The Three Components of Quality Score
Quality Score is determined by three factors, each rated as Below Average, Average, or Above Average. Expected CTR predicts how likely your ad is to be clicked. Ad Relevance measures how closely your ad matches the searcher's intent. Landing Page Experience evaluates how useful and relevant your landing page is after the click. All three components are evaluated relative to other advertisers competing for the same keywords. Improving any one component can lift your overall Quality Score.
