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.
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, 23% of the top websites we track currently have robots.txt rules for ClaudeBot.
How Do I Block ClaudeBot Using Robots.txt?
Add this rule to your robots.txt file to block ClaudeBot from accessing your website, or use Automatic Robots.txt to block all AI data scrapers at once. You can customize which pages are blocked by swapping out / for a different path.

Frequently Asked Questions
What Traffic Patterns Should I Expect From ClaudeBot?
ClaudeBot tends to make broad, high-volume sweeps across many pages. Timing is unpredictable: traffic may remain heavy throughout a collection pass, then stop entirely.
Does ClaudeBot Follow Robots.txt Rules?
ClaudeBot is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether ClaudeBot respects it.
Is ClaudeBot Used for AI Model Training?
Yes. ClaudeBot collects web content for use in AI training datasets. Blocking it limits future collection but cannot remove content that was collected previously.
Does Blocking ClaudeBot Affect AI Search or Citations?
Not directly. Blocking ClaudeBot limits collection for AI training rather than controlling a live AI search index or citation system.
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.
How Can I Verify a Request From ClaudeBot?
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.
How Is ClaudeBot Different From Other Anthropic Agents?
