True or False: A Deal ID allows buyers to engage in private deals with publishers through a real-time bidding infrastructure.

A Deal ID is indeed a unique identifier that facilitates private deals between buyers and publishers within the real-time bidding (RTB) infrastructure. It serves as a key that allows buyers to access specific inventory that has been negotiated directly with publishers, typically outside of the open auction environment. This means that when a buyer wants to participate in a private marketplace or a direct deal, they need to use the Deal ID to make their bids for that specific inventory.

Private deals are advantageous because they can provide buyers with exclusive access to high-quality inventory and enable more favorable pricing or terms. The process typically involves pre-negotiation between the buyer and publisher, and the Deal ID is how this agreement is executed in the actual bidding environment.

In contrast, options implying that a Deal ID does not facilitate private deals or suggests limitations that are inaccurate do not capture its core function in the ecosystem of programmatic advertising.
