Different impression counting methodologies between Prebid Universal Creative and GAM via Prebid Mobile SDK #206

Closed hmodes-qm closed 3 months ago

hmodes-qm commented 1 year ago

Hi,

we're running Prebid Mobile SDK in native apps and have noticed that there are discrepancies in the way Prebid and GAM track impressions.

GAM refers to this:

"Google Ad Manager counts mobile app impressions in alignment with industry standards using the “Begin to render” counting methodology. Mobile app impressions are counted when one or more pixels of the ad creative is visible on a device's screen." However SSPs that run through the Prebid SDK track impressions when their code is served instead of when at least 1px of the ad is visible on the device's screen.

Is there already a way to match the methodologies by events, impression callbacks or anything like that?

Thanks in advance!

@hmodes-qm - first, the PUC doesn't promise to count impressions - it is capable of counting BIDS_WON. Those are different.

If you still have a Prebid SDK tracking question, please open in https://github.com/prebid/prebid-mobile-ios/issues
