What is ChatGPT Agent?
ChatGPT Agent is an AI agent created by OpenAI that can use a web browser. It can intelligently navigate and interact with websites to complete multi-step tasks on behalf of a human user. Agent Analytics can track when it visits your website.
Category
Expected Behavior
ChatGPT Agent controls a real browser, so expect it to load pages, run JavaScript, keep cookies, and move through multi step flows the way a person would. Its path through your site follows whatever task it was given rather than a fixed crawl order, so visits look irregular. Sessions can pause on a page while the agent processes content, then jump somewhere unexpected.

Disallow: /Frequently Asked Questions
Should I Block ChatGPT Agent?
Usually no. ChatGPT Agent browses on behalf of a real person who is trying to read, compare, or buy something on your site. Blocking it turns away that person, not a bot farm, and they will finish the task on a competitor's site instead. Blocking it has no effect on your search rankings. For comparison, 1% of the top websites we track already have robots.txt rules for ChatGPT Agent.
Does ChatGPT Agent Respect Robots.txt?
No. ChatGPT Agent is not expected to honor robots.txt, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.
Does ChatGPT Agent Access Private Content?
It can if a user gives it access. ChatGPT Agent operates a real browser session, so if someone signs in to your site through it, it sees whatever that account sees. Without credentials, it reaches only what any anonymous visitor can reach.
Why Is ChatGPT Agent Visiting My Website?
Someone gave ChatGPT Agent a task your site can help complete, like researching a product, comparing options, or filling out a form. It reached you through links and search results, the same way a person would.
How Can I Tell if ChatGPT Agent Is Visiting My Website?
Agent Analytics tracks ChatGPT Agent visits and every other known AI agent, crawler, and scraper alongside it, then authenticates each visit against ChatGPT Agent's published verification method. You can also check your server logs for requests whose user agent string contains "ChatGPT Agent". Look for sessions that browse like a person but move through pages faster than one. A log match is still not proof, because any bot can claim to be ChatGPT Agent.
