Understanding Unified Auction and Its Distinction from Header Bidding

In the rapidly transforming world of programmatic advertising, two notable methodologies substantially changed the manner in which ad inventory was sold: Unified Auction and Header Bidding . Ultimately, they have revolutionized the digital advertising area, and marketers, as well as publishers, can use new methods to enhance their revenue and create more effective results. In this paper, Gray discusses what these terms are and distinguishes them from each other.

What Is Unified Auction?

A Unified Auction, also referred to as a single auction, is an advanced kind of header bidding. It allows all demand sources to bid at the same time. Then, all demand sources – Supply-Side Platforms , Demand-Side Platforms , ad exchanges, and other sources, both direct and programmatic, – take part in one auction, which guarantees that publishers get the maximum price for ad space.

Key Benefits of Unified Auction:

Higher Demand: As we can see, a unified auction helps a publisher to get more demand partners to a single auction, which, in its turn, increases demand partners, competition, and revenue.

Fair Competition: Google passes the competition on equal terms for itself and non-Google partners. Even while maintaining a separate market, non-direct demand partners can compete.

High Quality: Publishers can compete for higher-value demand and launch competition on their inventory that might have paid more CPMs even more than higher prices in possible direct agreements.

How Is It Different from Header Bidding?

In a nutshell, Header Bidding is a programmatic advertising method that allows publishers to expose their ad slots to multiple ad exchanges and demand partners simultaneously. It is a JavaScript code that is commonly placed in the header of a website and operates on the client-side . The header bidding function sends a call to all demand partners at once, gathers their prices and sends them to the ad server to complete the decision process.

Distinctive Features of Header Bidding :

  • Multiple auctions on the client side to fill the ad space.
  • Transparent and competitive: this brings transparency as well as competition into the ad bidding process. Thus, publishers can see what type of demand source is ready to bid the highest.

The Key Differences:

· Auction process: Header bidding conducts several client-side auctions. In contrast, the unified auction one conducts a server-to-server auction where the ad server , usually Google Ad Manager, handles the whole process from the onset of sending ad requests to the display of the ad to the user. Server-to-server auctions may involve hard timeouts whereby the deadline is met irrespective of whether the winning bid has been determined.

· Efficiency: Unified auctions are more efficient than header bidding auctions since it eliminates the numerous client-side auctions to be conducted. Thus, the unified auctions reduce server calls, making the ad serving process efficient. Due to page latency issues, some client-side auctions are estimated not to bring about revenue thus wasting the bid opportunity.

Conclusion

In conclusion, both unified auctions and header bidding have its advantages and may help to achieve better ad revenue. The choice between them may be left at the discretion of publishers and advertisers, depending on their preferences and goals. As the industry develops and improves, the combination of the most effective features of existing methods is likely to appear, which will open up new opportunities for advertising.
