Header Bidding

What is Header Bidding?

Header bidding via the Underdog Media adapter is approved and available through PreBid.JS. With the Underdog Media adapter, you will access multiple demand platforms and have consolidated reporting and deep-dive analytics via our Custom Analytics.  Because we serve over 2 billion monthly impressions and have solid relationships with the exchanges, we provide access to bidders / advertisers that are not available to an individual site within the same exchange.
