How to Track AI Search Traffic

Everyone is talking about ChatGPT, engaging with AI Overviews, and AI Mode – but how do you know if any of this traffic is actually getting to your website? While it seems like there’s a hot new tool every day to measure AI visibility, they can be expensive. So, we’re going to show you how to track AI search traffic using the tools you probably already have: Google Analytics, Bing Webmaster Tools, and some well-informed best estimates.

AI Search Traffic Is Worth Tracking (Even If the Numbers Are Small)

Everyone may be talking about AI, but as of February 2026, Google sends 190x more traffic to websites than ChatGPT, the most popular LLM as of that date. When ChatGPT sends 0.21% of traffic to websites, is it even worth it?

Yes, it is. This traffic may be small now, but it’s expected to increase exponentially. Knowing how you’re performing now can help you identify areas of strength and opportunity and may put you ahead of the competition.

Tracking and optimizing for AI search traffic also sets you up for success in Google AI Overviews and AI Mode, both of which are considered Organic traffic by Google and included in Search Console metrics. Key optimizations for ranking in AI search engines are also applicable to these AI features. And with Google owning nearly 90% of search engine market share, having a site that ranks where your customers are is critical.

Use What You Have: AI Referral Traffic in GA4

The first step to tracking AI traffic is isolating it in GA4. The most easily identified traffic can be found in your Acquisition reports. Go to Acquisition > Traffic acquisition, for example, and set your primary dimension as Session source / medium. Type “referral” in the table search and look for gemini.google.com / referral, chatgpt.com / referral, etc. This method is unlikely to capture all AI traffic, but it should give you a good estimate.

Instead of digging into referral traffic each time, you can set up a Custom Channel Group to cover the major AI sources:

Go to GA4 → Admin (gear icon, bottom left) → Under “Data display,” click Channel groups → Create new channel group
Name your group “AI Traffic Group” or a similar name that is easy to find
Click Add new channel and give it a name (“AI” or “Artificial Intelligence”)
Condition type: Source
Match type: Matches regex
Paste this regex (add more over time):
chatgpt\.com|openai\.com|perplexity\.ai|claude\.ai|gemini\.google\.com|copilot\.microsoft\.com|copilot\.com|you\.com|phind\.com|bing\.com
Save your channel
You’ll be taken to the Channel list; click Reorder and move your new channel up the list so it’s before Referral to make sure traffic is assigned to AI
Save Group

Note that this new channel will not backfill but will track data moving forward. Once data starts being collected, go to Reports → Acquisition → Traffic acquisition. Click the dimension dropdown in the table and switch from “Session default channel group” to “Session custom channel group” and you’ll be able to see your AI Traffic Group.

If you don’t have space for a new Custom Channel Group, you can create a similar report in Data Studio. Using the regex above, create a filter called “AI Traffic”:

Include → Session source / medium → RegExp Match → paste your regex

You can use this filter on GA4 data by Session source.

The AI Overviews Problem … and a Workaround

AI Overviews (AIOs) are harder, because clicks from them arrive as regular Google organic traffic. There’s no referring domain to catch. The only signal Google leaves behind is the Text Fragment parameter in the URL.

Many keyword tracking tools now also report on AI Overview presence, but with search personalization increasing, what appears in your results may not appear for someone else – making those tools useful for trend data, but not a reliable count of your specific traffic.

There are methods to estimate AI Overview traffic in GA4, with some important caveats:

This method also includes traffic from Featured Snippets (5.5% visibility in June 2025) and People Also Ask, which cannot easily be distinguished.
Only clicks from Chromium-based browsers will be counted.
If your site (or your visitors’ browsers) block Text Fragments, those clicks will not be tracked as coming from AIOs.

These concerns mean that the data you can track will likely appear lower than it actually is; it’s a floor rather than a ceiling. Setting up an Event in GA4 that fires when the Text Fragment #:~:text= parameter is present in a page URL will reveal real traffic coming from AIOs, Featured Snippets, and People Also Ask, all of which are worth optimizing for.

The Text Fragment tracking technique first documented by Dana DiTomaso, and gives you a directional estimate of clicks from AI Overviews and the sources above. Her article provides a step-by-step guide to the GTM implementation.

Bing Webmaster Tools: Your Secret Weapon

Bing may drive less overall search traffic than Google, but it’s a lot more transparent about AI performance. In February 2026, Microsoft announced AI Performance reporting in Bing Webmaster Tools. This dashboard provides a consolidated – and sometimes sampled – view of data collected from “Microsoft Copilots and Partners”:

Total Citations
Average Cited Pages
Grounding queries (key phrases the AI used when retrieving content)
Page-level citation activity
Visibility trends over time

Webmaster Tools is free to use. Sign up at https://www.bing.com/toolbox/webmaster/ if you don’t already have an account.

Putting Data into Action

Tracking AI search traffic is not about achieving perfect measurement. It’s about building enough visibility to spot trends, prove value, and make smarter content decisions before your competitors do.

Start with what you have: a GA4 custom channel group, a Text Fragment event, and Bing Webmaster Tools’ AI Performance report. Together, these give you a meaningful picture of how AI-driven discovery is already affecting your site. As the tools and platforms mature, your tracking can grow with them.
