An advanced programmatic advertising method allowing multiple ad exchanges to bid simultaneously for impressions.
Header bidding is an advanced programmatic advertising technique. Publishers place a piece of code in their website's header that allows multiple ad exchanges to bid on an ad slot simultaneously before the request is sent to the ad server.
Traditionally, ad inventory was offered in a "waterfall" sequence (Exchange A first, then B, then C). This meant Exchange C might be willing to pay $5.00, but never got the chance because Exchange A took it for $2.00. Header bidding flattens this, ensuring the highest bidder wins.
It increases revenue (yield) but can slow down page load times because the browser has to wait for multiple auction responses.
