What Is Quality Score?

Quality Score is Google Ads' 1–10 rating of the overall quality and relevance of a keyword, its ads, and its landing page, benchmarked against other advertisers competing for that same keyword. It's a diagnostic metric rather than a bid, but it directly influences both ad rank and cost per click, making it one of the more consequential background scores in a Google Ads account.

How is the quality score calculated?

Quality Score is calculated from three components, each rated as Below Average, Average, or Above Average: Expected CTR (how likely the ad is to be clicked for that keyword, relative to competitors), Ad Relevance (how closely the ad's message matches the keyword's intent), and Landing Page Experience (how relevant, transparent, and easy to navigate the destination page is). These three ratings combine into the overall 1–10 score visible at the keyword level.

Quality Score then feeds into Ad Rank, the calculation that determines both whether an ad shows at all and in what position, alongside the bid amount. This is the mechanism through which quality, not just budget, earns an advertiser a better position at a lower cost.

Examples & Use Cases of Quality Score

  • Two advertisers bid the same ₹50 for the same keyword; the one with a Quality Score of 8 pays a noticeably lower CPC for the same ad position than the one scoring 4, because the platform rewards the more relevant, higher-quality ad.

  • An account discovers a specific keyword scoring 3/10, and diagnosis shows Landing Page Experience rated Below Average, the ad sent traffic to a general homepage instead of a page matching the keyword's specific product.

  • A retailer restructures a broad, loosely themed ad group into several tightly themed ad groups, each with copy written specifically for its keywords, and sees average Quality Score across those keywords rise from 5 to 8.

Core Components of Quality Score

Quality Score is frequently conflated with just one of its own components, Ad Relevance, which is only one of the three inputs. It's also distinct from impression share: Quality Score affects whether and how cheaply an ad wins a given auction, while impression share measures how much of the total available auction volume an ad is actually winning across the board.

Why QC Matters?

Quality Score is one of the few account levers that improves both performance and cost at the same time, unlike raising a bid, which only ever costs more, improving Quality Score through tighter ad groups, more relevant copy, and a better-matched landing page can lower CPC while improving ad position. It's also a genuinely useful diagnostic: a low score on a specific keyword usually points to a specific, fixable gap rather than a bidding problem, and it's a core part of improving ROAS on Google with AI.

Frequently Asked Questions

Can I see my Quality Score for every keyword?
Yes, Google Ads displays it (along with the three component ratings) in the keyword-level reporting columns, though it isn't shown by default and needs to be added to the view.
Does Quality Score exist on platforms other than Google Ads?
The exact "Quality Score" name and 1–10 scale is specific to Google Ads, but most major ad platforms use some form of ad relevance or ad quality rating that similarly affects cost and placement.
What's the fastest way to improve a low Quality Score?
Tightening ad group themes (fewer, more closely related keywords per group) and rewriting ad copy to include the actual keyword language usually moves Ad Relevance quickly; matching the landing page content directly to the ad and keyword helps Landing Page Experience.
Does a low Quality Score mean an ad won't show at all?
Not necessarily, a low score can still show, especially with a high enough bid, but it will generally cost more per click and rank lower than it would with a stronger score.
Does Quality Score reset if I pause and restart a keyword?
It can be affected, since Quality Score is based partly on recent historical performance, a long pause can mean the score rebuilds from less recent data once the keyword resumes.
Is Quality Score the same thing as Ad Rank?
No. Quality Score is one input into Ad Rank, alongside the bid amount and the expected impact of ad formats and extensions. Ad Rank is the final calculation that determines position and eligibility.
