The below instruction summarizes the bidding strategies available. These bidding strategies are set at the advanced campaign setting:
Flat CPM Bidding:
This bidding strategy will always bid the CPM entered in the UI whenever it receives an ad requests that matches the accounts targeting. Because it’s in a second price auction, this means it will always submit the bid set in the UI, but if you win the auction you will only pay 1 cent more than the next highest bid.
Flat CPM with Pacing:
Similar to Flat CPM, this bidding strategy will also always bid the CPM entered in the UI whenever it receives an ad requests that matches the line item targeting. However, it must also have room remaining within its pacing target.
Optimized CPM with Pacing:
This bidding strategy will bid values between 10-20% lower than the base CPM entered in the UI. The strategy will still prioritize remaining on its pacing target through bidding frequency, but it will always bid lower than the base CPM.
CPC Goal (beta):
This bidding strategy will optimize towards a goal eCPC set at the line item level, as well as stay within the parameters of a max CPM bid set at the line item level.
