What do AI enginesfind at your root?

Two files decide what an AI engine can do with your site: robots.txt says who may come in, llms.txt says what is worth reading. We check both — and split the 26 crawlers into the 20 that power answer engines (and can cite you) from the 6 that only collect training data.

Two requests: /robots.txt and /llms.txt. We do not store the domain, and nothing is written to your site.

This is one check out of 126

robots.txt is the doorway. It is not the room.

Letting a crawler in does not make the page worth quoting. ProvenVisible runs 126 deterministic checks across SEO, answer-engine readiness and generative citation — each with the evidence attached and a line describing how the finding could be proven wrong.
