CaringBridge was running a Valentine’s Day fundraising campaign and had a $25,000 matching gift. They knew that most of their donations on these short, high-urgency appeals came through a few donation funnels that landed on the same page. While previous tests had focused on driving traffic, they wanted to see if they could optimize conversion by driving home the match language on the two days that the gift was applied. They created two versions of a sticky top banner for the donation page—one that emphasized the match for “your” gift, and another that emphasized the match for “all donations”. They launched a three-way experiment split between mobile and desktop to see how it affected conversions on desktop devices.
How will visual reinforcement affect donor conversion on the donation page during a short-term matching gift appeal?
|Treatment Name||Conv. Rate||Relative Difference||Confidence|
|T1:||Header (Personal Message)||32.8%||24.4%||98.5%|
|T2:||Header (All Donations)||27.5%||4.2%||34.2%|
This experiment has a required sample size of 569 in order to be valid. Since the experiment had a total sample size of 1,832, and the level of confidence is above 95% the experiment results are valid.
Flux Metrics Affected
The Flux Metrics analyze the three primary metrics that affect revenue (traffic, conversion rate, and average gift). This experiment produced the following results:
0% increase in traffic
× 24.4% increase in conversion rate
× 0% increase in average gift
The simple banner improved conversion by 24%. What’s interesting is that the language on the conversion pathway all mentioned the match as well—but none of the language on the page did. By reinforcing the match—which some people were just seeing for the first time—they were able to have a significant impact on conversion.
It’s worth noting the significant (though not statistically valid) difference between the “personal” language and the “all donations” language. When your language speaks directly to the person on the site, rather than including them in a large, impersonal group, conversion is increased.
