What do AI agents get from your site?

The probe fetches your home page and up to three other pages as a normal browser and as 9 named crawlers and AI agents, then shows what each one got.

How it works

• Each request uses the agent's documented User-Agent with PosternaProbe/0.1 added, and is signed with Posterna's own key, so your logs show it was us.
• It reads your robots.txt first. Pages that robots.txt closes to PosternaProbe are not fetched, and the report says so.
• Two requests at a time, with a pause between them: about 40 requests in all.
• It keeps status codes, sizes and fingerprints (SHA-256), never page contents. Results are cached for an hour, and anyone with the report link can see it.
• The requests come from Posterna's servers, not from the agents. Sites that check agents by IP address or signature will rightly treat them as unverified. What we store.
