How to Evaluate Pharma PMPs Before Committing Budget

A deal evidence card and pre and post-launch validation checklist for private marketplace deals in pharma programmatic.

The short answer

Private marketplace deals promise access to specific inventory, often at a premium price, with more control than the open exchange. In pharma, PMPs are common for endemic health publishers and curated HCP or DTC packages. But a deal ID is only a label. What matters is what actually delivers through it. Many PMPs deliver differently from how they were described.

Build a deal evidence card

Before committing budget, ask the seller to fill in a short card.

Field What to ask
Inventory Which domains or apps are included? Is the list fixed or does it change?
Formats Which sizes and video lengths?
Audience Is audience data applied? From what source?
Floor price What is the floor, and does it change?
Volume Expected available impressions per week at your targeting
Exclusivity Is this inventory also available elsewhere, including open exchange?
Supply path Which exchange, and is the seller listed in sellers.json?
Quality Verification results from recent campaigns

Validate before launch

  1. Check the domain list against ads.txt authorization. See ads.txt, sellers.json, and schain.
  2. Compare against open-market access. If the same inventory is available on the open exchange for less, the deal needs another justification.
  3. Confirm the deal is set up correctly in your DSP, with the right targeting applied on top.

Validate after launch

Within the first two weeks:

  • Compare delivered domains and apps to the promised list.
  • Check viewability, invalid traffic, and context against expectations.
  • Check volume against the seller's estimate.
  • Compare the effective price, including fees, with alternatives.

Deals that deliver mostly outside their promised inventory, or at much lower volume, should be renegotiated or paused.

When PMPs are worth it

PMPs make sense when they provide:

  • Access to inventory not available otherwise.
  • Better quality, verified by your own data.
  • Audience data applied by the publisher that you cannot replicate.
  • Operational simplicity that outweighs the premium.

They are harder to justify when they repackage open-market inventory at a higher price.

Compare transaction types

PMPs are one of several ways to buy. See direct, PMP, or open auction for how to choose among them.

Practical takeaway

Require a completed deal evidence card before activating any new PMP. Review delivered inventory against it in week two, and keep or cut the deal based on what delivered.
