What is Programmatic Guaranteed (PG)?
Programmatic Guaranteed, often shortened to PG, is a buying model where an advertiser and a publisher agree on a fixed price, fixed volume and fixed flight, and execute the deal through a programmatic pipe. The inventory is reserved up front, but the trade itself runs through the same DSP and SSP plumbing as open auctions.
PG sits between traditional insertion order trading and open RTB. It gives both sides the predictability of a direct deal while keeping the operational efficiency of programmatic delivery, including unified reporting, frequency capping and creative trafficking.
How it works
The buyer and seller negotiate a deal ID with agreed CPM, impression volume and date range. The publisher reserves the impressions and prioritizes them above open auction demand. Inside the DSP, the buyer sets up a campaign tied to the deal ID, applies its own targeting and creatives, and tracks delivery in the same dashboard as the rest of its programmatic spend.
PG deals run on most major ad servers and SSPs, including Google Ad Manager, Magnite, FreeWheel and PubMatic. Pricing is usually higher than open exchange CPMs because the buyer is paying for guaranteed delivery and premium placement, often on top tier publishers or premium CTV inventory.
Why it matters
PG gives brand advertisers access to high quality inventory with the certainty they need for product launches, brand campaigns and tentpole moments. For publishers, it locks in revenue from priority advertisers without giving up programmatic operational efficiency.
For performance focused buyers, PG is useful when reach quality matters more than CPM efficiency. CTV launches, premium publisher takeovers and seasonal pushes are the common use cases. Affiliates and DTC brands typically lean on PMP and open auction, but mature performance accounts add PG selectively for top funnel.
