What is a private marketplace (PMP) and when would you use it?

• A. A negotiated, invitation-only programmatic auction with premium publishers; used for brand safety, premium inventory, and stronger guarantees.
• B. Public auction open to anyone.
• C. A marketplace only for offline ads.
• D. A partnership with one advertiser.

Answer: (A)

Private marketplace is an invitation-only, programmatic environment where premium publishers make inventory available to a select group of buyers. It combines the efficiency of automated bidding with the quality and control of direct deals. Advertisers can negotiate terms, set floor prices, and access exclusive, brand-safe placements that aren’t typically available in the open exchange, often with greater transparency and stronger guarantees on where ads appear and how they perform. Use it when your goals include premium context, tighter brand safety controls, and more predictable guarantees for inventory and placement. It’s ideal for campaigns where you want high-quality publisher partners and a more controlled, one-to-one-feel within a programmatic framework. The other options don’t fit: a public auction is open to many buyers and lacks the invitation-only exclusivity; offline ads are not digital programmatic inventory; a partnership with one advertiser describes a direct deal, not a marketplace that multiple buyers can access.
