According to a recent study led by VidMob, video ads drive a 48% higher sales rate than static ads. But the most striking findings indicate that the length of video ads is a key consideration to optimize a campaign success. The study revealed that 10 to 15 seconds spots have a 19% higher purchasing rate than average. Additionally, ads that showed text within the first three seconds boosted online purchases by 46% more than ads who didn’t didn’t show any text. Essentially, the study signaled that shorter ads are less convincing when it comes to driving online sales. This finding may point out the critical importance of storytelling for brands.
