llms.txt
llms.txt, llms.txt is a proposed plain-text file at the root of a website that offers AI systems a curated, easy-to-read guide to the site's most important content, an LLM-oriented cousin of robots.txt and sitemap.xml.
The idea is to hand models a clean map of what matters on your site, key pages, concise descriptions, in Markdown, so they can understand and represent you without wading through navigation and markup. Adoption is early and support varies by system.
It's worth knowing as part of the emerging AI-visibility toolkit, but it's not a silver bullet: no file makes a model recommend you if the broader signals aren't there. Treat it as a low-cost clarity aid alongside the fundamentals, structured data, authority, and a complete business profile.
Key points
- →A root-level Markdown guide to your site for LLMs.
- →Analogous to robots.txt / sitemap, but for AI comprehension.
- →Emerging and inconsistently supported, a complement, not a fix.
