Apple bases its campaign delivery and pacing on viewable impressions. There may be variances when comparing third-party reporting metrics because viewability standards vary among third-party vendors. Requested impressions may be more closely aligned with a third-party vendor’s standard impression metric since it is based on the initial request, and not Apple’s viewability standards. Reporting metrics include:
Requested impressions: When an initial request is made through the Apple proxy to a third-party server.
Video impressions: When 50% of the video ad is displayed and playing on-screen for at least two continuous seconds.
Viewable impressions: When 100% of the banner is fully displayed on screen for one second or more.
Attention metrics on Moat can be measured through viewable impressions delivered within Apple News. This will allow you to independently verify impressions via Moat metrics such as one second fully on-screen and invalid traffic rate.
If you have a Moat account, you can gain access by providing your org ID (located on Workbench) to your Moat representative who can assist you with access.
