Start with the technical layer: check whether AI crawlers can actually read your pages — server-side rendering, no accidental robots.txt blocks — whether structured data and llms.txt are in place, and whether your core pages open with direct, quotable answers rather than marketing preamble. Then check the content layer: is there topical depth, consistent facts, and credible third-party corroboration for your key claims?
Kando built two free tools for exactly this — the GEO Technical Validator checks structured data, llms.txt, and semantics, and the Growth Audit Grader gives a broader SEO and AI-visibility score across a full site.
