How do I see in GA4 how many visits come from ChatGPT?
Direct Answer
According to Google Analytics Help, the traffic acquisition report shows where new and returning users come from, and the Session source / medium dimension breaks each session down by its origin and channel. A referral link clicked inside an AI assistant’s answer behaves in GA4 like any other referral: the domain the click came from shows up as the source. Practically, that means checking for domains such as chatgpt.com or perplexity.ai inside that dimension, the same way you would check for any other referring site.
The traffic exists and is growing elsewhere
Similarweb data reported by PPC Land shows that visits from ChatGPT to news sites went from fewer than 1 million between January and May 2024 to more than 25 million in the same period of 2025, while Google searches ending with no click rose from 56% to nearly 69% over the same window. That data is about news sites, not B2B, and should be read as evidence of a channel that exists and is growing, not as your own traffic number.
Without checking your own GA4 property, an industrial company has no way to know whether that growth already reaches it or not. Measuring it is the only way to replace a guess with a number.

Where to Click
What this measurement does not show
This method only counts visits from a click on a link the assistant offered. It does not count the buyer who read an answer, never clicked, and later searched your company name directly or called the number they found there — that path shows up in GA4 as direct or organic traffic, with no trace of the assistant that started it. The same Pew Research Center study behind this hub found that clicking a link cited inside an AI summary happened in only 1% of visits to a page with a summary, so a small number here should not be read as a small effect overall.
Also watch for assistants that browse without leaving a referral trail: the absence of a domain in the report is not proof that no buyer used an assistant, only proof that no click carried a referrer this way.
Track it monthly, do not judge it by one snapshot
Whether the number is zero or already meaningful, the useful move is the same: save this view and read it every month, the same way you already read Google Ads and organic search. A rising trend line here is the earliest evidence that AI-assisted research is reaching your specific buyers, months before it would show up in any general survey.
