Frequency Capping refers to the number of times your ads appear to the same person in one day from an AdRoll campaign.
By default, your Frequency Caps are automatically optimized by BidIQ, AdRoll’s proprietary real-time bidding algorithm. BidIQ processes hundreds of variables for each and every user to determine whether or not to bid, and how much, at the time of each potential impression.
You may also specify your own Frequency Cap in a web campaign. Note that turning on Frequency Capping opts your campaign out of an important optimization lever that BidIQ would otherwise manage automatically. This will result in lower performance and/or under delivery.
To make adjustments to Frequency Capping, edit your campaign and within the Campaign Settings and click Advanced Options to expose the Frequency Capping setting.
