What we check

Technical SEO (HTTPS, title, description, canonical, viewport, H1, headings, language, Open Graph and robots), discovery (robots.txt, sitemap and AI crawlers) and GEO (llms.txt, JSON-LD, E-E-A-T, semantic HTML, raw HTML content, FAQ and dates).

Frequently asked questions

What is GEO?

Generative Engine Optimization is how you make content findable, understandable and citable by generative engines such as ChatGPT, Gemini, Perplexity and Google AI Overviews — on top of classic SEO.

Why does llms.txt matter?

llms.txt is a root-level file, in the spirit of robots.txt, that points language models to your most useful pages. It is still an emerging standard, but several tools already look for it.

Why can a JavaScript site fail this test?

Many AI crawlers do not run JavaScript. If the HTML ships empty and content only appears after React hydrates, the site is invisible to ChatGPT, Perplexity and similar tools. This audit reads raw HTML on purpose.
