Google announced a new enhancement to Conversion Optimizer “Target CPA Bidding,” that let you set a bid that reflects the average amount you’d like to pay for a conversion rather than the maximum you’re willing to pay for it. “To enable Target CPA bidding, visit the Settings tab in your account, select ‘Focus on Conversions,’ and click ‘Advanced Options.’ Note that Conversion Optimizer is only available for campaigns that have implemented conversion tracking and have received at least 15 conversions in the last 30 days. We hope that having the additional Target CPA bidding option will make it even easier for you to boost your AdWords ROI. Of course, if you’re happy using Max CPA bids with your Conversion Optimizer campaigns, then there’s no need to make any changes to your campaigns,” noted Google.
