SEO and AI visibility
SEO and AI visibility
llms.txt is a proposed text file in your site's root with a concise overview of your key pages, aimed at language models.
It's an open proposal, not a standard every AI provider supports. The idea: just as robots.txt guides crawlers, llms.txt gives an AI tool quick context on what your site is and where the core sits.
The effort is small and the risk zero, but don't expect visibility from it by itself. Anything you notice comes from the content it points to.
