Question: What is the key difference between a Private Auction (PA) deal and a Preferred Deal (PD) on Amazon DSP?
- Private Auctions have a varied CPM, while Preferred Deals have a fixed price
- Private Auctions have a fixed price, while Preferred Deals have a floor price
- Private auctions offer preferred placement and custom execution, while Preferred Deals offer competition among diverse buyers
Explanation
Private Auction deals use auction-based pricing, so the final CPM can vary based on buyer competition. Preferred Deal inventory is accessed at a fixed negotiated price in Amazon DSP. Both deal types can provide more controlled inventory access than open auction buying, but they differ in pricing mechanics. The key distinction is flexible auction pricing versus fixed-price access.
Why the other options are incorrect
Fixed price is incorrect because Private Auction deals do not use fixed pricing.
Preferred placement is incorrect because that description does not match the pricing-based distinction between Private Auction and Preferred Deal.
