Answer

D. Quality Score directly affects Ad Rank by measuring ad relevance, expected CTR, and landing page experience

Explanation

In the Google Ads auction, Ad Rank is the formula used to determine your ad’s position and whether it will show at all, calculated by combining your max CPC bid with your Quality Score (and the expected impact of ad extensions). Quality Score is the 1-to-10 rating that acts as a major multiplier in this equation, grading your keyword’s overall relevance based on three core components: ad relevance, expected click-through rate (CTR), and landing page experience. Because of this direct relationship, a high Quality Score allows an advertiser to achieve a high Ad Rank—and therefore a top ad position—even if their bid is lower than a competitor’s.
