Definition
ClaudeBot indexes the open web for Claude's training corpus. Blocking ClaudeBot removes you from future Claude training - which is the only meaningful Claude SEO lever, since Claude does not natively retrieve at inference.
Why it matters
ClaudeBot sits in the "Crawlers & infrastructure" layer of the AI search stack. Teams that handle it well get cited more, recommended more, and earn more of the AI-mediated revenue in their category. Teams that ignore it spend a year wondering why their content investment never moves the needle inside ChatGPT or Perplexity.
