Capping
Frequency capping is a feature that limits the maximum number of ad impressions, which appear to a single user within a specific period of time. The feature is enabled to place the individual restrictions and can be found in a campaign configuration window, in the Optimization tab.
Frequency Capping
Frequency capping is set per device. Various devices identifiers (a unique device ID for mobile, and an IP address and User Agent data for desktop) are used in order to identify a user’s device.

Tip
Voluum Tip: The recommended default value is 6 times per day to ensure a sufficient sample of traffic for the testing period. Then increase the value once the campaign is optimized.
Impression Capping per Widget
In addition, impression capping per widget allows choosing the number of ads that can be displayed in the single native widget at once.
