An advertiser wants to improve their position without necessarily increasing their bid. Which action would most directly impact their rank?

Refining the quality and relevance of the ad and landing page directly improves your Ad Rank, which determines your ad's position. Ad Rank is calculated using your bid, the components of Quality Score (expected clickthrough rate, ad relevance, and landing page experience), and the expected impact of your ad extensions and other ad formats. By enhancing ad relevance and landing page experience, you boost your Quality Score, leading to a better ad position even without increasing your bid. Adding more exact match keywords might expand reach but doesn't inherently improve rank for existing keywords. Increasing campaign name length and switching billing methods have no impact on Ad Rank.
