Viewability

Viewability is an assessment of the quality of ad creative display (banner, native, or video): whether it was actually rendered and seen by the user, how long it stayed in the visible zone, and how the user watched the video. Technically, Viewability runs inside the same script as antifraud: the user is checked for fraud first, then the fact and quality of the creative impression are recorded. Below are all Viewability metrics, grouped into three categories: display quality (Viewability), engagement (Attention), and viewing depth (Video consumption). Most metrics are counted per impression; rate metrics are calculated in aggregate and shown as percentages (0–100%).
