To help you with the ad request optimization to ad campaigns, Ad Server offers a Requests Optimization tool that could be found in the Campaign Advanced settings.
The algorithm analyses performance of the chain by the pre-selected options and its value every time picked in the Lookback period field - and caps the volume (if the value is doesn't match the threshold) of the traffic coming or, the opposite, remove capping (if the value matches the threshold) the volume of the traffic out of the chain.
Options (threshold by):
- fill-rate (Ad requests)
- eCPM
Condition:
- Less
- Less equal
- Greater
- Greater equal
Chains
- Fill rate value - Source + Bundle/Domain + Campaign;
- eCPM - Source + Bundle/Domain + Campaign
Example
Condition is set on campaign Y:
- Fill rate (Ad requests): 3%
- Condition: Less
- Lookback period: last 30 minutes
- Traffic cap for performance below threshold: 10%
Traffic goes from source X and 3 bundles (1,2,3) to campaign Y. If the Fill rate on the specific bundle chain (i.e. X-1-Y) is less than 3% for the last 30 minutes, the system will cap the amount of the traffic sent thru this chain to picked percentage in Traffic cap for performance below threshold field (10% in this case) of incoming traffic, which means that only 10% of requests will reach the campaign. If during a consequent check (every 15 minutes) the value of fill-rate on the chain X-1-Y reaches and overcomes the threshold (3%), the system removes the 10% limit.
