Dark Viewability

Impressions that are unable to be tracked for viewability. If an ad is displayed within a nested iFrame (“cross-domain iFrames”), its position on the page cannot be determined. Viewability vendors use different workarounds for this challenge, often with varying degrees of success, resulting in a certain percentage of “unmeasurable” impressions in a viewability report.
