How to find AI assistant visits in GA4, Shopify and Search Console
A large publisher says Google referrals fell about 37%. Here is where AI visits show in GA4, Shopify and Search Console.
On November 9, 2026, Search Engine Journal reported that a large publisher said its Google search referrals fell about 37% year over year in the third quarter. Its CEO also cited a figure from Google Search Console: about 2.7 billion impressions for AI Overviews and AI Mode. By his estimates, that was nearly ten times the clicks his sites received from Google Search. That comparison is the part to read closely, because it does not measure a click-through rate.
Before you act on a number like that, check what the reports in your own accounts count.
AI assistant visits have their own channel in GA4
Since May 13, 2026, GA4 gives visits from AI assistants a channel of their own. When a visit's referrer matches a recognized AI Assistant, GA4 sets the medium to ai-assistant, sets the campaign to ai-assistant, and places the visit in the AI Assistant channel of the Default channel group. The channel covers sources like ChatGPT, Gemini, Deepseek, Copilot or Grok. The release notes and the Default channel group guide describe the rule.
The catch is recognition. An AI session that arrives without a referrer GA4 recognizes cannot match the rule, so it falls into Direct or Unassigned. Magnet made the same point in a July 16, 2026 write-up. The AI Assistant channel therefore shows the AI visits GA4 can identify, and nothing more.
Google's AI answers are counted in Organic Search
The Default channel group places visits from AI Overviews and AI Mode in Organic Search. The AI Assistant channel does not include them. Search Console counts them too. Google's guidance on AI features, dated December 10, 2025, says sites appearing in AI Overviews and AI Mode are included in overall search traffic, in the Performance report under the Web search type.
The generative AI report counts impressions, not visits
Google announced its Search Generative AI performance reports on June 3, 2026, and rolled them out to all websites by August 31, 2026. The announcement says they show impressions, pages, countries, devices and dates. Google's help page, as the news item describes it, says the report counts how many times links to a site appeared in AI Overviews and AI Mode. The publisher's CEO defined an impression the same way: "how many times a link to a page was shown inside generative AI features."
Clicks are the gap. Google's help page on clicks says a click on a link in an AI Overview or AI Mode counts toward a site's total click count. As of November 8, 2026, Google documents no separate AI click count, so AI clicks sit inside your normal Search clicks. The news item says the comparison sets AI feature impressions against all clicks from Search. Other sites with the report can build the same comparison, but it only sets AI impressions against all Search clicks.
What outside studies say about clicks
Neither study measures your own reports, so treat them as rough context. In Pew Research Center's March 2025 browsing data for 900 U.S. adults, people who met an AI summary clicked a traditional result in 8% of visits, against 15% without one. They clicked a source link inside the summary in 1% of visits. In Wisepops' State of traffic report, a sample of about 704 million sessions from April to June 2026 showed AI referrals at about 0.1% of sessions.
The sources read here do not state what ChatGPT, Perplexity, Claude or Copilot add to links or send as a referrer. They also do not state how many clicks Google's AI features send to a Shopify store, or how Shopify's own reports sort these visits. The generative AI reports show impressions and no click figure.
Three traps to avoid
- Reading the AI Assistant channel as all AI traffic. Visits with no recognized referrer land in Direct or Unassigned.
- Looking for AI Overviews and AI Mode visits in the AI Assistant channel. They sit in Organic Search.
- Looking for clicks in the generative AI report. It shows impressions, pages, countries, devices and dates.
What to do this week
- Open GA4 and check the AI Assistant channel in the Default channel group for the period you care about.
- Check Direct and Unassigned for the same period, so you know what the channel leaves out.
- Ask whoever runs your store how Shopify records referrals and whether your own links carry tags. Get the answer in writing.
- Open the Search Generative AI performance report in Search Console and note which pages get impressions. Do not divide those impressions by clicks.
- Keep the Performance report open for the same dates and watch its trend over time. Read it as a trend, never as a rate.
- Write down the one question you need answered, such as which pages AI answers send people to, and read every report against it.
Do you know which pages AI answers already point to? If not, that is the question to start with.
Where a technology department fits
Search is one source of organic growth, and the numbers that show it sit in GA4, Shopify and Search Console, each counting something different. Getting them to answer your questions means setting the tags and channels once, keeping them that way, and reading them the same way every month. We build and run the systems your customers find you with, and everything behind them. That is the work of a technology department: we map how your store runs, build the software that fits it, and run it after launch. Your next step is a discovery call.
