Does blocking it hurt?
AI search and answers Blocking Claude-SearchBot keeps your shop out of Claude search: your pages can't be read there, so they can't be shown or recommended.
In our research, <1% of 2,159 online shops block Claude-SearchBot in robots.txt. See the research.
Allow or block it in robots.txt
Anthropic says Claude-SearchBot follows robots.txt, so the lines below decide whether it reads your shop.
To let it in (add to your robots.txt, at yourshop.com/robots.txt):
User-agent: Claude-SearchBot Allow: /
To keep it out:
User-agent: Claude-SearchBot Disallow: /
A more specific group wins: if your robots.txt also has a group for Claude-SearchBot, that group decides, not the “User-agent: *” rules. Our check reads it the same way (RFC 9309).
Other places it gets blocked
- Cloudflare. Cloudflare has blocked AI crawlers by default on new sites since July 2025, and it can also write your robots.txt for you. If your site uses Cloudflare, check its AI crawler settings first (MIT Technology Review).
- Security plugins and firewalls. WordPress security plugins and host firewalls sometimes refuse crawlers they don’t recognise, even when robots.txt allows them. Our check asks your server as each crawler and shows any refusal.
