Google Ads Quality Score: What It Actually Measures (And What to Ignore)
Google Ads Quality Score is a 1 to 10 rating Google gives each of your keywords to estimate how relevant your ad, keyword and landing page are to the person searching. A higher score tells Google your ad is a good match, which can lower what you pay per click and help your ad show more often. A low score does the opposite: you pay more for worse positions. It is Google’s shorthand for “how useful is this ad likely to be.”
Here is the part most guides skip: Google Ads Quality Score is a diagnostic, not a target. It is a simplified read-out of three things Google already judges, and chasing the number itself is mostly wasted effort. What matters is fixing the real drivers behind it. This guide explains what Google Ads Quality Score actually measures, what it affects, what you can safely ignore, and the handful of moves that genuinely improve it.

What Is Google Ads Quality Score?
Google Ads Quality Score is a keyword-level rating from 1 to 10 that Google shows in the keyword table of your account. It is an estimate of the quality of your ads and landing pages for that keyword, built from historical performance data. You can add it as a column in Google Ads, along with its three component ratings, to see it per keyword.
The important nuance is that the 1 to 10 number is a reporting diagnostic. It is not the exact figure plugged into each live auction. In the real-time auction, Google uses fresh quality signals to work out your Ad Rank, and the reported Quality Score is a simplified summary of those same signals over time. So treat it as a health gauge that tells you where to look, not a live dial you can turn. If a keyword shows a low score, it is Google telling you one of three things needs work.
What Does Quality Score Actually Measure?
Quality Score is built from three components, each rated Below average, Average or Above average. Those labels are where the real information is, because they tell you exactly which lever to pull.
| Component | What it judges |
|---|---|
| Expected click-through rate | How likely people are to click your ad when it shows for that keyword |
| Ad relevance | How closely your ad copy matches the intent behind the keyword |
| Landing page experience | How relevant, useful and fast your landing page is for someone who clicks |
Read the components, not just the number. A keyword scoring 5 with “Below average” landing page experience is telling you to fix the page, not the bid. One with “Below average” ad relevance means your ad does not speak to the search. This is why the diagnostic is useful: it points at the specific weak spot. The three drivers also feed straight into what you pay, which is covered below, and they are exactly what a good account audit checks first.
What Quality Score Does Not Do (And What to Ignore)
Quality Score does not reward tricks, and it is not a scoreboard to win. The single most common mistake is treating the 1 to 10 number as a KPI and obsessing over nudging a 7 to an 8. That effort rarely pays. Ignore the number in isolation and watch the components and your actual results instead.
A few specific things to ignore. Ignore any “Quality Score hack” that promises a quick jump; the score reflects real relevance, so there is nothing to game. Ignore a low score on a keyword that converts profitably, because a keyword at 6 that brings you cheap leads beats a keyword at 10 that brings you nothing. And do not pause keywords purely because their score is low; pause them because they waste money. Quality Score is a clue about efficiency, not a verdict on whether a keyword is worth running.
Does Quality Score Affect Your Cost?
Yes, indirectly, and this is the reason it matters at all. Your ad’s position is decided by Ad Rank, which is essentially your bid multiplied by your real-time quality signals (plus the expected impact of your ad extensions). Because quality is a multiplier, a more relevant ad can win a higher position for the same bid, or hold the same position for a lower cost per click. That is the “quality discount” in plain terms.
The practical effect is large. Two advertisers bidding the same amount can pay very different prices per click if one has strong relevance and the other does not. This is exactly why poor relevance shows up as an inflated cost per click, and why improving the three Quality Score components is one of the most reliable ways to bring costs down. If your clicks feel expensive, weak quality is a prime suspect, which is the thread we pull in why your Google Ads CPC is too high.
How to Improve Your Google Ads Quality Score
You improve the score by improving the three things it measures. Five moves do almost all of the work.
- Tighten your ad groups around one theme. Group closely related keywords together so a single, focused ad can speak directly to all of them. Sprawling ad groups dilute relevance; tight ones lift it.
- Write ads that echo the keyword. Use the keyword’s language in the headline and description so the ad clearly answers the search. This lifts both ad relevance and expected click-through rate.
- Match the landing page to the ad. Send the click to a page that delivers what the ad promised, quickly and clearly. A generic homepage hurts landing page experience; a focused page helps it.
- Clean up who you show to. Add negative keywords and tighten your match types so your ad only appears for relevant searches, which lifts expected click-through rate.
- Fix page speed and mobile experience. A slow or clumsy mobile page drags down landing page experience no matter how good the ad is. Speed is part of quality.
Do these and the score follows, because you have fixed the causes rather than the symptom. Give it time, though: Quality Score updates on accumulated data, so improvements show over days and weeks, not minutes.
What Is a Good Google Ads Quality Score?
As a rough guide, 7 and above is healthy, 8 to 10 is strong, and anything below 5 deserves a look. But “good” is always relative to intent and industry, and averages differ a lot between sectors, so do not treat a single benchmark as gospel. A high-commercial-intent keyword should sit higher; a broad, top-of-funnel term will naturally score lower.
The more useful question is not “is my score good” but “is this keyword efficient.” If a keyword at 6 converts at a cost per lead you are happy with, it is doing its job. If a keyword at 9 drains budget without converting, the score is flattering a loser. Use the number to spot weak relevance worth fixing, then judge the keyword on results. That is the whole point of the diagnostic.
The Nobody Cares Take
Quality Score is one of the most misunderstood numbers in Google Ads, because people treat a diagnostic like a trophy. They screenshot their 10s, panic over their 4s, and spend hours trying to move a number that was only ever a summary of relevance in the first place. The score is not the point. What the score is pointing at is the point.
Here is the honest version: if your ads are genuinely relevant to the searches you bid on, and your landing page delivers what the ad promised, your Quality Score takes care of itself and your costs come down as a side effect. Chase relevance, not the number. Tight ad groups, ads that match the search, pages that match the ad, and clean targeting will move the components that matter far more than any hack.
So when you next see a low score, do not treat it as a grade. Treat it as a map. It is quietly telling you which of the three levers, the ad, the keyword or the page, is letting you down, and that is genuinely useful. Fix the cause, ignore the vanity, and let the number follow the work.
Frequently Asked Questions
What is Google Ads Quality Score?
Google Ads Quality Score is a 1 to 10 rating Google assigns each keyword to estimate how relevant your ad, keyword and landing page are to the searcher. It is built from three components: expected click-through rate, ad relevance and landing page experience. A higher score signals a better match, which can lower your cost per click and improve ad position. It is a diagnostic, not a live auction dial.
What does Quality Score actually measure?
It measures three things, each rated Below average, Average or Above average: expected click-through rate (how likely your ad is to be clicked), ad relevance (how well your ad matches the search intent), and landing page experience (how relevant, useful and fast your page is). Those component labels tell you exactly which lever to fix, which is far more useful than the single number.
Does Quality Score affect my cost?
Yes, indirectly, through Ad Rank. Ad Rank is roughly your bid multiplied by your real-time quality signals, so stronger quality can win a higher position for the same bid or the same position for a lower cost per click. That means better relevance effectively earns you a discount. Two advertisers bidding the same can pay very different prices if their quality differs.
How do I improve my Google Ads Quality Score?
Improve the three things it measures. Tighten ad groups around a single theme, write ads that echo the keyword, send clicks to a landing page that matches the ad, add negative keywords and tighten match types so you only show for relevant searches, and fix page speed and mobile experience. These lift the underlying components, and the score follows over days and weeks.
What is a good Quality Score?
As a rough guide, 7 and above is healthy, 8 to 10 is strong, and below 5 needs attention, but it varies by industry and intent. More important than the number is whether the keyword is efficient. A keyword at 6 that converts profitably beats one at 10 that does not. Use the score to spot weak relevance, then judge each keyword on its actual results.
Is a low Quality Score bad if my ads still convert?
Not necessarily. A low score flags weaker relevance, which usually means you are paying more per click than you could be, but if a keyword converts at a cost per lead you are happy with, it is still doing its job. Do not pause a profitable keyword just because its score is low. Look at whether fixing the flagged component would lower your cost, and prioritise money over the number.
Does Quality Score apply to Performance Max?
Not in the same way. Quality Score is a keyword-level metric for Search campaigns, so you will not see a 1 to 10 score for Performance Max or other automated campaign types that do not use keywords. The underlying principles still apply, though: relevant creative and strong landing pages help automated campaigns just as they help Search, even without a reported score.
How long does it take to improve Quality Score?
It is gradual, not instant. Quality Score updates on accumulated performance data, so after you tighten ad groups, sharpen ads or improve a landing page, the score reflects the change over days and weeks as new impressions and clicks build up. Make the fixes, keep them in place, and give the account time to register the improvement rather than expecting an overnight jump.
