Why Is ChatGPT-User Visiting My Website?
A user asked OpenAI's assistant a question your page could help answer. ChatGPT-User retrieved the page to support its response, often with a citation linking back to your site.
Should I Block ChatGPT-User?
Usually not. Blocking ChatGPT-User can keep your pages out of AI-generated answers and eliminate potential citation traffic. It does not improve traditional search rankings. For context, 15% of the top websites we track currently have robots.txt rules for ChatGPT-User.
How Do I Block ChatGPT-User Using Robots.txt?
Add this rule to your robots.txt file to block ChatGPT-User from accessing your website, or use Automatic Robots.txt to block all AI assistants at once. You can customize which pages are blocked by swapping out / for a different path.

Frequently Asked Questions
What Traffic Patterns Should I Expect From ChatGPT-User?
ChatGPT-User makes isolated, on-demand requests rather than crawling your site. Traffic follows user demand, ranging from sporadic fetches to steady visits for a popular assistant.
Does ChatGPT-User Follow Robots.txt Rules?
ChatGPT-User is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether ChatGPT-User respects it.
Is ChatGPT-User Used for AI Model Training?
Not ordinarily. ChatGPT-User is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking ChatGPT-User Affect AI Search or Citations?
Yes, for requests handled by ChatGPT-User. Blocking it can prevent the assistant from retrieving your pages for an answer or linking to them, but a separate crawler may control automatic AI search indexing.
Does ChatGPT-User Access Private Content?
Not ordinarily. ChatGPT-User fetches pages as an anonymous visitor without a stored login. Content protected by a paywall or login remains out of reach.
How Can I Verify a Request From ChatGPT-User?
Agent Analytics tracks visits from ChatGPT-User and every other known AI agent, crawler, and scraper, then authenticates each visit using ChatGPT-User's published verification method. You can also check your server logs for requests whose user-agent string contains "ChatGPT-User". Look for a single-page request with no follow-up navigation. A matching log entry alone is not proof because any bot can claim to be ChatGPT-User.
How Is ChatGPT-User Different From Other OpenAI Agents?
