How a Facebook headline affects direct-ask donor conversion
Experiment ID: #8071
The Heritage Foundation
Experiment Summary
Timeframe: 10/24/2017 - 12/12/2017
The Heritage Foundation noticed an opportunity on Facebook to retarget visitors who viewed their online donation pages. They created to direct ask Facebook ads that invited anyone who visited the page but did not complete the form to return and support the Heritage Foundation. In the first ad, they simply asked all visitors (including members who visited the page) to ‘Donate now.’ In the second ad, the asked all non-member visitors to join the Heritage Foundation by ‘Becoming a member today.’ They launched a test to find out which approach would be more effective at converting donors.
Research Question
Will the headline ‘Donate now’ or ‘Become a member’ drive more donor conversions on a Facebook ad?
