Control ClaudeBot Access
Allow ClaudeBot (Recommended)
To maximize your AI visibility, allow ClaudeBot to crawl your entire site:
# robots.txt User-agent: ClaudeBot Allow: /
Block ClaudeBot (If Needed)
To completely block ClaudeBot from crawling your site:
# robots.txt User-agent: ClaudeBot Disallow: /
Consider the Trade-off
Blocking ClaudeBot means your content won't appear in Claude AI responses, potentially reducing your AI search visibility.
