llms.txt is reachable

What this check means

Checks whether a file is served at /llms.txt on your domain root.

Why it matters

llms.txt is a short, curated map of your site written for machines. Without one, an AI system has to crawl and infer your structure from raw pages — which is slower, lossier, and entirely at its discretion which pages it reads.

How we detect it

We request https://yourdomain/llms.txt and require a 2xx response whose body is not an HTML page. Single-page apps often answer any unknown path with their own HTML shell; that is not a file, and we do not count it as one.

How to fix it

Publish a plain-text Markdown file at /llms.txt with an H1 title, a one-line blockquote summary, and H2 sections listing your most important pages as links.
