Google Ads Quality Score: Improve It in 2026

Every week, I talk to business owners and marketing managers who are convinced their Google Ads campaigns are underperforming because of a bad Quality Score. They’ve read the horror stories — a score of 1 can spike your cost-per-click by 400% — and they’re panicking. I get it. But here’s the thing: Quality Score is one of the most misunderstood metrics in all of paid search, and treating it like a report card you need to ace is a mistake I’ve watched cost people real money.

Let me break down what Quality Score actually is, how to move the needle when it genuinely matters, and — this is the part most PPC guides skip — when you should stop worrying about it entirely.

What Is Google Ads Quality Score?

Google Ads Quality Score is a diagnostic rating from 1 to 10 assigned at the keyword level. It estimates how relevant your ad, keyword, and landing page are to the person searching. Google calculates it using three components: expected click-through rate (CTR), ad relevance, and landing page experience.

Think of it like a restaurant health inspection score. It doesn’t tell you whether the food is delicious or whether you’ll make money — it tells you whether you’re meeting baseline standards of cleanliness and safety. Useful? Yes. The whole story? Absolutely not.

Each component gets rated as “below average,” “average,” or “above average.” The combination of those three ratings produces your 1-10 score. Scores of 7-10 are considered good, 5-6 are average, and anything below 5 is a warning sign worth investigating.

Why Quality Score Still Matters in 2026

I’m not going to tell you Quality Score is irrelevant — because the CPC impact is real and it’s getting more pronounced. According to data published by Digital Applied, the CPC gap between top-scoring keywords (8-10) and bottom-scoring keywords (1-3) widened from 3.2x to 3.8x year-over-year heading into 2026, with projections suggesting that gap will keep expanding as Google doubles down on user experience signals in its auction algorithm.

Here’s what that means in plain dollars: a Quality Score of 8-10 delivers roughly 37% lower CPC than the median. Drop to a score of 4 or below, and you’re paying 64% more per click. Hit a score of 1, and your CPC can spike by 400%. That’s not a rounding error — that’s the difference between a profitable campaign and one that bleeds your budget dry.

As of 2026, 36% of keywords score 5 or below — 12% sitting in the 1-3 range and 24% in the 4-5 range. That means over a third of advertiser spend across the platform is carrying some level of CPC penalty. If your account falls into that bucket, fixing your Quality Score is one of the highest-ROI moves you can make.

“High Quality Scores enable 2-3x more clicks on the same budget. It’s the most underutilized lever in paid search, and the gains compound over time.”

The Angle Every Competitor Misses: Quality Score Is a Proxy, Not the Truth

Here’s what almost no one tells you, and it’s the insight that changes how you should think about this entire metric. Quality Score is not the actual metric Google uses in the auction. It’s a diagnostic approximation — a snapshot of how Google perceives your relevance at a moment in time, not the live signal that determines your Ad Rank in real-time bidding.

Google’s actual auction uses a real-time calculation of expected impact that’s far more nuanced than any 1-10 score can capture. The Quality Score you see in your dashboard is updated periodically and averaged across impressions. It’s a lagging indicator, not a live feed.

“Quality Score is a good proxy for auction health, not the exact metric used. Treat it as a directional signal, not gospel.”

— DynaRes.ai, Google Ads Quality Score Analysis, 2026

I’ve seen campaigns with a Quality Score of 6 outperform campaigns with a score of 9 — because the lower-scored campaign had tighter audience targeting, better bid strategy alignment, and landing pages that converted at a higher rate. The score looked mediocre. The results were excellent. That’s why I tell my clients: chase performance, not the number.

This matters even more now that broad match keywords inherit Quality Scores from their exact match counterparts when impressions exist, and AI-driven evaluation of landing pages has made the scoring process noisier. Tools like Optmyzr have noted that scores can feel “blunt” in an era of AI-expanded match types — but a low score still reliably signals an intent mismatch worth fixing.

How to Actually Improve Your Quality Score

When I audit a new client’s Google Ads account, the first thing I do is add Quality Score columns to the Keywords tab. Go to Keywords → Columns → Modify Columns → Add Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. That four-column view tells you exactly which component is dragging your score down — and that’s where you start.

Fix Expected CTR First

Expected CTR is Google’s prediction of how likely someone is to click your ad when it appears for a given keyword. It’s benchmarked against other ads competing for the same keyword, so you’re not just competing against yourself — you’re competing against everyone in the auction.

The fastest way to move this needle is to write headlines that directly match search intent. If someone searches “emergency HVAC repair Orlando,” your headline should say “Emergency HVAC Repair in Orlando” — not “Trusted Home Services Since 1998.” Specificity wins. Use Responsive Search Ads with multiple headline variations that include the exact keyword or close variants, and let Google’s machine learning surface the combinations that earn the most clicks.

Tighten Ad Relevance

Ad relevance measures how closely your ad copy matches the intent behind the keyword. This is where I see the most waste in accounts I inherit — broad ad groups where one set of ads is trying to serve 40 different keywords, none of which are well-represented in the copy.

The fix is tighter ad group structure. Group keywords by intent, not just theme. “Buy running shoes” and “best running shoes for flat feet” are the same theme but completely different intents — one is transactional, one is informational. They deserve different ads. Include the primary keyword naturally in at least one headline and in the description. It sounds obvious, but I still see accounts where the keyword doesn’t appear anywhere in the ad text.

Optimize Your Landing Page Experience

This is the component that has the biggest real-world impact on your business — and the one most advertisers treat as an afterthought. Google evaluates landing pages for relevance, load speed, mobile-friendliness, and whether the page delivers what the ad promised. A fast, relevant landing page doesn’t just improve your Quality Score; it improves your conversion rate, which is the metric that actually pays your bills.

For landing page speed specifically, I’d point you to our breakdown of PageSpeed vs Core Web Vitals — the same signals that affect your organic rankings are influencing how Google evaluates your paid landing pages. Fix your Core Web Vitals and you’re improving both channels simultaneously.

Ensure the landing page headline mirrors the ad’s primary promise
Load time should be under 3 seconds on mobile — use Google’s PageSpeed Insights to verify
The page should be clearly relevant to the keyword — not just your homepage
Remove friction: one clear call to action, no confusing navigation pulling users away
Make sure the page is genuinely useful — Google’s AI is evaluating content quality, not just keywords

The Quick Formula Worth Knowing

There’s a simplified way to think about how your score is built: Quality Score ≈ 1 + (landing page score + expected CTR score + ad relevance score). Each component is rated on a 1-3 scale internally. That means the maximum possible score is 10 (1 + 3 + 3 + 3), and a score of 4 typically means one component is dragging everything down. Identify the weakest link and fix that first — don’t spread your optimization effort equally across all three.

When to Stop Caring About Quality Score

I promised you honesty, so here it is: there are real scenarios where chasing a higher Quality Score is a distraction from what actually matters.

First, Quality Score only applies to search campaigns. If you’re running Performance Max, Display, YouTube, or Shopping campaigns, Quality Score is irrelevant — those campaign types use entirely different signals. With the rapid growth of Performance Max (and Google’s push to migrate advertisers toward it), a significant portion of your spend may already be in a world where Quality Score doesn’t apply. Our post on Google Ads AI Max replacing Dynamic Search Ads covers how this shift is changing the paid search landscape.

Second, a low Quality Score on a keyword that’s converting profitably is not necessarily a problem to fix. I’ve managed accounts where a keyword with a score of 4 was generating a cost-per-acquisition 30% below target. Should I pause it or restructure the ad group to chase a higher score? No — I should leave it alone and focus on scaling what’s working.

The real goal is profitable conversions, not a perfect score. Quality Score is a tool for diagnosing inefficiency, not a trophy to display. Use it to find waste. Don’t let it become the waste.

This connects to a broader point about how we measure success in digital marketing — something I explored in our piece on the metrics that actually matter. The principle applies equally to paid search: optimize for outcomes, not optics.

Frequently Asked Questions

What is a good Google Ads Quality Score?

Scores of 7-10 are considered good and will reduce your cost-per-click relative to the auction median. Scores of 5-6 are average and carry no significant penalty or benefit. Scores below 5 — especially 1-3 — indicate a relevance problem and will increase your CPC substantially, sometimes by 64% or more.

How often does Google update Quality Score?

Quality Score is updated continuously as Google gathers more data on your ads, keywords, and landing pages. However, the score you see in your dashboard is a rolling average — it won’t change overnight based on a single optimization. Give changes 2-4 weeks to reflect in your reported score.

Does Quality Score affect Performance Max campaigns?

No. Quality Score is specific to search campaigns. Performance Max, Display, Shopping, and YouTube campaigns use different quality and relevance signals that are not surfaced as a 1-10 Quality Score in your dashboard.

Can I have a high Quality Score and still lose the auction?

Absolutely. Ad Rank — the actual auction outcome — is determined by your bid multiplied by your quality signals, plus the expected impact of ad extensions and other factors. A competitor with a lower Quality Score but a significantly higher bid can still outrank you. Quality Score improves your efficiency; it doesn’t guarantee you win every auction.
