Header Bidding is an advanced programmatic technology that allows publishers to offer their ad inventory to many demand partners simultaneously via a client-side or a server-side auction. This auction launches with a JavaScript tag placed on a header part of a webpage. It begins loading along with the page sending bid requests to all connected demand partners - SSPs, AdExchanges, ad networks, - before the ad server is called.
The Header Bidding Wrapper is a piece of JavaScript code that organizes all connected buyers and sets the rules for the auction. It is also known as a container or a framework. For web display ads, the header bidding code is placed in a web page's header, but there are cases when no JS code in the header is needed: video HB auctions happen in the video player while in-app and sometimes web display HB auctions are held on a server.
Here are the simplified version of how HB works for web display ads:
