About this data
This index aggregates anonymized referral traffic from a panel of 1,429 GA4 properties connected to Trakkr by their owners. Sessions are filtered where the source contains "gemini.google.com" and normalized to the highest traffic day (= 100%). Industry categories come from GA4. Updated daily at 00:00 UTC.
Gemini sessions are identified where the GA4 source matches gemini.google.com and related Google AI surfaces, then aggregated across the panel of 1,429 properties. AI Overviews in classic Search are tracked separately and are not counted here.
The data is first-party and aggregated — site owners connect their own Google Analytics, and no individual visitor is ever identified.
What is Gemini referral traffic?
Gemini referral traffic is the visits your website receives when someone clicks a link inside a Google Gemini answer. Because Gemini is woven through Google Search (AI Mode), Workspace, Chrome, and Android, its referrals come from a uniquely broad surface area compared with standalone chat assistants.
In Google Analytics 4, these sessions appear with a source containing "gemini.google.com" (and related Google AI surfaces). Gemini's tight coupling with the wider Google ecosystem means its referral volume often moves with Google product launches and Search rollouts rather than on a standalone release cadence.
The Trakkr Gemini Traffic Index tracks this referral traffic daily across 1,429 GA4 properties so you can see whether a shift in your own Gemini traffic reflects a market-wide move or something specific to your site.
How much traffic does Google Gemini send to websites?
Gemini referral traffic varies widely by industry and site authority. Across the Trakkr panel of 1,429 GA4 properties that receive Gemini traffic, Gemini is a meaningful and growing referral source, though still smaller than ChatGPT for most sites. Its reach benefits from deep integration across Google Search, Workspace, and Android.
Is Gemini referral traffic growing?
Gemini traffic fluctuates week to week but has trended upward as Google has expanded AI answers across Search (AI Mode), Chrome, and Android. The Trakkr Gemini Traffic Index tracks the real trajectory daily across 1,429 websites so you can see past the short-term noise.
How do you measure Gemini referral traffic?
Gemini traffic is measured through Google Analytics 4 by filtering sessions where the source contains "gemini.google.com" and related Google AI surfaces. Trakkr aggregates this first-party data from anonymized GA4 properties and normalizes it to the highest-traffic day (= 100%) to show relative trends without exposing absolute numbers.
Is Gemini traffic the same as Google AI Overviews?
No. Gemini referral traffic comes from the Gemini app and gemini.google.com surfaces. AI Overviews are the AI answers that appear inside classic Google Search results, which carry Google's standard search referrer. This index tracks Gemini specifically and reports it separately from AI Overviews.
Which industries get the most traffic from Gemini?
Industry performance shifts over time. The Gemini Traffic Index breaks referral traffic down across verticals such as Commerce, Technology & Finance, and Lifestyle & Health so you can see which sectors are gaining or losing Gemini traffic in real time.
How can I track Gemini traffic to my own website?
Connect your Google Analytics property to Trakkr to see exactly how much traffic Gemini, ChatGPT, Claude, Perplexity, and other AI platforms send to your site. Trakkr automatically filters and categorizes AI referral traffic and benchmarks you against industry averages.
