Private Auction FAQ
- Access to premium inventory not available on the Open Auction
- Access to inventory before other buyers on the Open Auction
Inventory sold through a Preferred Deal goes to the single participating buyer, as long as the buyer bids at or above the negotiated fixed price. If the buyer’s bid is above the fixed price, the buyer still pays only the fixed price.
The inventory clears to the highest net bidder who bids above the impression minimum, in the Private Auction (see more details on the auction).
No, in a Private Auction the buyer pays the applicable minimum price or higher.
Yes, unless the publisher has explicitly blocked all other buyers from seeing this inventory.

Private Auctions work like any other auction on DFP. DFP runs an auction and determines if the Private Auction bid is higher than the DFP bid. If the Private Auction bid is higher, it will win and serve.
