What is Header Bidding and why you should use it?
Header bidding is a technology which allows to run a realtime auction on publisher's side. This decrease page latency and increase the CPM rates.
When page is loaded the script in the header sends out bid requests to ad partners simultaneously, gets bids for ad spot and shows ads at the highest rate. If no bids return standard waterfall setup is initiated.
So, you can run both header bidding and traditional waterfall ad serving setup on the same page.
How do I put it on my site?
You will need to create and tune a wrapper, the .js script. It is a core script that sends out requests and collects the bids. That's also required to build and put somewhere the prebid.js as well as integrate all parts together and add them to the header of your website.
With Headbidder.net, now, publishers are able to manage all bidders added from the single Headbidders' GUI, it simplifies the whole Ad Operations process related to Prebid.js usage.
