Experiment ID: #1947

Experiment Summary

Timeframe: 08/16/2015 - 08/31/2015

In a previous experiment, we had validated the messaging approach to use for a money bomb campaign. Because it involved a physical building, we felt this campaign would lend itself better to images to help convey the message. This is a different approach than we normally take with money bombs so we wanted to be sure to validate the impact these images had on the overall campaign performance

Research Question

Does the use of imagery help boost donor conversion on the page?

Design

C: Images
T1: No Images

Results

  Treatment Name Conv. Rate Relative Difference Confidence Average Gift
C: Images 19.7% $88.24
T1: No Images 19.0% -3.9% 55.1% $77.93

This experiment has a required sample size of 19,902 in order to be valid. Unfortunately, the required sample size was not met and a level of confidence above 95% was not met so the experiment results are not valid.

Key Learnings

The addition of the images to the page created no significant lift to either donor conversion or average gift. They made the page more visually appealing but this didn’t impact the donors’ likelihood to give a gift.
