- Which GA4 channel picks up readers who arrive from ChatGPT, Gemini and other AI tools
- The AI traffic the default AI Assistant channel misses: Google's AI Overviews, and visits that arrive with no referrer
- How to check your sources, build your own channel group, and audit robots.txt
Quick answers
- Q: Can I see readers who came from ChatGPT in GA4?
- A: Yes. As of October 2026, Google's help pages list an AI Assistant channel in the default channel group, covering sources such as ChatGPT, Gemini and Copilot. Visits that arrive without a referrer land in Direct instead, so the channel is not the whole picture.
- Q: Do visits from Google's AI Overviews count as AI Assistant?
- A: No. Google's help pages exclude AI Overviews and AI Mode from AI Assistant and count them under Organic Search. They are mixed into your search numbers.

Quiet search does not mean nobody is reading
When I wrote about five straight weeks with zero search traffic, one thing kept nagging at me. Search numbers were shrinking, yet readers had not disappeared altogether.
Some of them never touch a search box. They ask ChatGPT or Gemini something like "how do FX affiliate commissions work?" and click a source link under the answer. If you only watch search numbers, those readers are invisible.
So where does GA4 put them? Roughly half land in AI Assistant. The rest are scattered elsewhere. Here is how that sorting works and how to check it in your own account.
Where AI readers end up in GA4
GA4 groups visits by where they came from, in what it calls channels. As of October 2026, Google's help pages list an AI Assistant channel in the default channel group. Visits from ChatGPT, Gemini, DeepSeek, Copilot, Grok and similar tools are filed there.
Not every AI visit makes it in, though. There are three main places they leak to.
1. Google's AI Overviews and AI Mode → Organic Search
Readers who click through from the AI summary at the top of Google results (AI Overviews), or from AI Mode, are not counted as AI Assistant. Google's help pages exclude both from that channel and include them in Organic Search. Search Console likewise counts a click on a link inside these features as a regular search click.
2. Visits with no referrer → Direct
Someone opens your link inside an app, or copies a URL out of an AI answer and pastes it into a browser. Visits like these can arrive without any information about where they came from. GA4 files them as Direct, and the AI origin is lost.
3. AI tools not on Google's list → Referral
Google has not published the full list of AI tools it sorts into AI Assistant. Visits from a service that is not named in the help pages may be sitting in ordinary Referral.
Three checks you can run in your own GA4
There are three steps. All of them are free and take about ten minutes.
Open Reports → Acquisition → Traffic acquisition and set the first column to Session default channel group. If you see an AI Assistant row, that is the AI traffic GA4 has sorted for you. Use a range longer than 28 days. While numbers are small, week-to-week changes mean very little.
Switch the same column to Session source / medium and look for chatgpt.com, gemini.google.com, perplexity.ai, claude.ai, copilot.microsoft.com and similar. Any AI source that is not in AI Assistant is the third kind of leak above. Links from ChatGPT sometimes arrive with utm_source=chatgpt.com on the end of the URL, so watch for that name in the source column too.
Go to Admin → Data display → Channel groups, copy the default group, and add a new channel. Set the condition to Source matches regex and list the sources you found in step 2. Place this channel above Referral. GA4 checks channels from the top down and files each visit under the first one that matches. A standard property allows two custom groups, and a custom group applies to past data as well.
The regex can look something like this. Add or remove names to match what actually shows up in your own source report.
chatgpt\.com|chat\.openai\.com|gemini\.google\.com|perplexity\.ai|claude\.ai|copilot\.microsoft\.com
Once you know the channel, go one step further and see which articles AI readers land on, in Pages and screens or a similar report. The articles AI tools point to are not always the ones search sends people to. Many people have a hunch that pieces answering a question in one line, or laying out numbered steps, get picked up more often. Your own numbers are the only way to test that. If you track sign-up button clicks, line them up by landing page. For reading small numbers, see how to read numbers below one a day.
Getting found: check robots.txt
An AI tool can only recommend your article if its search crawler is allowed to read it. Two OpenAI crawlers are easy to mix up:
- OAI-SearchBot: used to surface websites in ChatGPT's search features. OpenAI says sites that opt out of it will not be shown in ChatGPT search answers.
- GPTBot: collects content that may be used to train AI models.
OpenAI says the two settings are independent, so you can appear in search while keeping your content out of training. It also notes that a robots.txt change can take about 24 hours to reach its search systems.
Kingfin's own robots.txt allows OAI-SearchBot, because we want to be cited in AI search. On your own blog, open /robots.txt once and make sure a theme or plugin default is not quietly blocking AI crawlers across the board.
Do not put a bold promise like "guaranteed income" or "¥100,000 a month, fast" at the top of an article in the hope that AI tools will quote it. If an AI answer cites you, that overstatement goes straight to the reader. When you promote financial or investment services, overstatement can also run into advertising and consumer-protection rules. Write for AI readers to the same standard you write for people.
