Google Ads Quality Score Explained: Why It Affects Your Cost Per Click
Digital Marketing · Google Ads · Updated 2026
What Is Google Ads Quality Score?
Quality Score is Google’s 1-10 rating of how relevant your keyword, ad, and landing page are to a searcher, calculated from three components: expected click-through rate, ad relevance, and landing page experience.
| Component | What It Measures |
|---|---|
| Expected CTR | How likely your ad is to be clicked compared to competing ads for the same keyword |
| Ad Relevance | How closely your ad copy matches the intent behind the keyword |
| Landing Page Experience | How relevant, useful, and fast your landing page is for that specific search |
Why It Affects Your Cost
A higher Quality Score can lower your cost-per-click for the same ad position, because Google factors it directly into Ad Rank alongside your bid. Two advertisers bidding the same amount can pay very different prices depending on Quality Score.
How to Improve It
Group keywords tightly by theme so ad copy can speak directly to each one, write ad copy that mirrors the actual search intent, and make sure the landing page delivers exactly what the ad promised — not a generic homepage.
