Video
A Video Ad that meets the criteria of 50% of the ad’s pixels on an in-focus browser tab in the viewable space of the browser page can be counted as a Viewable Video Ad Impression if it meets the following time criterion:
- Video Time Requirement: To qualify for counting as a viewable video ad impression, it is required that 2 continuous seconds of the video advertisement is played, meeting the same Pixel Requirement necessary for a viewable display ad. This required time is not necessarily the first 2 seconds of the video ad; any unduplicated content of the ad comprising 2 continuous seconds qualifies in this regard. View More
