What is a PMP deal, and when should you use one?

A line on the media plan says the in-store campaign will run "via PMP." What did you just agree to? A PMP, or private marketplace, is an invitation-only programmatic deal: a media owner offers inventory to a specific buyer on agreed terms, and the buy executes through the buyer's demand-side platform (DSP) under a deal ID. You get programmatic workflow with a known seller and known inventory.

That combination of automation and certainty is why the PMP has become a fixture in digital out-of-home plans. Here's how it works and when it earns its place.

How is a PMP different from the open exchange?

On the open exchange, inventory is offered to any qualified bidder through an auction, and the buyer often can't say in advance exactly which screens or sites will carry the ad. A private marketplace inverts that. The seller and buyer know each other, the inventory is scoped up front, and the terms are set before a single play runs. The deal ID is the handshake that connects the agreement to the DSP.

In DOOH, where the inventory is physical screens in specific venues, that certainty carries extra weight. You're not buying an abstract impression; you're buying presence in a particular kind of place.

Most PMPs also come with transparency the open exchange can't match. The buyer can see exactly what inventory the deal covers before committing, and the seller treats the deal's buyer as a known partner rather than an anonymous bidder. For a planner, that's the practical difference: you can put a PMP on a plan and describe precisely what it buys.

What does a PMP deal actually contain?

A DOOH private marketplace deal typically specifies four things: the inventory, meaning which screens, venues, and geographies; the flight window; the agreed terms; and the deal ID that ties it all together inside the DSP.

On the NRS Digital Media network, a PMP can carry the same targeting available on a direct buy: audience index, retail channel, SKU-level activation (a SKU, or stock-keeping unit, is the identifier for one specific product), or geography down to the zip code. The screens themselves run on NRS point-of-sale systems in 34,000+ independently owned stores.

When is a PMP the right call?

Three situations favor it. Your team already runs media through a DSP and wants in-store screens inside the same reporting and pacing workflow. You're coordinating several channels and want budget and frequency managed in one place. Or procurement prefers consolidated programmatic billing over one-off insertion orders.

In each case, the PMP lets in-store media behave like the rest of your digital plan. That's the whole appeal: nothing new to learn, one more supply source in a familiar console. It also makes the channel easier to defend internally, because in-store delivery shows up in the same reports the rest of the plan lives in, instead of arriving as a separate spreadsheet someone has to reconcile.

When should you buy direct instead?

Direct is often the simpler path if you don't have DSP access, if you want hands-on help building the store list, or if this is a first test and you'd rather talk through the plan with a person than configure a platform. Nothing about direct is lesser. It's the same screens reached through a shorter pipe.

NRS Digital Media activates campaigns directly or by PMP, so the choice can follow your workflow rather than the network's preference.
