Only 11% of domains are cited by BOTH ChatGPT and Google AI Overviews for the same query. Each AI search platform uses different indexes, ranking logic, and source preferences. Platform-specific optimization is foundational to any serious GEO strategy.

How to Use

Collect target URL and the site's primary topic/industry
Open platforms.md (this skill directory) — it holds the 5 platform sections, each with How X Selects Sources rules + 10-item optimization checklist + 0-100 scoring rubric
Run each platform's checklist against the site
Score each platform on its rubric (0-100)
Generate GEO-PLATFORM-OPTIMIZATION.md using the output template below

Full rules + checklists + rubrics live in platforms.md:

Google AI Overviews (AIO) — top-10 organic gateway, question-headed Q&A, tables/lists, FAQ pattern
