Private Marketplace
PMP
An invitation-only auction run by a publisher for a curated set of buyers, sitting between the open exchange and a direct Programmatic Guaranteed deal. PMPs give advertisers better brand-safety, inventory quality, and data signals than open auctions, while publishers capture higher CPMs than open-market monetisation. Access is controlled through a Deal ID agreed between the publisher and the buyer.
How Private Marketplace works in practice
Private Marketplaces give buyers access to a curated pool of publisher inventory that is not exposed to the open exchange, with better data signals, brand safety, and placement quality than open-web programmatic. Pricing is typically first-price auction inside a negotiated floor; only buyers holding the matching Deal ID can bid. PMPs are the middle ground between the maximum flexibility of open auctions and the maximum certainty of Programmatic Guaranteed — you still compete on bid, but you compete against a short list rather than the whole market. For advertisers in regulated industries (finance, healthcare, crypto) PMPs are often the only way to reach premium publishers who will not sell them inventory through open exchanges.

Let's talk →This term sits in the Paid Media category, which means it is most useful when evaluating paid campaigns, auction dynamics, targeting control, and media efficiency.

Automated buying and selling of digital advertising inventory through real-time bidding platforms. Programmatic enables precise audience-level targeting across thousands of publisher sites simultaneously, replacing manual direct insertion orders. Demand-Side Platforms (DSPs) such as DV360, The Trade Desk, and Amazon DSP are the primary execution tools.
A direct deal type in programmatic advertising where a publisher reserves a fixed volume of impressions for a buyer at a fixed CPM, executed through the DSP/SSP pipes rather than open-market auctions. PG combines the reach and workflow of programmatic with the inventory certainty of a traditional direct buy. It is the preferred format for brand campaigns where reach targets, frequency control, and premium placements must be guaranteed.
A unique identifier that unlocks access to negotiated programmatic inventory between a specific publisher and buyer — whether in a Private Marketplace auction or a Programmatic Guaranteed deal. The Deal ID passes pricing, placement, and data permissions through the bid request so the DSP can transact at the agreed terms. Misconfigured Deal IDs are a common cause of campaigns under-delivering against contracted volumes.
Brand safety refers to controlling where ads appear so a brand is not shown next to harmful, misleading, or unsuitable content. It is a core consideration in display, video, and programmatic advertising where inventory quality can vary significantly.
