. **But I want your suggestion that whether I should create it as a downloadable product, configurable or simple product with custom options.** Basically I am confused as it needs to be a **downloadable product** where the different sizes video files are located at server for download or it can be **simple** product also just click and buy the particular product of file size or it cabn be **configurable** also. Please suggest.Thanx in advance.

Assuming unique user names / logins, do I also need a unique userID number in the DB?

My users will login into a website using a login of their choosing, but which I will check against the DB to ensure unicity. Given this, should I also have a unique userID in the DB? This could be an autoincrement number and would be completely invisible to the users. Thanks, JDelage


90% of 'links to your site' disappeared in Google Webmaster Tools

I was going through Webmaster Tools and I noticed that under 'links to your site' there's only 40 links showing. Down from 700+ yesterday. I don't think it was anything to do with the quality of the sites linking in because some of them were quite high ranking blogs so I don't think it's Penguin related. This has happened to me once before on a previous site and after about a month or so they came back, so it's not something I'm super worried about, but it's really odd. Has anyone else experienced this? Or know why it happens? * * * Update - All links seem to have returned 20/2/13

joomla subscription ecommerce solution

I am using Joomla and want to implement a subscription based ecommerce solution. I started using VirtueMart and noticed its shortcomings regarding subscription based recurring items. Turns out Virtuemart can take its own plugins and I found something called SimSu which I don't want to pay for. I feel like I have taken a nuke to a knife fight, as I only need one or two subscription based products on this site. They will be recurring payments. Is anyone familiar with a solution for this issue?


server downtime solution?

I am managing a few sensitive websites, that need to be up and running 24/7 how ever I worked with many VPS and dedicated server providers over the time. The problem is that downtime is inevitable, at least for a few hours a year and my client is pinging the websites round the clock. Is there any solution like automatic switching DNS or hosting on 2 servers from 2 different providers and is there a way for syncing the data between servers before actual sinking.


What is difference between URI and URL

I have read these pages   * http://www.w3.org/TR/uri-clarification/   * http://www.damnhandy.com/2007/11/19/uri-vs-url-whats-the-difference/    I know basic about URL,URN,URI! and little on their difference! but the thing I cannot understand is in a page like: `http://www.bernzilla.com/item.php?id=100` which part is URL,URN and URI!   URI is whole part but URL and URN??   picture from wikipedia   ![](http://upload.wikimedia.org/wikipedia/commons/thumb/c/c3/URI_Euler_Diagram_no_lone_URIs.svg/180px- URI_Euler_Diagram_no_lone_URIs.svg.png) Edit: from w3c.org:   a URL is a type of URI that identifies a resource via a representation of its primary access mechanism (e.g., its network "location"), rather than by some other attributes it may have. from www.damnhandy.com:                 it is now considered incorrect to use URL when describing applications.      Now is id an attribute?what about application part? is php an application?


Does using spaces in a URL affect SEO?

When creating URLs for my website I need to use a space, for example `http://mydomain.com/start home` I've seen some sites using `+` or `-`, what are the advantages of using `space`, `+` and `-` (dashes) in SEO? What is better to use for URL formatting? Should I use `http://mydomain.com/start-home` or `http://mydomain.com/start+home`?

Bounce rate nearly 100% in Safari AND Firefox?

Our website has a bounce rate of nearly 100% in both Firefox and Safari, and around ~40% in all other browsers. The bounces span all versions of each browser and both operating systems. I cannot recreate any error in either browser on any of my computers, and I'm not getting any php errors on my server. Firebug isn't throwing any javascript errors. The most prevalent google result for Safari is that top sites is skewing the bounce rate. But this seems extreme, and the addition of firefox pretty much rules it out. This one really has me confused. I've been googling for weeks to no avail. Our home page bounce rate is very low across all browsers. Any insight whatsoever, including what types of errors would cause safari and firefox to respond identically to would be greatly appreciated.

How to handle redirects & http status codes at urls where a product becomes unavailable?

I have this use case that happens frequently: Lots of products for sale, periodically a percentage goes out of stock. A user still browses in on the old url, to a location where a product used to be. I want to redirect them to a search page, and notify them that the product is no longer available, and try to provide them with alternatives. At the same time, I want to notify automated services (search engines, shopping engines) that that specific product is gone, in order to prevent continued hits to the urls in question. What ways are there for gracefully handling this? Edit: I'm refactoring/recoding the site in custom php code. I also do have a dedicated 404 page, with links to places on the site, etc, but don't really want to duplicate the search page's functionality on the 404 page when a system is already in place in a different php script, and for most 404's I already have a more generic suggestion for alternatives.
