The rise of vertical video
Each year, I try to think of the most valuable impression in our ad space. For many years, I’ve always sourced the answer to YouTube TrueView Skippable Ads. Rightfully so, since you don’t pay for a user until they watch 30 seconds of an ad (or, if the video is shorter in length, they complete or engage).
However, I’ve changed my opinion recently. I am convinced that vertical video is the most valuable impression on the web today.
