Quality Score in 2026: Is It Still a Relevant KPI?

Ten years ago, showing a Quality Score below 7 on a strategic keyword felt like a professional failure. Teams rebuilt entire accounts to claw back two or three points, and the 10 out of 10 was chased like an Olympic medal. In 2026 the scenery has changed completely, if you still spend your optimization meetings pushing that number up, I’m sorry to tell you that you are treating the wrong indicator.

How Quality Score actually works, in two minutes

Quality Score is a rating from 1 to 10 that Google assigns to each keyword in your Search campaigns. It rests on three pillars:

• The first is expected click through rate, meaning how likely someone is to click your ad when it shows for a given query.
• The second is ad relevance, or how closely your message matches the intent behind the keyword.
• The third, often the most telling, is the landing page experience: the speed, the clarity and the real usefulness of the page where the visitor arrives.

On paper, a high Quality Score improves your Ad Rank, which lets you reach a better position for a lower cost per click. In practice this mechanism has been widely outpaced by how the platform has evolved, and that is exactly where things get interesting.

Why Quality Score no longer rules performance

Smart Bidding reshuffled the deck

The moment you steer your bids with tCPA or tROAS, Google makes its decisions from hundreds of contextual signals analyzed in real time: device, time of day, location, search history, estimated intent. In concrete terms, a keyword rated 4 that posts an excellent real conversion rate can easily outperform a keyword rated 9 that never converts.

Performance Max does not even have a Quality Score

Here is the point many teams forget, Performance Max, which captures a growing share of Google Ads budgets in 2026, has no Quality Score at all. The metric simply does not exist on this campaign type. It is hard to build a strategy around a number that is absent from your most budget hungry campaigns.

Responsive ads make manual optimization pointless

With Responsive Search Ads, Google assembles headlines and descriptions on the fly for every query. Trying to optimize each possible combination to lift the score of one precise keyword is like chasing the wind. The algorithm tests, arbitrates and recomposes continuously, far faster than any account manager, however meticulous.

What Quality Score still reveals

Dropping it as a goal does not mean throwing it away, in 2026 the score remains a genuinely useful diagnostic tool.

A persistently low Quality Score is never an accident, it’s the visible symptom of a deeper problem. It can come from ads that drift too far from the keywords they target, from a landing page that answers search intent poorly, or from an account structure too generic to be relevant. Among the three components, the landing page experience is often the most revealing. A “below average” status in that exact spot sends a clear signal: your page is slow, off topic or poorly built to convert. That problem deserves a fix because it is costing you very real conversions.

On an account audit, especially for a new client, the average rating offers a fast snapshot of overall health, it’s a handy entry point.

The metrics that drive your campaigns in 2026

So where do experienced teams keep their eyes fixed? First on real CPA and ROAS compared against targets, because that is the final result, with no proxy in between. Next on impression share and lost impression share, which show precisely where you are letting visibility slip away, whether through budget or ranking. Conversion rate segmented by device, audience or geography then helps identify what actually pays back every euro invested. On the creative side, the asset performance score reports on the quality of your RSA elements and guides your testing. Finally, Auction Insights let you watch competitive pressure and anticipate market moves.

You will notice that Quality Score is not on this list, there is a simple reason for that: the score is not a key performance indicator and should not be optimized for its own sake.

Our verdict: not a target anymore

Quality Score is a bit like the SEA version of a school report card. Useful for spotting students in trouble, quite limited for predicting professional success. In 2026, if a provider assures you the account is healthy because it shows an average Quality Score of 8.5, ask the only question that counts: and what is the ROAS?

Put your energy and your budget where they create concrete results: the reliability of your tracking, the relevance of your landing pages and the strength of your Smart Bidding logic. That is exactly the work our Google Ads team at Donutz Digital does every day, on multi country and multilingual accounts.

FAQ

Does Quality Score still affect cost per click in 2026?

Yes, but indirectly. A high score can still lower your cost per click through Ad Rank on classic Search campaigns. With Smart Bidding and Performance Max, though, that effect dilutes into hundreds of other signals. Your final cost per click depends far more on the quality of your conversion data than on the number shown against your keywords.

Should you ignore Quality Score in Google Ads completely?

No. Stop treating it as a goal and start reading it as a diagnostic tool. A persistently low score flags a real problem with your ad, your landing page or your account structure. Fix the cause, not the symptom, and the score follows on its own.

Why does Performance Max have no Quality Score?

Because Performance Max does not work at the keyword level. The campaign relies on full Google automation, which blends your audience signals, your product feed and your creative assets. Quality Score, designed for keyword based Search, has no place in that logic.

Which metric should you track instead of Quality Score?

Look first at your real CPA and ROAS against your targets, then at your segmented conversion rate and your lost impression share. These are the metrics that tell the true story of your profitability, far better than a rating from 1 to 10.

How can you improve the landing page experience?

Work on load speed, on the match between the ad message and the page content, and on the clarity of the path to conversion. A fast, consistent and action focused page improves both your Quality Score and, above all, your real conversion rate.
