FAQ

Does llms.txt control AI crawler access?

No. It is a voluntary content-discovery file. Crawler permissions still belong in robots.txt and applicable HTTP controls.

Does publishing llms.txt guarantee AI citations?

No. It can make important content easier to discover, but citations still depend on content quality, evidence, relevance, accessibility, and the behavior of each AI system.
