You want to improve the relevance of an ad with a particular set of keywords. The goal is to increase the Ad Rank of the ad so it gets more exposure. What action should improve the ad relevance?

The selection is correct because adding more negative keywords directly improves ad relevance by preventing your ads from appearing on searches that are unrelated to your business, thereby tightening the thematic connection between your keywords and your ad copy. When you exclude irrelevant traffic, your click-through rate (CTR) typically increases because your ad is only shown to users whose intent matches your specific offering. Since ad relevance is a core component of Quality Score, and Quality Score is a primary factor in the Ad Rank calculation, filtering out mismatched queries ensures that Google's auction system views your ad as a high-quality, highly relevant result for the remaining search terms. This optimization allows your ad to compete more effectively in the auction, often achieving better placement and more exposure at a lower cost-per-click than ads cluttered by broad, irrelevant matches.
