“Xandr’s Prebid Server protocol allowed us to bypass AMP’s technical limitations and maximize the competition for our inventory. This empowered us to optimize CPMs and load times on our highly visible AMP inventory, two of our company’s most important goals.”

Ouest-France chooses Xandr’s Prebid Server on AMP Inventory
Ouest-France selected Xandr to implement Prebid Server on AMP inventory. Whereas a client-side header bidding implementation uses a browser to make calls to demand partners simultaneously, Ouest-France opted for a server-side header bidding implementation, which uses a Xandr server to handle auctioning and decisioning away from the page. By moving the header bidding auction to a remote Prebid Server, Xandr empowered Ouest-France’s demand partners to both compete for every impression on even footing and reduce latency by speeding up page load times. By doing so, Xandr enabled differentiated demand and scale to unlock the full value of Ouest France’s inventory.
As a result, Ouest-France increased competition for every one of its fast-loading, highly visible impressions, driving a rapid increase in its CPMs.
Best of all, Ouest-France was able to achieve this success without operational roadblocks. With the help of the world-class Xandr customer service team, the company enjoyed a painless implementation process that only took a month.
Ouest-France increases global publisher revenues and doubles its AMP Inventory CPMs
Prebid Server on AMP inventory transformed OuestFrance’s mobile monetization. By increasing competition with header bidding, Ouest-France was able to maximize the yields it earned from its AMP inventory. The firm’s server-side prebid implementation allowed it to double its average CPMs from $1.5 to $3 – without an increase in latency. Within three months of implementation, Prebid Server was responsible for nearly 20% of Ouest-France’s monetization of certain ad units. All of this made Ouest-France’s inventory more attractive to buyers, raising its global publisher revenues in the process
