0% increase in traffic
× 20.8% increase in conversion rate
× 0% increase in average gift
Key Learnings
The image of “Satan” not only increased clicks and names acquired, but it increased donor conversion as ell by 21%. This was an interesting experiment because what we’ve known from other testing is that an image of the eBook communicating what a person would get usually increases conversion. But with the nature and topic of this offer, the image of “Satan” increased the appeal of the offer by reinforcing the topic and purpose for the offer. It created intrigue and increased the feeling in people that they probably needed what this eBook had to offer as a solution based on the image that depicts the problem.
