llms.txt
A proposed text file that tells AI crawlers which content on your site to use, similar in spirit to robots.txt.
In depth
What it really means
llms.txt is a proposed standard: a plain text file at your site root that points AI systems to the content you want them to use and understand, in a clean, structured form. Think of it as a curated map for AI, alongside robots.txt and sitemaps.
Adoption is early and not universal, so treat it as a low-cost, forward-looking addition rather than a guaranteed ranking lever.
Best practices
- Add a clear llms.txt pointing to your most important content.
- Keep it simple and well-structured.
- Don’t rely on it alone; strong content and structure still matter most.
- Keep it updated as your key pages change.
- Pair it with clean, crawlable pages.
