Header bidding, also known as advance bidding or pre-bidding, is an advanced programmatic technique wherein publishers offer inventory to multiple ad exchanges simultaneously before making calls to their ad servers. The idea is that by letting multiple demand sources bid on the same inventory at the same time, publishers increase their yield and make more money.
