Header Bidding for Mobile Buyers

What is Header Bidding?

Header Bidding technology makes the publisher ad supply available to both direct-sold and programmatic demand in a unified auction. Header Bidding eliminates the ad serving waterfall by enabling publishers to serve ads to the highest bidder - regardless of whether it’s bought directly, through a deal ID or through the open exchange.

Benefits of Header Bidding for Buyers

DSPs and advertisers get access to premium inventory and audiences that were historically reserved for direct-sold campaigns.
