I see a big difference between the number of displays I’ve served and impressions registered in my dashboard. Why is this?

 

Your placements are not getting a viewable impression.

 

Anzu respects both developers and advertisers and only charges for viewable impressions. Ad viewability is defined as at least 50% of an ad in view for a minimum of one second for display ads or two seconds for video ads.

 

 

You should optimize the placement by enlarging it, changing the size, and even adding video. Alternatively, you can remove game objects covering the ad.

 

You may wish to contact your Anzu account manager, who can support you with this.
