What is llms.txt and Why It Matters
llms.txt is a plain-text file at your site’s root that summarizes your site for large language models. It gives AI crawlers a curated, machine-readable map of what your site is about and which pages matter, much like robots.txt does for search crawlers.
What it contains
A concise description of your organization, your key pages with links, and optionally links to detailed markdown files. It is designed for AI consumption, not humans.
Why it helps GEO
When an AI crawler reads your llms.txt, it can understand and cite your content more accurately, improving your chances of being recommended.
How to implement it
Publish an llms.txt at your domain root with a clear summary and links to your most important pages, then keep it updated.
