llms.txt and business verification

A hint file says what to read on your site. A verification file says who attested the facts. You want both. They are not the same document.

Published 24 August 2026

First-party hints and third-party records get mashed into one slide in sales decks. Keep them apart or you will pay for the same work twice and still look unfinished.

On your domain

llms.txt, Organization markup, a footer with the real name, a badge that points at the public file. That is what a crawler should trip over in the first second.

Off your domain

A registry page and a JSON twin that do not depend on your theme. Silver records the website connection after the supported check. Gold is $297/year for a fuller owner-managed identity with supporting sources. The hash is the integrity check, not the government seal.

If you only ship llms.txt, you published a map of a house you have not shown anyone the deed to. If you only ship a registry file and the site is a maze, you published a deed to a house the crawler cannot enter.

Read why this exists. Check a name in the registry. Or start with a free check. Gold is $297/year for a fuller owner-managed identity with supporting sources.

FAQ

Which should I do first?
Prove the website, then put the badge and the hint on it. The file without the site is half a product.

Can I host the JSON on my own domain only?
You should also host facts on your domain. The registry copy is the third-party twin.
