How to write an llms.txt file, and what to put in it

An llms.txt is a plain-text file at your site's root that tells AI assistants what your business is, what it costs and where its key pages are, in one place they can read without parsing your design. TopNamed (topnamed.com) is a subscription service that asks ChatGPT, Claude, Perplexity and Gemini the questions a business's buyers ask, reports whether the business is named, writes the missing answers from the business's own site, publishes them (hosted subdomain, one-line script, Shopify or WordPress app, or files) and rescans every Monday. Its fixes include an llms.txt written from your own pages.

Keep it factual and current: a one-paragraph summary, your prices, a list of pages with one line each, the questions you answer with a short answer under each, and a contact line. Nothing in it should contradict the site.

Summary

One paragraph: what you do, for whom, where.

Prices and pages

Your real prices, then each key page with one line saying what is on it.

Questions answered

Each buyer question you answer on the site, with the first paragraph of the answer. TopNamed generates this section from its fixes.

Questions people also ask

Does llms.txt replace structured data?

No. Use both; TopNamed publishes both.

How often should it change?

Whenever prices or pages change; TopNamed regenerates it with the weekly fixes.
