GA4's AI Assistant channel: how to see visits from ChatGPT, Gemini and other AI tools

What changed in GA4

Until this year, if someone clicked a link to your website inside ChatGPT, GA4 usually counted that visit as Referral. It sat in the same bucket as a link from a blog or a directory. If you wanted to see AI traffic on its own, you had to build a custom channel group with a long pattern of website names.

On 13 May 2026, Google added a new channel to the default channel group. In its What's new in Google Analytics page, Google says visits from chatbots such as ChatGPT, Gemini and Claude are now grouped under an AI Assistant channel. Search Engine Journal reported that property owners do not need to configure anything.

A "channel" in GA4 is simply a label for where a visit came from: Organic Search, Paid Search, Email, Social, and so on. The default channel group is the set of rules GA4 uses to give every visit one of those labels.

How the AI Assistant channel works

Google's default channel group help page lists the rules. When the website that sent the visit (the "referrer") matches Google's list of AI assistants, GA4 does three things:

• It sets the medium to ai-assistant.
• It sets the campaign to (ai-assistant).
• It places the visit in the AI Assistant channel.

So you can find this traffic in three places: the channel, the medium and the campaign. The simplest is to open Reports, then Acquisition, then Traffic acquisition, and look for the AI Assistant row in the session default channel group.

What it does not capture

This is the part most people miss. The new channel is useful, but it is not the full picture of how AI tools send you customers.

Google's own AI features are not included

The help page states that AI Assistant excludes Google's AI Overviews and AI Mode. Clicks from those stay inside Organic Search, mixed with normal Google results. If you want to understand AI visibility on Google itself, you need Search Console, not GA4.

Visits with no referrer go to Direct

Many people use ChatGPT or Gemini as phone apps. When a link opens from an app or in-app browser, the referrer is often lost. Search Engine Journal noted that this traffic still lands in Direct. GA4 has no way to know it came from an AI tool.

The list of AI tools keeps changing

Google has not published a full, fixed list of the assistants it recognises. A July 2026 Search Engine Journal analysis found the list had already shifted since launch, and that Perplexity traffic was not on it and still showed as Referral. The same article found that one source, chatgpt.com, could appear in AI Assistant, Referral and Unassigned at the same time.

Older data is not changed

The channel only tags visits from the point it went live. If you compare April with August, April will show almost no AI Assistant traffic. That is not real growth. It is the label arriving. Compare periods that are both after the change.

It counts clicks, not mentions

If ChatGPT recommends your shop and the person searches your name on Google later, that visit shows as Organic Search or Direct. The AI Assistant channel only sees the click from the chatbot itself.

How to read the numbers without fooling yourself

1. Look at the trend, not the size. For most small businesses AI traffic is still a small slice. The useful question is whether it grows month by month.
2. Check which pages AI visitors land on. Add landing page as a second dimension. This tells you which content AI tools find useful enough to link.
3. Look at key events. Do AI visitors book, call or buy? A small channel that converts well is worth more attention than a big one that does not.
4. Check Referral and Unassigned too. Search them for chatgpt, perplexity or copilot. Add those visits to your mental total.
5. Use complete periods. Compare two full months that both started after June 2026.

What this means for businesses in Cyprus and Greece

I see more and more people in Cyprus ask ChatGPT for "a good physio in Strovolos" or "where to buy a gaming laptop in Nicosia". When those answers include a link, you now have a simple way to see it in GA4, without any setup.

For local service businesses, such as the clinic sites I built in Nicosia, the numbers will be small at first. That is fine. Watch which pages get these visits. Often it is a clear service page or a page that answers a common question in plain words. That tells you what kind of content to write next.

For e-shops in Greece and Cyprus, check the landing pages from AI Assistant against your sales. If AI tools send people to category pages that are thin or out of date, fix those pages first. And remember that Google AI Mode traffic is hidden inside Organic Search, so read GA4 together with Search Console.
