The AdWords Conversion Optimizer is a Google Ads automated bidding tool helping advertisers and marketers maximize conversions while maintaining target cost-per-acquisition (CPA). Here’s the basic mechanics: Instead of manual bidding strategies that focus on clicks or impressions, it prioritizes actions that actually matter–conversions. Now, once enabled, it will automatically adjust keyword bids to help you meet your set CPA target and searches that convert. How? Google uses your historical conversion data to predict which searches are likely to convert (and which won’t) and bids accordingly. To access this feature, you need to have conversion tracking in place and at least 15 conversions in the past 30 days.
