How the impact of an ad’s image affects click through rate
Experiment ID: #11668
National Breast Cancer Foundation
Experiment Summary
Timeframe: 07/03/2014 - 08/09/2014
As part of the promotion of their free eBook, Teen Mania was running Facebook ads in order to acquire new prospect emails. We wanted to find out what factors of the book were most appealing to the audience so we ran an experiment on the imagery used in the ad. Since the author of the free book is well known, we tested to see if his image would drive more interest than highlighting the book itself.
Research Question
What drives more clicks — a picture of the offer, or a picture of the author?
