DOOH multiplier measurement source types
This list says who measured the impression multiplier on an out-of-home opportunity: a measurement vendor, the publisher, or the exchange. OpenRTB 2.6 sends it in Qty.sourcetype, under imp.qty, next to Qty.multiplier, the number of impressions one play is worth. Buyers use it to decide how much to trust the multiplier they are paying for.
Values
| Value | Name | What it means |
|---|---|---|
0 | Unknown | The source of the multiplier is not known. |
1 | Measurement Vendor Provided | An independent audience measurement vendor supplied the multiplier; name it in Qty.vendor. |
2 | Publisher Provided | The publisher or screen owner supplied the multiplier. |
3 | Exchange Provided | The exchange calculated or supplied the multiplier. |
Fields that use this list
How to use it
A DOOH screen in a busy location is seen by many people at once, so one ad play can be sold as several impressions, for example 8.5. Qty.multiplier holds that number and Qty.sourcetype says where it came from. When the source is a measurement vendor (1), name the vendor's business domain in Qty.vendor. The specification recommends sourcetype whenever Qty is present.
Common mistakes
- Sending 1 without
Qty.vendor. The specification requires the vendor's domain in that case. - Leaving
sourcetypeout, which leaves buyers no better informed than 0. - Sending 1 when the publisher derived the number itself from older vendor research. Buyers expect 1 to mean the vendor supplied the figure for this placement.
Validation
On OpenRTB 2.6 snapshots, RTBlint reports a value outside this list as openrtb.value.invalid. Paste a request into the tester to check the values you send.
