Does Exchange Bidding Work?

Google’s Exchange Bidding has landed! With the beta version having been rolled out across our publishers, the results are better than we could have imagined. We were delighted to present these results at the AdX Bootcamp in Sydney today to a packed room full of publishers.
Let’s start with the implementation. The implementation of Exchange Bidding is without a doubt one of the simplest implementations out. With Header Bidding, one of the major drawbacks for publishers has been the heavy dev work involved. The dev work is complex and often places a huge strain on small and medium sized publishers. We have put a lot of work into making this process as streamlined for publishers as possible and have come a long way.
Our simple 6-step guide
Google seems to have mitigated this limitation of Header Bidding. The Exchange Bidding implementation requires only one piece of code to be updated on the site. After this initial implementation, there are no tedious and complex code updates that need to be made to the site, as is regularly the case with Header Bidding.
Exchange bidding has immense power. The simplicity in terms of implementation extends to ongoing management and updates to the product. Rather than changes having to be made to the code on your webpage (which requires a lot of dev time), all optimisations from within DFP. In this way, Exchange bidding means that networks are being hosted within the Google product suite.
Google claimed that this product should result in a 40% CPM uplift for publishers. And based on the rollout of this product across our publishers, Google hasn’t come short on their promise. We’ve seen an impressive 43% CPM uplift on average, from the publishers we’ve rolled Exchange Bidding out on.
So how does Exchange Bidding actually work?
Exchange Bidding moves away from the typical code structure of ad serving and instead functions via a ‘server to server’ interaction. There are a few key steps involved:
When a user visits a site and an ad request is triggered and is sent to DFP
DFP then runs a unified auction to determine the ad that will generate the best yield.
This involves DFP selecting the best line item to compete in the auction and then sending a bid request to particular eligible yield partners. DFP collects the highest big from each partner.
The winning creative (after dynamic allocation and the Exchange bidding auctions) is displayed on the publisher’s site.
The server-to-server basis for this product means that page-load latency is also reduced.
