How a visitor-focused headline affects conversion
Experiment ID: #899
Harvest Ministries
Experiment Summary
Timeframe: 03/03/2015 - 03/16/2015
Headlines are one of the most critical elements of landing pages. They are the first thing most visitors see and their job is to put the entire offer into context for the reader. Each word carries a measure of influence on the readers ultimate decision.
Hillsdale was launching a free online class to acquire more emails addresses for their file. We wanted to test language that had historically been used internally at the college when talking about classes (“enroll”) versus one that, in our minds, carried less friction (“activate”).
Research Question
What language inspires more people to sign up?

Results
| Treatment Name | Conv. Rate | Relative Difference | Confidence | |
|---|---|---|---|---|
| C: | "Enroll" sub-headline | 26.5% | ||
| T1: | "Activate" sub-headline | 34.9% | 31.5% | 99.9% |
This experiment has a required sample size of 235 in order to be valid. Since the experiment had a total sample size of 1,235, 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
× 31.5% increase in conversion rate
× 0% increase in average gift
Key Learnings
Changing just one word in the sub-headline of the page led to a 31.5% increase in the number of emails acquired. The word “enroll” carried a high amount of cognitive friction since it is often associated with both the time and effort of enrolling in something. Alternatively, “activate” is a quick action which carried far less friction.
