LLMs.txt checker FAQ

What does this llms.txt checker test?
It checks whether your root domain exposes /llms.txt, /robots.txt, and /sitemap.xml. These are practical AI crawler hygiene signals, not a complete ranking audit.
Is a missing llms.txt an SEO error?
No. llms.txt is still an emerging convention. A missing file is not the same as a technical SEO error, but adding one can make your priority pages and source facts easier to maintain for AI visibility work.
Can this checker see whether ChatGPT cites my site?
This page checks crawl-readiness files. Use the AIRanked AI visibility checker for brand mentions, ChatGPT visibility, Perplexity citations, and competitor share-of-voice.
