Win Rate Metrics

Win rate metrics help you to understand what number of incoming bid requests meets the targeting criteria of your DSP campaigns, how many times your ad was displayed and show you the percentage of won auctions. By analyzing the data you know when to increase your bids in order to get more traffic on your campaign. You can find Internal bids, Total bids, Impressions, Win rate and eCPM columns by accessing the Campaigns tab.

I. Internal bids

It's a number showing how many times your campaign took part in the internal auction. If it's higher than the number of Total bids, it means that other campaigns within Voluum DSP with a higher bid were selected.


II. Total bids

It's a number showing how many times your campaign won an internal auction and took part in the external auction.


III. Impressions

It's a number showing how many times your campaign won an external auction and your ad was displayed to a user.


IV. Win rate

Win rate is a percentage of traffic your campaign won in an external auction. You need to keep in mind that it does not take into account high volumes of traffic your campaign did not qualify to bid for due to campaign adjustments, targeting, or bid floors. The win rate cannot indicate in any way that you are bidding on all available traffic in Voluum's network.



It’s an effective CPM rate. It means the actual cost per thousand impressions. Keep in mind that as per mechanics of RTB and second-price auction, which our platform operates on, your bidding price is not always what you pay for every 1000 impressions. In a first-price auction you pay exactly what you set as the max bid for your campaign. In a second-price auction you pay $0.01 more than the second-highest bid (ex. you win with a $2 bid, second-highest bid after you is $1 thus you pay $1.01).
