I have been doing this experiment with ads on video and ads on regular website.
So below are the 2 best performing ads from today and top one is video ad which was placed on video and the ad on 2nd is on regular content site. As you can see even with 4k impressions compared to 15k on regular ad, video ad earned double the amount of money. The RPM is 5 times more as well.
So If any of you guys here have a video website I recommend to place ads on your video.
