llms.txt
llms.txt is a text file placed at a site's root that offers AI models a structured map of the content deemed important. It's an emerging standard, useful mainly as a positioning signal: to date, no major AI engine officially consumes it.
llms.txt is a text file, placed at a site's root, that presents language models with a structured, hierarchical version of important content. Inspired by robots.txt, it aims to guide AI toward your key pages. But we have to be honest about its status: it's an emerging standard, not yet adopted by the major engines.
What llms.txt really does
The available data is clear: among the domains most cited by AI, only a tiny minority has an llms.txt, and AI bot traffic to that file is negligible [À VALIDER]. John Mueller (Google) has even stated that no major AI system consumes it to date. In other words: it doesn't earn citations.
A concrete example
An agency can build a clean llms.txt listing its strategic pages. Today, that won't bring it any additional citations, but it costs two hours and prepares it for possible future adoption. It's a bet on optionality, not a priority.
Why it matters (and doesn't)
llms.txt is worth knowing about so you don't over-invest in it. The real levers of GEO lie elsewhere: schema markup, citable passages and GEO seeding. To prioritise what actually works, see our GEO agency.
llms.txt: worth creating for optionality, never as a citation lever. AI ranking is won elsewhere.
Questions fréquentes
Yes, for optionality, since the cost is almost nil. But have no illusions: to date, no major AI system consumes it to decide its citations. It's a positioning signal, not a ranking lever.
