Viewability
Viewability in digital advertising refers to the metric that measures whether an ad is visible to a user on their screen.
For an ad to be considered viewable, industry standards typically require at least 50% of the ad’s pixels to be in view for a minimum duration, such as 1 second for display ads or 2 seconds for video ads. It helps advertisers ensure their ads are seen and not wasted on impressions that go unnoticed.
