llms.txt: what it is and how to add it to your website

llms.txt is a plain-text (Markdown) file placed at the root of your site, for example yoursite.com/llms.txt. It gives large language models a short, curated map of your most important content.

What to include

• A one-line description of your business
• Links to your key pages: product, pricing, docs, best guides
• One short sentence describing each link

Example

# Your Brand
> One sentence about what you do and who you serve.

## Key pages
- [Pricing](https://yoursite.com/pricing): plans and costs
- [Guide to X](https://yoursite.com/blog/x): how X works

Does it guarantee citations?

No. Support for llms.txt varies between AI tools, so treat it as a low-effort helper, not a magic switch. Combine it with strong content, schema markup and open crawler access.
