One of our customer’s best bidders generates 250K€ annual ad revenues per year.
Thanks to Pubstack, this publisher implemented a discrepancy analysis workflow to compare his prebid performance against each bidder’s report.
The analysis shows that there is a 15% revenue delta between the bidder’s reporting and what Pubstack calculates.
This allows us to easily conclude that the bidder bids in gross amounts instead of bidding in net amounts just like all the other bidders. Which gives him a clear and unfair competitive advantage over the other bidders. He wins impressions that he shouldn’t be winning.
How do we spot it ?
After checking in the wrapper setup and a discussion with the bidder’s account manager, the publisher becomes sure that the discrepancy comes from Net vs. Gross bids.
A bid adjustment module is set. In this case, the bid adjustment module will scale down the bid before it enters the auction to make sure the bidder’s revenue share has been removed.
