01 The spec

What a valid llms.txt looks like

The llmstxt.org spec defines a strict, simple structure - this generator follows it exactly:

  1. An H1 with the site or project name - the only required element.
  2. A blockquote right after, summarising what the site is.
  3. Optional plain paragraphs with more detail (no headings).
  4. One or more H2 "file list" sections, each entry formatted - [Name](url): description.
  5. An optional ## Optional section - links an AI may skip when context is tight.

Companion files you can add later: /llms-full.txt (the full expanded content in one file) and .md versions of your HTML pages served at the same URL + .md.

02 Why it matters

Cheap insurance for the agentic web

Be honest about llms.txt: it's a proposal, not an established ranking factor. Google has publicly said it doesn't use it. A study of 37,894 AI-cited domains found no measurable citation difference between sites that had one and sites that didn't. So don't expect it to move your ChatGPT citations on its own.

That said, it costs 60 seconds. The agentic-browsing layer, ChatGPT's browsing, Claude, Perplexity, is exactly the audience it's designed for. Ship it as low-cost insurance, then put your real effort into the things that are proven to work: statistics, structure, and Bing indexing.

FAQ

Frequently asked questions

What is llms.txt?
llms.txt is a proposed standard (by Jeremy Howard, at llmstxt.org) - a Markdown file served at yourdomain.com/llms.txt that gives AI models a curated map of your most important pages, so they can understand your site without crawling everything.
Does llms.txt actually work yet?
Honestly: it's early and unproven. Google has said it doesn't use llms.txt. One 37,894-domain study found no measurable citation lift from having one. But it takes 60 seconds to add, and ChatGPT, Claude, and Perplexity's agentic browsing may use it. Treat it as cheap insurance, not a magic bullet.
Where do I put the file?
Upload it to your web root so it resolves at https://yourdomain.com/llms.txt. On most static hosts that means the public/ or root folder; on WordPress, the site root.
What is llms-full.txt?
A companion convention: a single file containing the full expanded content of your key pages (not just links), for models that want everything in one fetch. Generate the linked llms.txt first - it's the required file.
