How to Track ChatGPT, Perplexity and Gemini Traffic in Google Analytics 4

When someone asks ChatGPT "best web designer in Ludhiana" or Perplexity "how much does a taxi from Amritsar to Delhi airport cost", the answer often includes links. When people click those links, they arrive on websites as real visitors. The volume is still small for most businesses, but it's growing — and these visitors often arrive with high intent because the AI has already recommended you.

Google Analytics 4 (GA4) can show this traffic, but by default it's mixed in with other referrals. Here's how to find it and track it properly.

Where AI traffic shows up

Most AI assistants send visitors as referral traffic, with the assistant's domain as the source. Common sources include:

Domains can change, and some app-based clicks arrive without any referrer, which GA4 records as "direct". So what you see is a minimum, not the full picture.

Quick check: see AI referrals in 2 minutes

1. In GA4, go to Reports → Acquisition → Traffic acquisition.
2. Change the primary dimension to Session source / medium.
3. Use the search box and type chatgpt, then perplexity, gemini, copilot.
4. Set the date range to the last 3–6 months to see the trend.

Better: create an "AI Assistants" channel

A custom channel group puts all AI traffic in one row so you can compare it with Organic Search, Paid Search and Social.

1. Go to Admin → Data display → Channel groups.
2. Copy the default channel group and give it a name such as "Channels with AI".
3. Add a new channel called AI Assistants.
4. Set the condition: Source matches regex:

   .*(chatgpt|openai|perplexity|gemini\.google|copilot|claude\.ai|you\.com).*

5. Move this channel above "Referral" in the list, because GA4 assigns the first matching rule.
6. Save. The new grouping applies to reports and, in most cases, to historical data as well.

Then in the Traffic acquisition report, switch the dimension to your new channel group.

Measure what matters: leads, not just visits

Visits alone don't tell you much. Make sure you track conversions — phone clicks, WhatsApp clicks and form submissions — as key events in GA4. Our guide to Google Tag Manager shows how to track button clicks without editing code, and our conversion tracking guide explains the events to set up.

Then compare AI Assistants with other channels on:

• Engagement rate
• Key events per session
• Landing pages they arrive on

Landing pages are especially useful: they show which content AI assistants are recommending. Strengthen those pages and create more like them.

What GA4 can't show you

• Google AI Overviews and AI Mode: clicks from these appear as normal Google organic traffic. Search Console includes them in overall performance data but doesn't separate them clearly.
• Mentions without clicks: if ChatGPT recommends your business and the user calls you directly, GA4 never sees it. Ask new customers "How did you find us?" — and add "ChatGPT / AI assistant" as an option in your enquiry form.
• Apps that strip referrers: some clicks from mobile apps show as direct traffic.

Check how AI describes you

Alongside analytics, do a monthly manual check: ask ChatGPT, Gemini, Perplexity and Copilot questions your customers would ask, and note whether your business appears and how it's described. Keep a simple log. If details are wrong, update your website, Google Business Profile and directory listings so the correct information is consistent everywhere. Our GEO guide covers how to improve these results.

Frequently Asked Questions

Why is my AI traffic so small?

For most local businesses, AI referrals are still a small share of total traffic. The trend and conversion rate matter more than the absolute number right now.

Does ChatGPT traffic count as organic search?

No. By default GA4 treats it as referral traffic unless you create a custom channel for it.

Can I see which questions people asked the AI?

No. AI assistants don't pass the user's prompt to your website.

Will this work with Universal Analytics?

Universal Analytics stopped processing data in 2023. Use GA4.
