Facebook recently introduced "Auto Play" videos feature in News Feed last month, now has come up with a new direction for ads. That is "Video Ads" which will be available in Facebook Apps on Android and iOS devices.
Videos will be coming to mobile apps in ad products. It will give you ti install ads option, making the advertisers to make more money based on CPA (Cost Per Action).
According to Radu Margarint (Facebook's Software Engineer), "Video creative has proven to be an effective way to drive engagement in news feed, and we look forward to helping developers use their video creative to find new app installs".
Previously these ads were displayed only in text and images format, now the advertisers will get a fairer chance to display video ads. These video ads will not automatically play in the mobile app news feed, the user has to tap on it to play.
