What is llms.txt?

llms.txt is a plain-text file you place at the root of your site (served at /llms.txt) that tells AI crawlers and answer engines what your site is about and which pages matter most. Think of it as a robots.txt for large language models: where robots.txt says what crawlers can access, llms.txt says what your site is, in clean Markdown that models parse easily.

It's an emerging standard, and most sites still don't have one, which is exactly why adding it now is a cheap edge for being understood (and cited) by ChatGPT, Claude, Perplexity, and Google's AI Overviews.

How to use your llms.txt

  1. Fill in your site name, a one-line summary, and your most important pages above.
  2. Click Download to save the llms.txt file.
  3. Upload it to your site root so it's reachable at https://yourdomain.com/llms.txt. On most hosts that means dropping it in your public/ (or static) folder.
  4. Visit /llms.txt in a browser to confirm it loads as plain text.

Tip: keep it in sync with your sitemap. If you add or rename important pages, update llms.txt too, stale links help no one.

What makes a good llms.txt?

  • A clear one-line summary (the > blockquote), the single most important line.
  • Only your best pages, each with a short, honest description. Quality over quantity.
  • Absolute URLs so a model can follow them without guessing your domain.

FAQ

Where do I put the llms.txt file?

At your site's root, served at /llms.txt. For most static hosts and frameworks that means your public/ or static directory; on a framework like Next.js you can also generate it from a route. The file must return plain text.

Is llms.txt the same as robots.txt?

No. robots.txt controls crawler access; llms.txt describes your site for language models. They complement each other, you want both, and you want neither to block AI crawlers if your goal is to be cited.

Does llms.txt guarantee my site gets cited by AI?

No single file guarantees citation. llms.txt makes your site easier to understand, which helps, alongside clean structure, a sitemap, and not blocking AI crawlers. Run the AEO/GEO Readiness Checker to see your whole picture.
