High costs may result from inefficient bidding strategies, overly broad targeting, or high competition in your niche. Adjust your bidding strategy—if using Target CPA or Max CPV, lower bids gradually.
Refine audience targeting to exclude irrelevant users. Use device targeting to focus on devices where your ad performs best. Also, test different ad formats (skippable vs. non-skippable) and use negative placements to avoid low-quality traffic. Monitor Quality Score to ensure your ad relevance is high, which helps lower costs.
