A deal ID is primarily used in which type of advertising buy?

A deal ID is primarily associated with private marketplace buys. In this context, a deal ID serves as a unique identifier that enables buyers and sellers to transact within a secured environment where specific inventory is offered at a pre-negotiated price. This allows for more transparency and control in the buying process, as both parties can manage the terms of the deal, including pricing, inventory, and targeting, effectively facilitating a direct relationship.

In private marketplaces, inventory is typically limited to select advertisers, which distinguishes it from open auction environments where inventory is available to anyone willing to bid. The deal ID becomes an essential tool for streamlining these transactions, ensuring that both the publisher and advertiser have a clear understanding of the agreement.

In contrast, programmatic buys can include both open auctions and private marketplace transactions; however, the deal ID is specifically a hallmark feature of private marketplace deals. Therefore, identifying the correct use of a deal ID as primarily linked to private marketplace buys is crucial to understanding how digital advertising transactions are managed efficiently.
