Google Ads Call Quality Scoring: What Gemini Changes

Table of contents

Summary

Google Ads call quality scoring has been upgraded at GML 2026. Gemini now analyses call content to distinguish genuine enquiries from misdials, wrong numbers, and short non-conversions. The result is that Smart Bidding gets cleaner signal data about which calls actually led to a business outcome. The feature is currently in pilot in Canada and the US. UK advertisers cannot access it yet, but there is a practical workaround using offline conversion imports that achieves a similar outcome today.

The problem with duration-based call scoring

For as long as Google Ads has tracked phone calls, the quality signal has been time.

A call lasted more than 60 seconds? Counted as a conversion. Short call? Probably a bounce, not counted. That was the logic.

It is a blunt instrument, and it has always been a blunt instrument.

Here is what happens in practice. A prospect calls a plumber, gets put on hold for 90 seconds, hangs up in frustration, and never books. Google counted that as a conversion. Smart Bidding treated it as a positive signal. The algorithm bid harder on the keyword that drove it.

Meanwhile, a commercial buyer who already knows exactly what they want calls, confirms availability, and books in 45 seconds flat. Too short. Not counted. Google learned nothing useful from it.

I have sat in account reviews where the conversion data looked strong and the actual business results told a completely different story. Calls up, revenue flat. You dig in and find the call duration threshold is doing the reporting, not the reality.

That is the problem Gemini is now being used to fix.

What Gemini actually does differently

At Google Marketing Live 2026, Google announced that Gemini is now being applied to call quality scoring inside Google Ads.

Rather than using duration alone, the system analyses the content of the call. It can identify:

• Misdials and wrong numbers. Someone calls the wrong business and hangs up. Under the old system, if they stayed on long enough to hear the voicemail greeting, that might have counted. Under Gemini scoring, it does not.
• Call intent. The content and context of the conversation gives a signal about whether this was a genuine enquiry or not.
• Campaign attribution. Calls are traced back to the specific campaign, ad group, or keyword that drove them. This means the quality signal does not just say “a call happened.” It says “this campaign drove a call that looked like a qualified lead.”

The outcome is that Smart Bidding receives a better quality signal. Not just “a call occurred,” but something closer to “a call occurred that resembled the kind of call that leads to business.”

This sits alongside two other lead quality announcements from GML 2026: Lead Intent Scores and Lead Journey Mapping. Together, they are Google’s push to close the gap between a platform conversion and an actual sale. Call quality scoring via Gemini is the phone-specific part of that cluster.

Where this sits in Smart Bidding

Smart Bidding is only as good as the signals you feed it.

If your conversion tracking records every 60-second call as equal, the algorithm has no way of knowing which of those calls was a genuine lead and which was a confused pensioner who dialled the wrong number. It bids accordingly, which is to say, it bids badly.

Better call quality data does two things.

First, it stops the algorithm rewarding poor-quality traffic. If a keyword consistently drives misdials and short confused calls, Gemini scoring surfaces that. Smart Bidding can stop over-investing in it.

Second, it reinforces the campaigns and keywords that drive calls that look like real enquiries. Over time, the algorithm learns what good traffic looks like for your account and bids harder for more of it.

This is the same principle that makes offline conversion imports valuable. When you import CRM data back into Google Ads, saying “this form fill became a paying customer,” Smart Bidding learns to find more people who look like that paying customer. Call quality scoring via Gemini is an automated version of that logic, applied to phone calls in real time.

The caveat is the same one that applies everywhere in automated bidding. The signals have to be accurate. If your call tracking is misconfigured, if calls are being double-counted, or if you are attributing calls to the wrong campaign, Gemini scoring feeds better analysis into a broken foundation. Audit your call tracking setup before trusting any of this.

What UK advertisers should do right now

The honest answer: you cannot access Gemini call quality scoring yet.

The feature is in pilot in Canada and the US. Google has not announced a UK rollout date. That is frustrating if you run call-heavy campaigns, which many UK service businesses do.

But there is a practical workaround that achieves a meaningful version of the same outcome.

Offline conversion imports. If your sales team logs calls in a CRM, you can export the ones that became actual customers and import them back into Google Ads as a separate conversion action. You are not relying on Google to infer call quality. You are telling it directly: this call was good, this one was not. Smart Bidding uses that data.

This takes some setup. You need your CRM to track the source of each enquiry, and you need a process for exporting and importing that data regularly. But the signal quality it produces is arguably better than what Gemini call scoring will give you, because it is based on actual sales outcomes, not call content analysis.

While you wait for the UK pilot, get that import set up. When Gemini call scoring does roll out here, you will have clean historical data to run alongside it.

What to watch for. Google typically expands pilots to the UK within 3 to 9 months of a North American rollout. Keep an eye on your Google Ads interface for a call quality option appearing in your conversion settings. When it does, review your existing call conversion actions and decide whether to replace duration-based scoring or run both in parallel during a transition period.

For a full view of how your current Google Ads setup is handling call attribution and conversion tracking, an independent Google Ads audit is the cleanest starting point.

FAQs

What is Google Ads call quality scoring?
Call quality scoring is how Google Ads decides whether a phone call from an ad represents a genuine lead. Historically this was based on call duration. At GML 2026, Google announced that Gemini now analyses call content to identify misdials, wrong numbers, and intent signals, giving Smart Bidding a more accurate signal to work with.

How does Gemini improve call lead scoring in Google Ads?
Gemini analyses the content and context of calls rather than just how long they lasted. It can identify whether a call was a misdial, a genuine enquiry, or a poor-fit contact, and traces each call back to the campaign that drove it. That information feeds into Smart Bidding, helping it invest more in the traffic that drives real conversations.

Is call quality scoring available in the UK?
Not yet. As of May 2026, Gemini call quality scoring is in pilot in Canada and the US only. UK advertisers who want better call signal data can use offline conversion imports in the meantime, importing CRM records of calls that became customers directly into Google Ads.

Does this replace call duration tracking?
It is designed to improve on it, not necessarily replace it outright. Duration can still be a useful proxy signal. The Gemini layer adds content analysis on top of duration, so the two are likely to work alongside each other during any rollout period. When the feature reaches your account, review whether your existing duration thresholds still make sense.

Will call quality scoring improve my Smart Bidding results?
Cleaner signal data generally helps Smart Bidding perform better over time, particularly in accounts where call quality varies a lot. But the improvement depends on how accurate your underlying call tracking already is. If calls are being miscounted or misattributed, fix that first. Better analysis on bad data does not produce better results.
