How length of copy affects conversion rate in a Facebook ad
Experiment ID: #6757
The Missionary Oblates of Mary Immaculate
Experiment Summary
Timeframe: 05/18/2017 - 06/07/2017
The Missionary Oblates were running a campaign promoting their new email acquisition offer, a Daily Prayer via email. They wanted to test whether a more in-depth value proposition in the ad copy converted more people than shorter, more concise ad copy. All other elements of the ad remained the same.
Research Question
Does longer, more in-depth copy about an offer in a Facebook ad increase conversion rate?
Design
C: Short Copy
