Google Ads Quality Score Explained

Quality Score is Google Ads' 1-10 rating of how relevant and useful your ad, keyword, and landing page are to someone searching that term. It isn't a ranking factor you pay directly for, but a higher score typically means lower costs per click and better ad positions for the same bid.

The Three Components of Quality Score

Google calculates Quality Score from three signals, each shown in your account as Below Average, Average, or Above Average.

Expected Click-Through Rate

This measures how likely your ad is to be clicked when it shows for a given keyword, based on historical performance. Tightly themed ad groups with closely matched keywords tend to score well here.

Ad Relevance

This looks at how closely your ad copy matches the intent behind the keyword. An ad group covering too many unrelated terms usually drags this score down.

Landing Page Experience

Google evaluates whether your landing page is relevant, easy to navigate, and loads quickly on mobile and desktop. A slow or unrelated page can undo strong ad copy and keyword targeting.

Why Quality Score Matters for Your Budget

A few practical ways Quality Score affects what you actually pay:

• Higher Quality Score keywords often achieve lower cost per click for the same ad position.

• Low scores can make some keywords too expensive to run profitably, even with unlimited budget.

• Improving your landing page quality is often the fastest way to lift a struggling score.

• Reviewing Quality Score by keyword monthly helps you catch problems before they waste budget.

For Google's own explanation of how the score is calculated and displayed, see the official Quality Score guide.

FAQ

Is Quality Score the same as ad rank?

No. Quality Score is one input into ad rank, which also factors in your bid, the expected impact of ad extensions, and auction-time context.

Can a new keyword have a Quality Score?

New keywords often show no score until they accumulate enough impressions, though Google may estimate one based on similar keywords in your account.

Does a low Quality Score stop my ad from showing?

Not directly, but it raises the cost needed to compete for the same position, which can price you out of valuable auctions over time.

How quickly can Quality Score improve?

Changes to ad copy or landing pages can shift scores within days to weeks, since Google needs fresh performance data to recalculate the rating.
