## In short

- AI assistants that link to you usually show up in GA4 as referral traffic from their own domains, for example chatgpt.com.
- Use Traffic acquisition with Session source, filter with one regex for all assistants, or build an “AI assistants” channel group.
- Some AI visits arrive without a referrer and look like Direct. Treat the numbers as a floor, and pair them with your prompt baseline.

## Where AI visits show up

When ChatGPT, Perplexity, Claude, Gemini or Copilot link to your page and someone clicks, the visit usually arrives with the assistant’s domain as its source: `chatgpt.com`, `perplexity.ai`, `claude.ai`, `gemini.google.com`, `copilot.microsoft.com`. In GA4 that is referral traffic. You will also often see `utm_source=chatgpt.com` on ChatGPT links; that is observed behavior in analytics, not something OpenAI documents.

## 1. The quick check (2 min)

1. In GA4, open **Reports → Acquisition → Traffic acquisition**.[^ga4]
2. Change the primary dimension to **Session source** (or Session source / medium).
3. Type `chatgpt` into the table search. Repeat for `perplexity`, `claude`, `gemini`, `copilot`.

## 2. All assistants at once (5 min)

In **Explore**, create a free-form exploration with the dimensions *Session source* and *Landing page*, and add a filter on Session source that **matches regex**:

```text
chatgpt\.com|chat\.openai\.com|perplexity\.ai|claude\.ai|gemini\.google\.com|copilot\.microsoft\.com
```

Now you can see which pages AI assistants send people to. Those pages are your proven answers; build around them.

## 3. A permanent “AI assistants” channel (5 min)

Under **Admin → Data display → Channel groups**, copy the default channel group and add a channel called *AI assistants* with the same regex on Session source. Put it above *Referral* so those visits stop being mixed into it.

## 4. Mind the caveats

- **Direct traffic.** Some AI visits arrive without a referrer and show up as Direct. Microsoft notes the same for its own AI channel.[^clarity]
- **AI Overviews and AI Mode.** Google counts this traffic as normal Google Search traffic.[^g-ai] Read AI impressions in Search Console instead. → [Search Console setup](https://geoasked.com/guides/google-search-console-setup/)
- **Small numbers.** In Microsoft Clarity’s study, AI referrals were under 1% of total traffic, but signed up at a higher rate than search traffic.[^clarity-study] Judge quality, not just volume.

## 5. Connect it to your baseline

Analytics shows the visits AI assistants send. Your prompt baseline shows how often they mention you. Use both: if mentions rise but visits don’t, the answer names you without linking, so work on the page they should cite. → [Track AI visibility](https://geoasked.com/guides/track-ai-visibility/)

## FAQ

### Why does some ChatGPT traffic show as Direct?

When the browser or app doesn’t pass a referrer, analytics can’t tell where the visit came from. Microsoft notes that hidden referrers might appear as Direct. So AI referral numbers are a minimum, not a total.

### Can I see AI Overviews traffic separately in GA4?

No. Google counts traffic from AI Overviews and AI Mode as regular Google Search traffic. Use Search Console’s Generative AI report for AI Overviews and AI Mode impressions.

### Is there a free alternative to GA4 for this?

Microsoft Clarity has a built-in AIPlatform channel that groups visits from ChatGPT, Claude, Gemini, Copilot and Perplexity.
