What is ChatGPT-User?
A fetch triggered when a person asks ChatGPT about a URL or topic — closer to a visitor than a background indexer.
How this helps you show up
When this bot can load your page, the person asking gets an answer grounded in your actual content. That is direct exposure at the moment someone is curious about you.
If it cannot reach your page
The user still gets an answer, but your page is not in it. Treat it like turning away someone who clicked through from a chat.
