How reducing form friction on email acquisition affects donor conversion
Experiment ID: #1651
Hillsdale College
Experiment Summary
Timeframe: 06/08/2015 - 07/07/2015
Hillsdale College’s Constitution 101 course is one of the biggest source of new emails and new donors for the college. Previous experiments had been able to increase the conversion rate of the donation page and had increased the number of visitors to the page. However, we had been unable to build upon the success of the initial treatment created for the name acquisition page.
We decided to create another treatment that would divide the existing form into two steps; name and email would be first, followed by the participant’s address. When we devised this experiment, we made sure to set up tracking across every step of the process to ensure any improvements in one area didn’t adversely impact the other important metrics.
Research Question
Does dividing the registration form in to multiple steps increase the overall acquisition of emails, addresses, and donors?

Results
| Treatment Name | Conv. Rate | Relative Difference | Confidence | |
|---|---|---|---|---|
| C: | Single Step Email Acquisition Form | 0.61% | ||
| T1: | Two Step Email Acquisition Form | 1.2% | 93.7% | 93.0% |
This experiment has a required sample size of 2,076 in order to be valid. Since the experiment had a total sample size of 3,570, and the level of confidence is not above 95% the experiment results are not valid.
Key Learnings
The two step form successfully increased every metric along the registration process. Email acquisition increased by 17.6% and the number of home addresses acquired increased by 9.0%. The biggest lift was achieved with the final step of the process with a 93.4% increase in donor conversion.
By spreading out the steps, we reduced the amount of mental friction associated with each step of the process. The forms looked shorter and, as such, increased the ultimate conversion along each step.
