Viewability looks at the number/percentage of ads that were seen on screen compared to the total number of impressions. Buying an Ad Impression doesn’t guarantee that the Ad will be seen on screen. IAB defines an ad as “viewed” when at least 50% of the ad pixels were on screen for 1 second or more, and 2 seconds for Videos. Metrics such as viewability and interaction rates have become more relevant metrics to the goal of generating conversions. The average viewability rate for a campaign is 45%
