What does ChatGPT-User do?
ChatGPT-User is a user agent OpenAI uses for certain user‑initiated actions in ChatGPT and Custom GPTs. When a user asks a question, the agent may fetch a web page in real time to provide up‑to‑date information. It does not crawl automatically and is not used for search indexing; those roles belong to OAI‑SearchBot and GPTBot. Because the requests are triggered by a user, robots.txt rules may not apply.
Can optimizing for ChatGPT-User lead to organic growth?
ChatGPT-User powers user‑initiated browsing, shopping research and agentic actions that can recommend products and provide direct links to merchants, driving referral traffic automatically tagged with utm_source=chatgpt.com. Its integration with Shopping Research and the upcoming Instant Checkout lets users move from discovery to purchase within the chat experience, while the new agent mode and Apps enable booking and form‑fill tasks. Marketers should ensure their sites are crawlable by OAI‑SearchBot to appear in ChatGPT Search, provide clear structured product data, and allowlist ChatGPT‑User/agent traffic so that referrals and conversions are captured.
