When the functionality is enabled for your account, the default behaviour for creatives seen for the first time through real-time bidding is automatically set to "Blacklist". You can change this setting at any time. For more information, refer to Settings.
Creative Review enables you to review all the creatives seen through real-time bidding by playing them in the video player and then approving or rejecting them. This enables you to decide whether a bid containing a specific creative can win the auction or not. All necessary information related to the ad creative is listed below the player (Creative ID, DSP, Seat, Buyer, and Domain).
