llms.txt links resolve

What this check means

Samples the links in your llms.txt and checks that they resolve.

Why it matters

A broken link in llms.txt is worse than a broken link on a page. This is the file you offered as your curated map, so a system following it lands on nothing — and has no reason to believe the rest of the file is any more accurate.

How we detect it

We take up to ten links from your file, spread across its sections, and issue a HEAD request to each. Servers that refuse HEAD are not counted as broken. We deliberately sample rather than check everything, so an audit never becomes a crawl of your site.

How to fix it

Correct or remove the dead links, and regenerate llms.txt whenever the pages it points at move.

Check whether this applies to your site.
