Programmatic guaranteed (PG): fixed-price reserved inventory via DSP

What PG actually is

A programmatic guaranteed deal is a one-to-one commitment between a buyer and a publisher: a fixed CPM, a guaranteed volume of impressions, a defined time window, on a defined inventory package. The publisher commits to delivering the volume; the buyer commits to paying for it whether or not their creative actually serves to every impression. The deal ID is added to a DSP line item, and PG impressions are delivered with the highest priority in the publisher's ad-server waterfall — above PMP, above open-exchange RTB.

PG looks like a direct buy from the publisher's revenue perspective: predictable, contractual, billed at the agreed CPM. PG looks like programmatic from the buyer's operational perspective: trafficked through the DSP, reported alongside other campaigns, optimized within the constraints of the deal.

Preferred Deal	Best effort	Fixed	First look	Medium
PMP	Best effort	Floor + bid	Invited auction	Low-medium
Open Exchange	Best effort	Bid	All eligible	Low

The CTV PG explosion

CTV upfronts now run almost entirely on PG pipes. The reason: streaming inventory has a finite supply (you can't manufacture more eyeballs on Hulu) and demand is dramatically elastic during upfront season. Publishers want certainty about which advertisers are committing to what inventory; advertisers want certainty that they'll get the inventory they need around tentpole moments. PG provides both. Connected TV advertising walks through how the CTV market evolved from upfront-only to PG-dominant.

When PG is the right call

• Tentpole inventory. NFL Sunday Ticket on YouTube, Super Bowl, awards-show streaming — guarantee the inventory or it will be sold to a competitor.
• Seasonal certainty. Holiday campaigns where guaranteed volume on premium inventory is operationally critical. PG locks the inventory in October for December delivery.
• Custom creative integrations. Branded segments, sponsored content, ad pod ownership — the creative work justifies the inventory commitment.
• High-value audiences with scarce supply. When the audience is small and the inventory is contested, PG removes the risk of being out-bid in the open auction.

What PG isn't good for

PG doesn't optimize. Once the deal is signed, the volume, CPM, and inventory are locked. If performance disappoints, you can't shift the budget to a different audience or publisher. For advertisers who measure ruthlessly on CPA and optimize daily, PG is too rigid. Run PG only where the commitment itself is the point — inventory access, custom creative, or upfront certainty.

Reconciliation

PG reconciliation is more involved than PMP reconciliation because there's a delivery commitment. If the publisher under-delivers by more than 5%, they typically owe make-goods (free impressions on equivalent inventory in a future window). If the buyer's creative fails to serve (incorrect tags, blocked domain, creative rejected), the publisher may not owe make-goods because the under-delivery is the buyer's fault. Both sides need clear logs.

How does PG differ from a preferred deal?

PG is volume-guaranteed; preferred deal is not. Both use fixed CPMs and bypass the auction. In PG, the publisher commits to delivering a specific volume; in a preferred deal, the buyer gets first-look access at the fixed price but can pass on impressions they don't want.

Can I run PG across multiple publishers?

Not as a single deal. PG is one-to-one. To assemble a multi-publisher PG, you negotiate separate PG deals with each publisher (or use a curated marketplace that wraps them into a packaged offering, though those usually transact as PMPs not PG).

What's a typical PG CPM premium over open exchange?

For CTV, 50-300% premium over open-exchange CTV CPMs. For display, 100-400%. The premium is paying for guarantee, priority, and often custom creative ownership.

Are make-goods automatic?

Usually yes if specified in the deal. If the publisher under-delivers by more than a contractual threshold (commonly 5%), they owe equivalent impressions on equivalent inventory in a future window. Get this written into the deal terms.

Does PG bypass viewability and IVT filtering?

Pre-bid filters can still apply if you configure them in the DSP, but they reduce the volume you're paying for. The PG commitment is to deliver impressions; filtering them out post-delivery is the buyer's choice. Most teams accept slightly looser filtering on PG in exchange for the inventory guarantee.

How is PG priced?

Annual upfront commitments often get tiered pricing: lower CPM for higher volume commits. Spot PG (quarterly or campaign-specific) usually carries a premium. Negotiate the rate-card with reference to the publisher's open-exchange clearing price plus the appropriate premium for guarantee.

Operating checklist

1. Define the desired outcome before opening a platform UI.
2. Validate platform fit against budget, geo, and inventory access needs.
3. Set frequency caps, viewability floors, and IVT filters at line-item launch.
4. Run a controlled holdout to measure incrementality, not last-click.
5. Review pacing, viewability, and brand-safety reports weekly.
6. Reconcile delivery against publisher-side reporting monthly.
7. Document seat IDs, deal IDs, contacts, and lessons learned in a runbook.
