SmartCPM is a pricing model that automatically adjusts bids for each ad placement depending on the competition. You spend less when there's no need to bid higher while never jumping over the payout cap you set.
💡 The pricing uses the second-price auction logic. After you determine a bidding cap, the algorithm starts competing for traffic within your targeting. Once it estimates the overall competitors’ bids, it will offer the highest payout needed to win the auction without jumping over the initial cap. But you will only pay a bit above the second-highest CPM in the auction.
