How the right value proposition can affect conversion
Experiment ID: #1780
Dallas Theological Seminary
Experiment Summary
Timeframe: 07/29/2015 - 08/05/2015
Dallas Theological Seminary wanted to increase donor conversion rate on their main donation page. Two previous tests had failed to do so by adding value proposition language and changing the open gift field to pre-selected buttons.
The question was raised — what if the first value proposition test had the right language, but the wrong presentation? DTS crafted a new version of the value proposition that started with a fundamental truth that the audience could agree with: “The world needs Biblical truth now more than ever.” This copy also included a quote from Chuck Swindoll that was inline with the text, as opposed to offset in the previous test.
Finally, DTS added a subheadline and strengthened and bolded the call-to-action.
Research Question
Will a stronger value proposition increase donor conversion rate?
