Home landing: CTA Button Optimization
Hypothesis
If we test a similar change on our home landing pages as rejected, we should be cautious
Test Results
Key Learning
Problem: The primary call-to-action on the home landing isn't converting at its potential — design, copy, or placement may be the bottleneck.
What was tried: rejected this UI change (Nov 4, 2019). Rejection suggests the change underperformed the control
Why it failed: Not every CTA change improves conversion. Users may have preferred the original because it was clearer, more familiar, or better positioned.
How to Apply This to Your Site
This test showed that home landing: cta button optimization hurt conversions. The change was tested on a landing page page in the saas industry. Avoid replicating this exact approach — instead, consider testing the opposite direction or a more subtle variation.
Before you test: Consider that cta tests typically require adequate traffic to reach statistical significance. Run your test for at least 2 full business cycles to account for weekly traffic patterns.
What Was Tested
Sooner or later design properties should reach optimums for their given contexts. That is, UI elements will become just right - not too big and not too small, or not too high and not to low, etc. In this leak, it seems that has approached such an optimum when they tested various button sizes on their landing page. Given that form elements and buttons should generally be bigger, it was inevitable for this new evidence to appear as an example of a button being simply too big - as seen in this beautiful experiment. :)
