Quality Score (Ads)
Quality Score is a 1-to-10 rating that ad platforms like Google Ads assign to your keywords, estimating the relevance and quality of your ads, keywords, and landing pages relative to a user's search.
In depth
Quality Score is built from three components: expected click-through rate, ad relevance, and landing page experience. The platform uses it as a multiplier in the ad auction, so a higher score can earn you a better ad position at a lower cost-per-click while a low score forces you to bid more for the same placement. It is diagnostic rather than a billable metric, meaning it tells you where the auction algorithm thinks your account is weak so you can fix the underlying experience.
A frequent pitfall is treating Quality Score as a vanity number and ignoring landing page experience, which is often the easiest lever to move. Tightly themed ad groups, ad copy that mirrors the keyword, and fast, relevant landing pages all push the score up. In a quiz-funnel workflow this is a natural advantage: sending paid traffic to a focused scorecard quiz that matches the search intent tends to improve relevance and engagement signals, which feeds back into a stronger Quality Score and cheaper, more qualified clicks over time.
Example in practice
Frequently asked questions
What three factors determine Quality Score?
Expected click-through rate, ad relevance, and landing page experience are the three signals. Each is rated as below average, average, or above average, and together they roll up into the 1-to-10 score.
Does Quality Score affect what I pay?
Yes, it acts as a multiplier in the auction, so a higher score generally lowers your cost-per-click for the same position. A low score means you must bid more to compete for the same placement.
How fast can I improve Quality Score?
Changes to landing pages and ad copy can influence the score within days to a few weeks as the platform gathers new performance data. The fastest wins usually come from improving landing page relevance and tightening ad group themes.
