PMP vs. Programmatic Guaranteed: What Is the Difference?
A private marketplace (PMP) is an invitation-only programmatic auction, while a programmatic guaranteed deal reserves a fixed volume of inventory at a fixed price without an auction.
How does a PMP work?
A PMP is an invitation-only real-time auction in which a publisher offers specific inventory to a named set of buyers under pre-negotiated terms, controlled by a deal ID and usually carrying a price floor. Buyers still compete for each impression, so a PMP guarantees the terms of participation but not the volume delivered.
How does programmatic guaranteed work?
Programmatic guaranteed removes the auction entirely. A single buyer and publisher commit in advance to a fixed number of impressions at a fixed price, then execute that reservation automatically through programmatic pipes. It offers delivery certainty in exchange for giving up auction-driven cost savings.
When should an advertiser use each?
PMPs suit always-on buying where efficiency and flexibility matter and exact volume is not critical. Programmatic guaranteed suits moments that demand certainty — product launches, premieres, and tentpole events — where an advertiser needs guaranteed presence on specific dates.
Aurum Networks combines the two, sustaining reach through curated PMPs and reserving volume through programmatic guaranteed deals around the moments that matter, all on disclosed pricing.
Frequently asked questions
- Does a PMP guarantee delivery?
- No. A PMP guarantees negotiated terms and access, but delivery still depends on winning each impression in the auction. Only a guaranteed deal reserves fixed volume.
- Is programmatic guaranteed the same as a traditional insertion order?
- It achieves the same volume and price certainty but executes automatically through programmatic infrastructure, adding programmatic targeting and reporting.
