PMP vs Programmatic Guaranteed
Praevis supports two deal types. Choose based on whether you need guaranteed volume or flexible competition.
Private Marketplace (PMP)
A PMP deal gives selected buyers priority access to inventory at a negotiated floor price, but does not guarantee volume.
| Aspect | PMP |
|---|---|
| Pricing | Floor-based (buyers bid above the floor) |
| Auction | Second-price or first-price among invited buyers |
| Volume | Not guaranteed — buyers compete, best bid wins |
| Buyers | One or more DSPs invited to participate |
| Use case | Premium inventory access at a minimum price |
How it works: When a bid request matches the deal’s publisher and targeting, the deal ID is sent to invited buyers. They bid above the floor. Highest bid wins. If no buyer bids, the impression falls to open auction.
Programmatic Guaranteed (PG)
A PG deal locks in a fixed price and guaranteed impression volume between one buyer and one publisher.
| Aspect | PG |
|---|---|
| Pricing | Fixed CPM (no auction) |
| Auction | No auction — deal price is the clearing price |
| Volume | Guaranteed impressions over the deal period |
| Buyers | Single DSP buyer |
| Use case | Guaranteed reach for brand campaigns |
How it works: PG deals get highest priority in the auction waterfall. When a bid request matches, the PG buyer gets first right of refusal at the fixed price. If the buyer passes, the impression goes to PMP deals, then open auction.
