Buckner International was promoting a new guide on how to talk to your kids about poverty. The goal of the campaign was to serve as an email acquisition mechanism to grow their house file. They had created a promotional video to be used in advertising but we wanted to test this new medium against the standard control which was an image of the offer.
They wanted to see whether including the video instead of an image would increase people’s motivation to download the offer.

This experiment has a required sample size of 13,768 in order to be valid. Since the experiment had a total sample size of 30,976, and the level of confidence is not above 95% and the statistical power is above 80%, the experiment results are not valid.
The video ad saw an increased conversion rate of nearly 60%. We did not yet reach statistical validity but at a 94% level of confidence, it was quickly approaching this. It is our hypothesis that this is likely because the video lined up more with the ad content and the storyline, creating an emotional connection with the topic that the offer was covering. This increased people’s motivation to download the offer.
