Bid Filtering
Also: Traffic shaping; Pre-bid filtering
Sellers and DSPs discarding bid requests before the auction to save cost: requests unlikely to be bid on, from blocked sites, or failing quality checks. Shaping means a buyer's targeting is applied to a pre-filtered stream, not to all inventory.
