llms.txt
llms.txt is a proposed Markdown file that points AI tools toward a site's most useful LLM-readable pages and context.
llms.txt is a proposed file at the root of a website, similar in placement to robots.txt or sitemap.xml. Instead of controlling crawling or listing every URL, it gives AI tools a concise guide to the site's important pages and Markdown-friendly resources.
It should not be treated as a guaranteed ranking lever. Today, the safer use is practical: make the site's purpose, key pages, and clean reference material easier for agents and AI tools to find when they do look.
Know the words.
Let the agent do the work.
