Truth and Transparency Key To Programmatic Growth

By: Jason Fairchild – CRO and Co-Founder

The advertising industry is in the early stages of a massive re-invention that will result in $640 billion in annual global ad spend being transformed to programmatic technology. This transformation started with display ads, but will eventually encompass every form of advertising, from TV, to outdoor, to in-car, to mobile to augmented and virtual reality. For this future to be realized, brands must have absolute trust using programmatic technology, where “trust” comes down to the need for full transparency into all aspects of programmatic ad buying.

We should start the conversation with an honest assessment of the shifting dynamics impacting the second-price auction in programmatic. The second-price auction has been a crucial component of the transparent, efficient digital marketplace since the beginning of programmatic. Today, the inherent fairness of this auction is under siege.

The simplest way to think about the second-price auction is to look at how millions of people around the world buy and sell items via eBay auctions. Sellers offer inventory by setting the lowest price they are willing to accept, and buyers share the highest price with eBay that they are willing to pay, believing that their price ceiling will be held in confidence, allowing for a fair and transparent auction to occur.

Historically, SSPs facilitated this kind of trusted environment by establishing “dynamic price floors” that help publishers achieve full and fair value for a given impression as if every interested buyer were able to compete in every auction and cast their bid. The sheer scale of today’s digital media landscape requires this approach due to the multitude of auctions happening at any given second in the day. Dynamic floors, which are the publisher equivalent to an advanced programmatic bidding algorithm, bring balance to the market. They create quality price support, and when done well, return second price discounts to buyers. This kind of win-win situation, where value is distributed simultaneously to the publisher and to the buyer, represents a core pillar of the quality programmatic marketplace and has helped fuel its growth into the $40 billion industry it is today.

These dynamics began to change as header bidding gained popularity which significantly altered the auction mechanics that had governed programmatic’s early rise. Now, a second-price auction could take a bid with a $20 maximum, clear it with a winning price of $5 (one penny above the next highest bid or dynamic floor) but then as it passes the winning bid into the ad server, it could potentially lose to a $7 bid – even though the original buyer was willing to pay $20. These dynamics were only exacerbated with the introduction of container technology that enables multiple header bidders to operate at once.

Rather than competing on their feature sets for a long-term partnership, exchanges/SSPs are now fighting one another on an impression by impression basis to maximize publisher yield. The result has been an unfortunate return to the wild west days of programmatic where buyers can no longer count on a standardized second-price auction every time they bid, and agencies and DSPs grapple with a suite of SSPs that all use different mechanisms to determine the winning bid.

While the long-term future of programmatic auction logic remains unclear, the near-term future is already revealing itself. In recent months, winning bidders who were used to paying out at a second-price saw clearing prices rise steadily towards those of a first-price auction. To ascertain how these auction dynamics began to dramatically shift, OpenX recently partnered with a single DSP to better understand the changes impacting the market.

The effort analyzed more than a million impressions through multiple exchanges across nearly a dozen sites and identified several SSPs that appeared to be deploying non-transparent first-price mechanics to significantly increase the clearing price. These exchanges, which know the buyer’s true highest price (“first-price”), were setting second-price rules that clear an auction at 95% (or higher) of a buyer’s first-price bid. While those auction mechanics may be more common at lower price points, where there is naturally more bid density, the same results occurred consistently for high value bids in the $10-$50 range.

For example, if a buyer was willing to pay $40 for an impression, and the typical dynamic price floors would have set the minimum price at $8 to allow for a fair auction to occur, several SSPs were found to have price floors set at 99% of the maximum value. They bid $40 expecting to pay something far less, and end up being “first priced” and paying $40. In short, the buyers were competing in what was essentially a shadow first-price auction, almost certainly without their knowledge.

While this practice may deliver short term gains to the publisher and SSP involved, it does so to the detriment of the buyer.
