01What we check

What this check looks at.

Search crawlers

Googlebot, Bingbot and OAI-SearchBot (ChatGPT search). Blocking them keeps your pages out of search results and AI answers, so it fails the check.

AI answer crawlers

PerplexityBot, Claude-SearchBot and ChatGPT-User, which fetch pages when someone asks an AI tool a question. Blocking them is a warning.

Training-only crawlers

GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot collect data for training AI models. Blocking them is your choice: we list them and they cost no points.

Your firewall

We ask for your home page under the names of OAI-SearchBot and PerplexityBot. If your firewall or bot protection refuses those requests, it may turn the real crawlers away too.

02FAQ

Questions people ask.

The full tool and how it works: Website Health Check.

Should I block GPTBot?

That is your choice. GPTBot collects training data; blocking it does not keep you out of ChatGPT search, which uses OAI-SearchBot. Our check scores the search and answer crawlers, not the training ones.

Why might a crawler be blocked when robots.txt allows it?

Firewalls and bot protection (for example on Cloudflare) can refuse requests by name before robots.txt matters. That is why we also test with the crawlers' names.

Can you test from the crawlers' real addresses?

No. We send the requests from our own server, so a firewall that checks addresses may treat the real crawlers differently. The report says so when it matters.
