Read policy, evidence and uncertainty together

A successful fetch from AI Crawl Score means our generic client received a response. It does not establish how a verified crawler will be treated by your server or CDN. The crawler matrix interprets the page’s robots rules; it does not claim to observe real crawler visits.

Use the result to prioritize a review

Check failed findings first, then examine unknown or untested signals. Open each finding for its weight, evidence and recommended action. Keep deliberate exclusions intact on pages that should remain private or undiscoverable.

Frequently asked questions

Does passing this validator improve AI search rankings or citations?

No. This is a structure linter only. Google and major AI crawlers do not guarantee any use of llms.txt; there is no fabricated "AI readability score" and no ranking or citation guarantee.
