# GeoScore

> GeoScore is a free, open-source GEO (Generative Engine Optimization) audit tool. It scores any website 0-100 across 12 dimensions of AI search visibility, then generates fix files (llms.txt, robots.txt, JSON-LD schema) you can deploy immediately. Used to diagnose why some sites get cited by ChatGPT, Perplexity, and Claude while others don't.
