Header Bidding (also known as header auctions, parallel bidding, or header bidding) is a technique that involves running SSP & Ad Exchange code directly on page so publishers can receive bids on their inventory that may be unavailable through their primary ad server and exchange. The returned bids are then passed into the ad server so they can compete with direct demand and the primary ad server's exchange on a level playing field.
Prebid is a free open source library and community that helps publishers implement Header Bidding on their websites & apps. In order to make your life easier we have released implementation examples of header bidding for Radiant Media Player through Prebid.js on GitHub. Those examples can also be found on prebid.org website.
A list of bidders that work with Prebid.js and with video ads support can be found here.
Implementation examples for using Prebid.js (both client-side adapter and Prebid Server) with Radiant Media Player are available on GitHub. In those examples, we will show how to set up Prebid to show a video ad from DFP. We will use Radiant Media Player and the AppNexus AST bidder, but the principles are the same across video-enabled bidders. Feedback and contributions are welcome.
