Website Health Check
llms.txt is a short Markdown file at your site's root that points AI tools to your most useful pages. We check whether you have one, and run a free full check of your site's speed, security, SEO and AI search readiness.

01What we check
We ask for /llms.txt on your site and check that it is a text file, not your site's normal page (some sites answer every address with their home page).
A valid file starts with a title line (# Your business) and usually a short summary and lists of links to your key pages.
Honestly, not much: few AI tools read llms.txt so far. It is worth 2 of the 100 points in our AI search readiness score, and a missing file is a warning, never a fail.
The same check reads what AI tools rely on today: crawler access, text without JavaScript, schema, headings, trust signals and your sitemap.
A # title with your business name, a one-line summary in a > quote, and Markdown lists of links to your main pages (services, pricing, contact, guides), each with a few words about it.
No. robots.txt says which crawlers may read your site and the sitemap lists your pages; llms.txt is an optional, human-written guide on top of them.
