Creating llms.txt

llms.txt is a short Markdown file in the root of your domain that gives AI systems a structured entry point into your key content.

Location and delivery

The file lives at https://your-domain.com/llms.txt and should be served as text/plain or text/markdown — not as an HTML page with a 200 status that is really a 404 error page.

Structure

Start with an H1 (the name), followed by a blockquote or paragraph with a one-sentence description. Then one or more H2 sections with Markdown link lists to your central pages, each with a short explanation.

Copy-ready skeleton

# Your company — > One sentence on what you offer. — ## Key pages — - [Product](URL): benefit in half a sentence — - [Pricing](URL): model in half a sentence — - [About](URL): who is behind it — ## Optional — - [Blog](URL): what you write about.

llms-full.txt

In addition, an llms-full.txt can bundle the full text content of the key pages in one file. Useful for documentation, less so for small company sites.

Realistic expectations

llms.txt is not a binding standard and is not evaluated by all systems. It replaces neither clean robots.txt rules nor server-side rendered content. It is a cheap extra signal, not a substitute for the basics.
