How do I allow ChatGPT-User in robots.txt?

Add these lines to your robots.txt: User-agent: ChatGPT-User Allow: /

Is your site blocking ChatGPT-User?

ChatGPT-User is the crawler ChatGPT uses to open a page when a person asks it to. Check your site now: we read your robots.txt exactly as ChatGPT-User must, ask your server as each AI crawler, and look at your product pages.

Does blocking it hurt?

Opens pages when a person asks Blocking ChatGPT-User stops ChatGPT from opening your pages when a person asks about them, so it answers without your own page.

In our research, 1% of 2,159 online shops block ChatGPT-User in robots.txt. See the research.

Allow or block it in robots.txt

OpenAI says robots.txt rules may not apply to ChatGPT-User, because it acts for a person. A server or firewall block still stops it.

To let it in (add to your robots.txt, at yourshop.com/robots.txt):

User-agent: ChatGPT-User
Allow: /

To keep it out:

User-agent: ChatGPT-User
Disallow: /

A more specific group wins: if your robots.txt also has a group for ChatGPT-User, 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.

Where this comes from

OpenAI’s own documentation: developers.openai.com. OpenAI: triggered by user requests; robots.txt rules may not apply; not used to decide what appears in search.
