Made your call? See the result
The family photo with “Learn More” beat all 24 combinations.
What happened
The team tested 4 buttons and 6 media (3 images, 3 videos) as a full factorial test, about 13,000 visitors per combination. The staff favorite, a video, did not win.
Why it worked
“Learn More” asks for less commitment than “Sign Up”. A warm photo reads at a glance and needs no play button.
The takeaway
Your team's favorite is a hypothesis. Lower the commitment of the first click.
