You posted the exact same question a few days ago already. It doesn't help to clutter the forums with multiple posts about essentially the same question.
Hi,
I started using Revive Adserver 6 months ago. In this time, I worked with a lot of publishers..
Now I'm working with one publisher (I'm buying traffic both on desktop and mobile) and starting last month we have a big discrepancy between our impressions from Revive and their impressions. But this is happening only on Desktop channel of that publisher. The discrepancy for November was approx 40%, now for 1-12 December we have the same difference - 40%.
On mobile channel we have only 3-5% differences,which is okay..
They talked with DFP and said that everything is okay from them..
Also, DFP talked about a "difference in counting methodologies"..Can you tell me how Revive ad server is counting impressions?
PS: they don't count bot impressions.
It's huge this discrepancy, right? What should I do? Can you help me, please?
Thank you.
