A direct campaign will claim exposure across the zones in which it is assigned according to its priority. Four different priorities exist
Exposure order relative to other campaigns of same priority
Will deliver evenly over time
|Will occupy exposure to deliver evenly across time to reach campaign goals
|Set weight will determine order
|Will occupy exposure relative to its revenue earning (eCPM)
|eCPM will determine order (higher to lower)
|Might deliver quickly (if high eCPM), or slowly (if low eCPM)
|Will occupy remaining exposure
At any given moment an ad is to be selected for a zone, all guaranteed campaigns in the zone will have their needed fill rate. Next comes the eCPM optimized campaigns. These campaigns will be prioritized in order of their eCPM, so the campaign in the zone with the highest eCPM will always be shown first, until its frequency cap is exhaused, then the next best eCPM campaign ad, and so on. This will be made with no regard to smooth out the delivery of the eCPM-optimized campaign over its dates.
If there are several guaranteed campaigns active, these might consume all capacity available in zones, and leave little room for eCPM campaigns to deliver.
All target settings will be applied regardless of priority - including frequency capping and geo-targeting.
