Quality Score is Google’s 1–10 rating of how relevant your keywords, ads and landing pages are. Higher scores generally mean better ad positions at lower costs. It is a diagnostic tool rather than a target, but improving the factors behind it almost always improves performance.
1The Three Components
- Expected click-through rate: how likely your ad is to be clicked
- Ad relevance: how closely the ad matches the search intent
- Landing page experience: how useful and relevant the page is
2Improve Expected CTR
Write headlines that include the keyword and a strong reason to click, use all relevant assets, and test ad variations. Pause keywords that consistently attract irrelevant searches.
3Improve Ad Relevance
Group keywords tightly by theme so each ad group’s ads can speak directly to those searches. A campaign that mixes ‘SEO services’ and ‘website design’ in one ad group will struggle.
4Improve Landing Page Experience
Send each ad group to a page that matches the search, loads fast on mobile, explains the offer clearly and makes it easy to convert. Avoid sending every ad to your home page.
5Keep Perspective
Quality Score is reported at keyword level and is an estimate. Focus on conversions and cost per lead; Quality Score improvements are a means, not the goal.
