What is Deal ID?
Also called: deal ID, dealid
A deal ID is the code that ties a programmatic bid to an agreed deal, so the SSP, DSP and ad server all apply the deal's terms.
हिंदी में पढ़ेंWhen you set up a deal in your SSP, it gets a deal ID. The buyer adds the same ID to a DSP campaign. When a matching impression comes up, the SSP puts the deal in the OpenRTB bid request, inside the pmp object, with the ID, a floor and the allowed buyer seats.
The DSP bids and copies the ID into the dealid field of its bid. With Prebid, the ID reaches Google Ad Manager as a key-value in the format hb_deal_BIDDERCODE, and a deal line item, set at a higher priority than the open-market Prebid line items, picks it up.
The ID must match exactly at every step. If the buyer types it wrong, its bids still arrive, but they look like open auction bids, and the deal underdelivers. That is why checking the ID in the SSP, the DSP and the ad server is one of the first troubleshooting steps for a quiet deal.
Example
A deal is created as NEWS042 with a $6.00 floor. The buyer types NEWS024 in its DSP. Its $6.50 bids reach the auction as ordinary open market bids, and the deal records 0 impressions.
Why it matters to publishers
A mismatched deal ID is a simple cause of deals that never deliver, and one of the quickest to check.
