Quality Score is the number most advertisers have heard of and few can explain. It gets treated either as a vanity metric to ignore or as a target to obsess over, and neither is right.
What it actually is: a 1–10 diagnostic, reported per keyword, that estimates how relevant your ad and landing page are to what someone searched. It does not directly set your costs — but the signals behind it do, and that distinction is where most of the confusion lives.
The three components
Quality Score is built from three inputs, each rated Below Average, Average, or Above Average against other advertisers bidding on the same keyword:
- Expected click-through rate — how likely your ad is to be clicked when shown for this keyword, relative to competitors. This carries the most weight.
- Ad relevance — how closely the ad copy matches the intent of the search.
- Landing page experience — whether the page delivers what the ad promised, loads quickly, and works on mobile.
The comparative framing matters. A Below Average rating does not mean your ad is bad in isolation; it means it is underperforming the other advertisers competing for that keyword. In a crowded auction you can improve everything and still sit at Average.
What Quality Score actually changes
Google ranks ads by Ad Rank, not by bid. Ad Rank combines your bid with ad quality signals, plus context like the search terms, device, and location. Two consequences follow, and they are the entire practical case for caring:
- You can outrank a higher bidder. A more relevant ad at a lower bid can take a better position than a less relevant ad at a higher one.
- You pay less for the same position. Because the auction accounts for quality, stronger relevance lowers what you actually pay per click.
That second point is why Quality Score belongs in any conversation about budget. Two accounts spending the same amount in the same industry can buy substantially different volumes of traffic, and relevance is usually the reason. I covered the budget side of this in how much you should spend on Google Ads in the Philippines.
What it does not do
Quality Score has no effect on your organic rankings. It is an advertising metric that exists only inside Google Ads, and improving it does nothing for SEO.
It also is not an account health score. A low Quality Score on a keyword you barely spend on is not a problem worth solving. The metric is only actionable where the money is.
How to improve each component
Expected CTR. Tighten the match between keyword and ad. Ad groups containing thirty loosely related keywords cannot produce ads that feel specific to any of them. Fewer keywords per ad group, with copy written for that exact intent, is the single most reliable fix.
Ad relevance. Get the searched phrase into the headline — not stuffed, but present. If someone searches for a specific service in a specific city, an ad naming that service and city will beat a generic brand message almost every time.
Landing page experience. Send the click to a page about the thing that was searched for, not the homepage. This is the most commonly ignored of the three and often the easiest to fix. Speed counts here too, which is why the real cost of a slow website applies to paid traffic as much as organic.
Why chasing 10/10 is a mistake
Quality Score is a diagnostic, not a goal. A keyword sitting at 7 that converts profitably is worth more than a keyword at 10 that converts nobody.
The productive use is triage: sort keywords by spend, look at the ones consuming real budget with Below Average components, and fix those. Ignore the rest. Perfect scores on low-volume keywords are a way to feel busy without changing the outcome.
And the number that ultimately matters is not Quality Score at all — it is cost per acquisition against customer value. Working out whether the account is genuinely profitable is a separate exercise, which I walk through in the 15-minute profitability check.
Key takeaways
- Quality Score is a 1–10 diagnostic per keyword, built from expected CTR, ad relevance and landing page experience.
- It is comparative — you are rated against other advertisers on the same keyword, not against an absolute standard.
- Higher relevance lowers what you pay per click and can outrank higher bidders through Ad Rank.
- It has no effect on organic rankings whatsoever.
- Fix it only on keywords consuming real budget; chasing 10/10 across the account wastes time.
Frequently asked questions
What is a good Quality Score?
Seven or above is healthy for commercial keywords. Below five on a keyword taking meaningful spend is worth investigating. Context matters more than the number — competitive industries run lower across the board.
How quickly does Quality Score update?
It recalculates as the keyword accumulates impressions and clicks, so changes appear over days rather than instantly. A brand new keyword shows an estimate based on account history until it has real data of its own.
Does pausing a low Quality Score keyword help the account?
Not directly — there is no account-wide score being dragged down. Pausing helps only if that keyword is spending money without converting, which is a performance decision rather than a Quality Score one.
Does Quality Score affect Performance Max campaigns?
Not in a form you can see. Quality Score is reported at keyword level in Search campaigns, and Performance Max does not expose keyword-level diagnostics. Relevance between the asset and the query still matters; you just cannot inspect it the same way.
