Expected Behavior

It's generally unclear how AI data scrapers choose which websites to crawl and how often to crawl them. They might choose to visits websites with a higher information density more frequently, depending on the type of AI models they're training. For example, it would make sense that an agent training an LLM (Large Language Model) would favor sites with a lot of regularly updating text content.

Should I Block ClaudeBot?

It's up to you. AI data scrapers usually download publicly available internet content, which is freely accessible by default. However, you might want to block them if you're concerned about attribution or how your creative work could be used in the resulting AI model.

How Do I Block ClaudeBot?

⚠️ Manual Robots.txt Edits Are Not Scalable
New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.

You can block ClaudeBot or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
