In one sentence
ClaudeBot is the user agent of Anthropic's web crawler, which Anthropic documents as collecting public web content that may be used to train its Claude models.
What it means
Anthropic documents other user agents too, including ones for fetching pages on behalf of a user and for search. As with other vendors, each can be allowed or blocked on its own in robots.txt.
Anthropic says ClaudeBot respects robots.txt rules, including crawl-delay. Because Claude answers often lean on trained knowledge, long-term consistency of what the web says about your brand matters as much as any single page.
What to do about it
Check that your robots.txt does not block ClaudeBot by accident through a broad rule. Verify with the AI crawler access checker, and read Anthropic's current documentation for exact user agent names, since they change.
If you block training but want to be found, keep the agents that fetch pages for users and search allowed. Then confirm the effect by tracking Claude answers over the following weeks, rather than assuming.
