AI search fix
ClaudeBot blocked — how to fix it
When ClaudeBot is blocked, Anthropic's crawler cannot fetch your public HTML for Claude-related retrieval. Blocks typically come from robots.txt disallow rules, SEO plugin templates, or Cloudflare WAF challenges. Add an explicit Allow section for ClaudeBot in robots.txt, align CDN skip rules, and confirm HTTP 200 on priority URLs in logs. Unblocking improves crawl eligibility; it does not guarantee Claude will cite your site.
After fixes, compare CMS robots editor output with the live robots.txt browsers and crawlers fetch — staging and production often diverge.
Unblock ClaudeBot
- Review live robots.txt for disallow affecting ClaudeBot.

- Re-test after Wordfence or security plugin updates.
