What Is llms.txt? The File That Points AI to Your Best Pages

Updated June 19, 2026

llms.txt is a newer idea borrowed from robots.txt: a simple text file that points AI assistants to your most important pages and explains, in plain language, what your site is about. It’s optional and still emerging — but very few sites have one, which makes it an easy way to get ahead.

What it is

A Markdown file at yoursite.com/llms.txt. Where robots.txt says what crawlers may read, llms.txt says what’s worth reading. It’s a short, curated map for AI: your key pages, in order of importance, each with a one-line description.

Why it might help

• It hands AI a clean summary instead of making it guess from your navigation.
• It highlights your best pages, so they’re more likely to be used.
• It’s quick to add and can’t hurt.

A fair caveat: llms.txt is a proposed convention, not an official standard, and support varies between AI tools. Treat it as a low-cost bonus, not a magic switch.

A minimal example

# Your Company

> One sentence describing what you do.

Keep it short, link only to pages that are already readable (see JavaScript and AI crawlers), and write clear descriptions.

How to add it

1. Create a file named llms.txt.
2. Add your site name, a one-line summary, and a list of key links with descriptions.
3. Upload it to the root of your site so it loads at /llms.txt.
4. Update it when your important pages change.

The bottom line

llms.txt won’t replace the fundamentals from our GEO overview — being readable, crawlable, and well-structured. But as a quick, optional extra that most sites skip, it’s a small edge worth taking.
