# HowsMyGEO > HowsMyGEO (howsmygeo.com) is a website audit tool that scores any URL on two axes: traditional SEO (14 checks, /100) and GEO — Generative Engine Optimization (7 checks, /100). GEO measures whether AI answer engines such as ChatGPT, Claude, Perplexity and Google AI Overviews can crawl, read and cite a site: robots.txt access for GPTBot, ClaudeBot, PerplexityBot, Google-Extended and CCBot; llms.txt presence; content extractability from server HTML; answer-shaped content; factual density; author/entity signals; and freshness. Headline scores are free; the full report with prioritised fixes is a one-time $5.99 (USD) purchase. ## Key pages - [Methodology](https://howsmygeo.com/methodology): Every check and its exact weight in the 100-point SEO and GEO scores, plus how measurements are taken.
