Can Fort Wayne Businesses Finally Track Their Google AI Traffic?

For two years, the honest answer to “is the AI stuff actually sending me any customers?” has been a shrug. A Fort Wayne HVAC company or dental office could be getting mentioned by Google’s Gemini, and the visits would land in Google Analytics as a vague lump of “direct” traffic — the same bucket as someone typing your web address from memory. You were told to optimize for AI, but you had no clean way to prove it was working before you spent money chasing it.

That just changed a little. Google has started attaching UTM parameters to the links Gemini sends out, which means that traffic can finally be identified as its own source in your reports. It’s a real step, and it’s also narrower than the headlines suggest. This guide walks through what changed, exactly where Gemini traffic now surfaces in Google Analytics 4 (GA4), how a non-technical owner can set up a report to watch it weekly, and — just as important — the things this data still can’t tell you. If you’re newer to all of this, The Fort Wayne Small Business Guide to AI covers the fundamentals first; this post is the measurement piece that sits on top of them.

• Google is now adding UTM tags to outgoing Gemini links, so Gemini visits can register as an identifiable source in GA4 instead of disappearing into “direct.”
• GA4 already added an automatic AI Assistant channel in 2026 that labels recognized AI referrals with the medium `ai-assistant` — no setup required.
• You’ll find this traffic under Reports → Acquisition → Traffic acquisition, using the Session source / medium dimension.
• The tagging is undocumented and forward-only: it won’t backfill old visits, and a large share of AI referrals still land in “direct.”
• For most Fort Wayne small businesses, AI referral traffic is still a trickle today — this lets you measure the trend honestly rather than guess at it.
• If you want the number to mean something, tie it to booked jobs, not just sessions.

What Actually Changed With Google Gemini Traffic?

Here’s the mechanics, in plain English. When Gemini answers a question and links out to a website, that click used to arrive with little or no identifying information. The referrer — the behind-the-scenes note that says “this visitor came from here” — often got stripped on the way, especially on phones. As Search Engine Journal reported, the referrer “mostly survives on desktop web only,” and pass-through from the Gemini mobile app reportedly “runs around 9 percent,” with Android assistant invocations stripping it entirely.¹ The practical result: a Gemini visit on a phone usually showed up in your analytics as “direct,” indistinguishable from someone who already knew your name.

A UTM parameter fixes that in a sturdier way. It’s a small tag added to the end of a link (the `utm_` bits you’ve probably seen in long URLs) that rides along inside the in-app browser and survives where the referrer doesn’t. Google is now adding these tags to Gemini’s outbound links, mirroring what ChatGPT already does. For the first time, a chunk of Gemini traffic can be counted as Gemini traffic.

Two honest caveats come straight from the reporting. First, the exact tag values Google is using are undocumented — Google hasn’t published which `utm_source` or `utm_medium` labels Gemini applies, so the smart move is to look in your own account rather than trust a value you read in a blog post. Second, nobody outside Google yet knows exactly when the tag fires — presumably when Gemini references a website directly, but that isn’t confirmed. This is new plumbing, not a finished dashboard. If you’ve been reading our coverage of what AI Overviews are doing to website traffic, think of this as the measurement side finally catching up to the disruption side.

Where Does Gemini AI Traffic Show Up in Google Analytics?

Good news: you don’t necessarily need the new UTM tags to start seeing AI traffic, because GA4 did some of the work already. In 2026 — reaching broad availability that June — Google added a native AI Assistant default channel to GA4. According to AuthorityTech’s analysis, recognized AI sources get labeled automatically with a Session medium of `ai-assistant` and a Session campaign of `(ai-assistant)` — no configuration on your end.³ Google’s help page names ChatGPT, Gemini, DeepSeek, Copilot, and Grok as *examples* — but as AuthorityTech stresses, that’s an illustrative list, not a complete roster, and Google’s own release notes confirm Claude and Perplexity are recognized too.

To find it, open GA4 and go to Reports → Acquisition → Traffic acquisition. Change the primary dimension to Session source / medium. Per Google’s own Analytics documentation, that’s where source, medium, and campaign values from both UTM tags and GA4’s channel rules surface.² If you see a row where the medium reads `ai-assistant`, Google is recognizing that referrer for you. If Gemini visits instead show up under a source like `gemini.google.com` with the new UTM tags, you’ll see those too — the point is they’re no longer buried in “direct.”

Here’s a quick map of what you can expect to see and what each view actually tells you:

This is a different measurement than whether you *appear* in AI answers at all. If your question is “does Google’s AI even mention my business,” that’s a visibility question, and we covered the free tool for it in our guide to tracking AI search visibility in Search Console. What we’re talking about here is the step after that: once AI mentions you, did anyone actually click through — and can you see it?

How Do You Build a Report to Watch Your AI Traffic?

If the automatic AI Assistant channel is live in your property, a lot of this is handled. But because Google won’t publish its recognized-referrer list, it’s worth building your own custom channel group so you catch sources GA4 misses. AuthorityTech lays out a clean, no-developer version of this:

1. In GA4, go to Admin → Data display → Channel groups.
2. Create a new channel group and add a channel — call it something like “AI Search.”
3. Set a rule where Source matches a regular expression listing the AI domains you care about (for example, patterns covering `gemini.google.com`, `chatgpt.com`, `perplexity.ai`, and `claude.ai`).
4. Position that channel above Referral, since GA4 evaluates rules top-down.
5. Save, then verify in your Traffic acquisition report over the next few days.

That gives you one line to watch each week instead of hunting through rows. For the owner who just wants a number, the one-minute version is simpler still: open Traffic acquisition, set the dimension to Session source / medium, and scan for `ai-assistant` or any AI domain. Seer Interactive makes the same core point in its practical guide to tracking AI traffic — when UTMs and referrers are missing, AI visits inflate your “direct” bucket and quietly skew your channel numbers, so isolating them is the only way to read your reports honestly.⁴

If you’re already running basic point-and-click event tracking, this slots in naturally alongside it. The goal isn’t a prettier chart. It’s being able to say, with a straight face, how many booked jobs started with an AI answer.

What Can This Data NOT Tell You?

This is the part most “track your AI traffic” articles skip, and it’s the part that keeps you from making a bad decision. Three honest limits:

A big share of AI traffic still lands in “direct.” AuthorityTech estimates that somewhere between 35% and 70% of AI referral sessions arrive with no referrer header at all, and no rule can recover those.³ UTM tagging shrinks that gap for Gemini, but it doesn’t close it. Your reported AI number is a floor, not the full picture.

It’s forward-only. Both AuthorityTech and Seer note that GA4’s AI Assistant channel doesn’t reclassify historical sessions. The day it turned on is the day your clean data starts. So don’t compare “AI traffic last month” to this month and read a trend into it that’s really just the tagging switching on.

It counts clicks, not customers. Sessions are easy to measure and easy to over-value. For a local service business, the honest metric is still booked jobs and real phone calls. A spike of Gemini sessions that books nothing is a vanity number. We made this case in detail in turning AI-search visibility into tracked leads, and it applies here too: measure the whole path, not just the doorway.

One more bit of context worth keeping in your head. AuthorityTech’s data shows Gemini’s share of AI-assistant referral traffic climbing from 2.31% to 9.0% year-over-year — real growth, and enough to make it the second-largest AI referral source behind ChatGPT.³ But “second-largest slice of a still-small pie” is the honest framing for most local businesses. AI referral traffic is growing; for a Fort Wayne shop today it is usually still a trickle, not a flood.

What This Means for a Fort Wayne Business

If you run an HVAC company in Allen County, a dental practice in Fort Wayne, or a restaurant in New Haven, here’s the practical takeaway. You’ve likely been pitched “AI optimization” by someone, and you had no way to check their work. Now you have a free one: open GA4, look at Traffic acquisition, and see whether Gemini and other assistants are sending anyone at all. If the number is near zero, that’s useful information — it means AI referral traffic isn’t your priority yet, and you can put that budget toward the fundamentals that still drive calls. If it’s growing month over month, that’s your signal to invest more deliberately, and it pairs naturally with connecting your Google Business Profile to Gemini so the AI has accurate information to pass along.

Either way, you’re deciding with data instead of a sales pitch. That’s the whole point, and it fits how we think a Northeast Indiana business should approach AI in general — start small, measure honestly, and only scale what pays.
