The programmatic media ecosystem has undergone significant transformations since its inception. Designed to simplify the process of connecting media buyers with their desired audiences, this ecosystem has adapted over time to address the evolving needs and concerns of publishers, advertisers and technology providers.
The Early Days: Second-Price Auctions
In its initial phase, most media was purchased through second-price auctions. In these auctions, the second-highest bidder would win, and publishers often felt as though this was a race to the bottom, leaving money on the table. This misconception persisted for two primary reasons:
1. Floor Setting: Publishers had the ability to set a floor price, thus controlling the minimum accepted bid.
2. Bidding Strategies: Smart buyers would bid higher to ensure a win, although they never intended to pay near their top bids.
Despite these safeguards, the second-price auction model led to a perceived lack of control and optimization on the publishers' part.
Transition to First-Price Auctions
A shift in the industry occurred as most auctions moved to a first-price model, where the winning bid was the price paid for the impression. This change allowed for a more direct relationship between bid and payment, leading to increased transparency and predictability in the auction process.
However, with this change came new challenges and opportunities for both buyers and ad-tech providers.
Innovations in Bidding Technology: Header Bidding and Bid Shading
The continuous pursuit of optimization led to the development of technologies like header bidding and bid shading.
Header Bidding: Also known as pre-bidding, advance bidding and holistic yield management, header bidding allows publishers to simultaneously collect multiple bids from various demand sources on all their ad inventory before a sale. This increases competition and potential revenue for publishers.
Bid Shading: DSPs and ad exchanges utilize bid shading technology to assist advertisers in paying the lowest possible price in first-place auctions. By leveraging market data, bid shading algorithms find an average between the highest and lowest-priced bids.
Transparency Issues and New Solutions
While these technologies brought advancements, they also led to new challenges. Many SSPs and DSPs used them to further obscure real media costs, building in margins and contributing to transparency issues. Platforms like Beeswax and The Trade Desk, for instance, not only charge for bid sharing but also take a percentage of the bid costs saved, thereby increasing media costs for buyers and reducing transparency.
The need for transparency has led to initiatives such as TAG (Trustworthy Accountability Group) and TrustNet's new transparency certification. Advertisers and agencies can now work with platforms that are certified for transparency, aligning incentives and fostering a more open and honest marketplace.
Today's programmatic ecosystem requires educated buyers who are committed to understanding how their dollars are spent. Through ongoing learning and leveraging transparency initiatives, stakeholders can navigate a landscape that continues to evolve. The industry's journey from second-price auctions to a focus on transparency illustrates the dynamic nature of the programmatic media landscape and underscores the importance of adaptability, innovation, and trust in shaping the future of digital advertising. Buyers can now work with a certified transparent partner to assure the largest portion of their dollar possible is being spent where it should be -- on media and business outcomes.
