What is Ad Viewability?
Ad viewability is a metric used in digital advertising to measure how visible the ads are on the publisher’s website to users. According to the Interactive Advertising Bureau’s (IAB) standard, for an ad to count as ‘viewed’, 50% of it must be visible to a user for at least 1 second. For video ads, 50% of the ad must be visible for at least 2 seconds. Google refers to viewable impressions as ‘Active View‘.
