An ad-relevance rating.

"Improving the landing page lifted the quality score and cut cost per click."

Definition in plain terms

Quality Score is Google Ads' diagnostic rating, from 1 to 10, of how relevant and useful your ad and landing page are to the person searching. It rolls up three signals: expected click-through rate, ad relevance to the keyword, and landing-page experience. A higher score signals the ad genuinely matches intent.

The mechanics

Quality Score feeds Ad Rank, so a higher score lets you win better positions at a lower cost per click — the platform rewards relevance because relevant ads keep searchers happy. You raise it by tightening the keyword-to-ad-to-landing-page match, improving expected CTR, and making the landing page fast and on-topic. It's a diagnostic, not a direct dial you set.

When it matters

Quality Score matters because it directly affects what you pay and where you show: two advertisers can bid the same and the one with the higher score wins a better slot for less. Chasing the number itself misses the point — it's a proxy for relevance, so improving the actual ad-and-page experience is what moves it and lowers cost.

Worked example. Two advertisers bid $2 on the same keyword. One has a tightly matched ad and a fast, on-topic landing page (Quality Score 9); the other points a generic ad at its homepage (score 4). The high-score advertiser wins a higher position and pays less per click — because the platform rewards the relevance that keeps searchers clicking.

Failure modes to watch. Treating Quality Score as a vanity number to game rather than a relevance proxy; sending ads to a generic homepage instead of a matched landing page; cramming unrelated keywords into one ad group; and ignoring landing-page speed.
