Video Ads on the Microsoft Audience Network

Adding video to your search campaigns on the Microsoft Audience Network can increase conversions by 50% compared to running a search campaign without video. Video ads are targeted using intent data from Bing search, the Microsoft Edge Browser, LinkedIn, and users’ web activity. - Optimize for video completion: Bid per view. A view is counted when a viewer watches your ad to completion or for at least 30 seconds, whichever comes first Microsoft offers two bidding options for video ads: impression-based or view-based. An impression is counted when a viewer watches two seconds of continuous play. A view is counted when a viewer watches your ad to completion or for at least 30 seconds, whichever comes first. Microsoft Advertising will automatically generate multiple videos for each aspect ratio (16: 9, 5: 4, 1: 1, 4: 5, and 9:16), or you can upload your own videos in each available aspect ratio.
