Put the site name and a “My Dashboard (0)” entry in the top bar.\n\nBelow that is a filter bar whose categories are fixed as All / Traffic / Conversion / Retention, defaulting to “All”. The main body is a metric list with 20 items in total, distributed as: Traffic 7, Conversion 7, Retention 6.\n\nEach item must have a name, its category, a sampling cost, and a “Track” button. Sampling costs are assigned by position: item n = 50 + n × 15. Each item also has a rating; item 1 is 4.9, and each subsequent item is 0.2 lower than the previous one. The list is sorted by rating from high to low by default." |
