Open auction pricing in programmatic advertising is a tactic used to expose a publishers inventory to the largest potential pool of advertisers. In an optimal real time bidding auction with revenue being the most important value, every single impression should be sold to the buyer who wants to pay the most. Many RTB ecosystems are driven by open auction pricing for the majority of all tiers of inventory.
Benefits of Open Auction Pricing Methodology
1000’s of advertisers competitively bidding on each impression – leads to high CPM’s
Diverse set of targeting and creatives to engage the user
Market dictates the value of the inventory
As demand increases, inventory becomes more scarce and valued which drives up the price of the bid
In an open auction pricing system, the buyer and seller usually do not have any direct relationship. The Lumascape offers a detailed, yet confusing depiction of how an ad impression flows from the advertiser to the publisher. Let’s simplify it down a bit for this example.
In the most basic explanation for open auction pricing advertiser dollar flows from a buyer who is an independent advertiser, agency trading desk or, demand side platform to an ad network that houses supply and demand in their system, to the publisher who receives the money for their inventory at every successful bid auction.
Once tags are implemented, the programmatic ecosystem begins to bid and optimize buyers with the end goal of generating the most revenue possible.
Negatives of this model
While showing your ad inventory to a variety of buyers at the same time and allowing a whole bunch of advertisers to bid, having this much “madness in an auction can lead to some issues.
Diluting the value of your ad inventory by selling at low prices
