Expected Behavior
ClaudeBot crawls websites to build AI training datasets, and its operator decides which sites, how often, and how deep it goes. Expect broad sweeps that fetch far more pages per visit than a search crawler would, on an unpredictable schedule. Volume can run heavy while a collection pass is underway, then stop entirely.

Frequently Asked Questions
Should I Block ClaudeBot?
Block it if you want control over how your work trains AI models. ClaudeBot downloads your content into training datasets without attribution, compensation, or any promise of traffic back. The case for allowing it is reach, because models trained on your content can surface your brand in AI answers. Neither choice changes your Google rankings. For comparison, 20% of the top websites we track already have robots.txt rules for ClaudeBot.
Does ClaudeBot Follow Robots.txt Rules?
Yes. ClaudeBot is expected to follow robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms ClaudeBot actually follows it.
Does ClaudeBot Access Private Content?
ClaudeBot targets public content, but the boundary is not always respected. Some training data scrapers go after paywalled or gated pages when the operator wants that data. If a page loads without signing in, assume it can be collected.
Why Is ClaudeBot Visiting My Website?
Your content matched what Anthropic wants in a training dataset. ClaudeBot discovers pages mechanically, through links from other sites, sitemaps, and seed lists, not because anyone chose your site personally.
How Can I Tell if ClaudeBot Is Visiting My Website?
Agent Analytics tracks ClaudeBot visits and every other known AI agent, crawler, and scraper alongside it, then authenticates each visit against ClaudeBot's published verification method. You can also check your server logs for requests whose user agent string contains "ClaudeBot". Look for broad sweeps that fetch large numbers of pages in sequence. A log match is still not proof, because any bot can claim to be ClaudeBot.
