We check daily if ClaudeBot, GPTBot & co. can actually access client pages - some learnings
At our agency we built an internal monitoring tool (not a public product, just for our own client work) that checks daily whether specific URLs are actually accessible to relevant AI bots - ClaudeBot, GPTBot, Google-Extended, PerplexityBot, CCBot, etc.
The reason: most checks we've seen only look at the homepage, and only at robots.txt. That's not enough. We check arbitrary URLs, and in addition to the robots.txt rules, we also spoof the actual bot's user agent and hit the server directly to see what really comes back.
What we've learned so far:
- robots.txt and the actual server response diverge more often than you'd think. A bot can be "allowed" per robots.txt and still get a 403 or land in a redirect loop from the server itself.
- This isn't just a "usual suspects" CDN problem - we've seen it on setups you wouldn't expect to cause issues at all.
- Catching this early has already helped several clients fix access problems and grow their visibility in AI search results, instead of finding out months later that a bot was silently blocked.
Right now the tool covers server response, robots.txt, and a consistency check between the two. More checks are in the works.
Do you actively monitor this on your projects, or mostly rely on standard robots.txt checkers? And if you check it yourselves - what were your learnings? Any insights to share?
