Improved header bidding support in Google Ad Managerhttps://blog.google
Google Ad Manager is introducing new features to improve header bidding support. In just a few steps, publishers can make their ad space available to header bidders — similar to how they can specify what ad space they want to sell with Ad Exchange or Open Bidding. This will be opening to more publishers in beta soon.
They have also been adding additional reporting features to give publishers greater insights on header bidding performance.
