IPONWEB’s Optimal Price Discovery Service to Help Media Buyers Combat Programmatic’s Shift to First Price Auctions

Apr 11, 2019

Google’s shift to first price auctions creates more transparency for media buyers and sellers—but the financial risk for advertisers or tech platforms that aren’t yet prepared to bid in a first-price environment. 

IPONWEB is promoting its Optimal Price Discovery service to help programmatic buyers bid effectively in the first-price world. Buy-side partners currently using the tool are seeing a 15% to 30% reduction in media costs.


What is bid shading?

In second price auctions (which have been the predominant auction type in programmatic since its inception), buyers bid high on an impression to win, but pay only one penny more than the second-highest bid. This minimizes the risk of overpaying for media. Today, programmatic auctions are increasingly shifting to a first-price model, where the winner pays the amount they bid; depending on their bid strategy, this may result in overpaying. 

Bid shading provides a way for buyers to participate in first-price auctions with greater confidence that they aren’t overpaying for media. This technique takes into account a number of variables about any given programmatic auction—publisher, ad size, device, geo-location, platform, etc—and calculates a new (lower) maximum a buyer needs to bid, without reducing their probability of winning the auction. In this scenario, buyers are more likely to feel satisfied with the value exchange when they win the auction than if they had paid the first-price cost.  

Effective bid shading requires access to massive amounts of constantly changing bidstream data, sophisticated machine learning capabilities to make sense of that data, and accurate predictive technology that can reduce the amount an advertiser bids on specific inventory without hurting their ability to still win the auction. 

The bid shading built into most major DSP’s platforms presents a black box to buyers, while the accuracy and effectiveness of bid shading tools are not consistent across platforms, creating reporting and measurement issues for agency and brand buyers.


IPONWEB’s Optimal Price Discovery tool – the details

IPONWEB’s Optimal Price Discovery solution helps programmatic buyers bid effectively in first-price auctions as well as any auction environment not running a true second-price. The Optimal Price Discovery engine integrates with any DSP using OpenRTB protocol. 

Once integrated, a DSP identifies an impression opportunity on which it wants to bid, forwards its YES bid to the Optimal Price Discovery engine, which evaluates bidstream data against historical win data to make a prediction on the optimal bid price needed to win the auction. This optimized bid is passed back to the DSP, which returns it to the SSP — all in under 5 milliseconds. 

Optimal Price Discovery uses ongoing A/B testing to continuously monitor its bid optimization accuracy and effectiveness. This assures media buyers that they are securing the desired inventory at a fair price across all of their preferred platforms, without sacrificing performance, inventory quality, or campaign delivery.
