GEO SEO AI Optimizer - Analysis Package
======================================

Generated: {datetime.now().strftime('%Y-%m-%d %H:%M:%S')}

This package contains the complete analysis results from the GEO SEO AI Optimizer tool.

Files Included:
- JSON file: Complete raw data in JSON format
- HTML file: Visual report for web viewing
- CSV file: Tabular data for spreadsheet analysis
- README.txt: This file

About GEO (Generative Engine Optimization):
GEO is the practice of optimizing content for AI-powered search engines and 
language models. Unlike traditional SEO, GEO focuses on:

- AI search visibility
- Query intent matching
- Conversational readiness
- Citation worthiness
- Semantic richness
- Context completeness

How to Use These Files:
1. Open the HTML file in a web browser for a visual report
2. Import the CSV file into Excel or Google Sheets for analysis
3. Use the JSON file for programmatic processing or integration

For more information about GEO optimization, visit the tool documentation.
