Do you publish an llms.txt — and does it say the right thing?

It is a short plain-text file that tells AI assistants what your business does and which pages matter. Check whether you have one, and read exactly what an assistant would read.

What llms.txt is, in plain terms

Websites have carried a small file called robots.txt for thirty years, telling search engines what to look at. llms.txt is the same idea for AI assistants: a short, human-readable file at the top of your site that says what you do and points at the pages worth reading.

It is a young convention. No assistant is obliged to read it, and some will not. But it costs almost nothing to publish, and it is one of the very few places where you get to state plainly, in your own words, what your business is — instead of hoping something guesses correctly from your homepage.

What a good one contains

What you actually do

One or two sentences a stranger would understand. Not your tagline — what you sell and to whom.

The pages that matter

A short list of links with a line each: pricing, what you offer, how to get started, how to reach you.

Who you serve — and who you do not

Countries, languages, any limits. Saying who you cannot help is what makes the rest believable.

Nothing stale

A price from two years ago is worse than no price. If you cannot keep it current, leave it out.
