Is ClaudeBot blocked on your site?
ClaudeBot is the Claude crawler that builds the index the model answers from. If your robots.txt blocks it, that engine cannot read your pages, and a page it cannot read is a page it can never cite.
Free, no sign-up. We fetch one public file and read it. Nothing is stored.
Questions
- What does ClaudeBot do?
- ClaudeBot is used by Claude. It builds the index the model answers from.
- Should I block ClaudeBot?
- Usually not. This crawler is how Claude reaches your pages when answering a question, so blocking it removes you from answers you could have been cited in.
- Is this check free?
- Yes, and there is no signup. We fetch one public file, robots.txt, and read the rules for this user-agent. You see the full result, including every failure we find.
