All payments are facilitated by Google and determined by each Open Bidding yield partner's impression delivery volume. Payments are sent to the publisher and requested from the buyer within approximately 30 days of the end of the month.
How buyers are charged for Open Bidding impressions
Buyers bidding through the Ad Exchange continue to pay according to the standard Ad Exchange auction model. When an Open Bidding yield group buyer wins the unified auction, the buyer pays the bid price.
How publishers are paid for Open Bidding impressions
Publishers are paid according to the terms of their Ad Exchange agreement and Open Bidding contract addendum. Payments for Open Bidding impressions are made net of Google's revenue share.
The publisher's bill from Google will include an itemized list, displaying revenue from Ad Exchange and third-party exchanges separately. Publishers can then use the yield group dimensions and metrics in Ad Manager reporting to itemize revenue per exchange or yield group.
