Experiment Summary
Timeframe: 03/29/2019 - 03/31/2019
We decided to see if we could promote The Heritage Guide to the Constitution offer for a premium gift with a sticky bar on the digital guide website. What we didn’t know is whether the sticky bar placement at the top or the bottom of the page would generate more traffic.
Research Question
Does the placement of a sticky bar on top or on bottom of the digital Guide website generate more clicks to the donation page / offer.

Results
Treatment Name | Click Rate | Relative Difference | Confidence | |
---|---|---|---|---|
C: | Control | 0.76% | ||
T1: | Treatment #1 | 1.6% | 108.3% | 96.9% |
This experiment has a required sample size of 1,314 in order to be valid. Since the experiment had a total sample size of 3,162, 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:
108.3% increase in traffic
× 0% increase in conversion rate
× 0% increase in average gift
Key Learnings
With a 95% level of confidence, we were able to prove that the sticky bar placed at the top of the page generated 108% more clicks than when the sticky bar was placed at the bottom of the page.
