Frequently Asked Questions
Should I Block ClaudeBot?
Block ClaudeBot if you want more control over whether your work is used for AI training. Allowing it may increase the chance that your brand appears in AI-generated answers, but either choice leaves traditional search rankings unchanged. For context, 22% of the top websites we track currently have robots.txt rules for ClaudeBot.
Does ClaudeBot Follow Robots.txt Rules?
Yes. ClaudeBot is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether ClaudeBot respects it.
Does ClaudeBot Access Private Content?
Not through legitimate access. ClaudeBot primarily targets public content, but some training-data scrapers also attempt to collect gated or paywalled pages. If content loads without authentication, assume it can be collected.
Why Is ClaudeBot Visiting My Website?
Your content matched the criteria Anthropic set for a training dataset. ClaudeBot typically discovers pages through external links, sitemaps, and seed lists rather than because someone selected your site individually.
How Can I Tell if ClaudeBot Is Visiting My Website?
Agent Analytics tracks visits from ClaudeBot and every other known AI agent, crawler, and scraper, then authenticates each visit using ClaudeBot's published verification method. You can also check your server logs for requests whose user-agent string contains "ClaudeBot". Look for high page counts, short gaps between requests, and deep traversal through linked content. A matching log entry alone is not proof because any bot can claim to be ClaudeBot.
