AI Visibility & GEO Research
The 5W AI Visibility Index series ranks brands by citation share across the major AI answer engines — ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. Each index uses 5W's proprietary Generative Engine Optimization methodology to measure how a category surfaces inside generative AI, where brands win mention share, and where they disappear. Together, these indexes form the largest published library of category-level AI visibility benchmarks in U.S. communications. The canonical destination for category-level AI Visibility studies is the dedicated AI Visibility Index hub; this Research page links those studies for discovery alongside 5W's broader research library. Scoring rubric and prompt architecture: AI Visibility Index Methodology.
