The Button Color Debate Ends Here
The argument:
Designer: "Green buttons are more modern and convert better"
Boss: "Blue feels trustworthy, we should use blue"
You: "Let's test it and let data decide"
A/B testing setup:
- Show blue button to 50% of visitors (Control)
- Show green button to 50% of visitors (Variant)
- Measure click-through rate
- Winner: Whichever gets more clicks
This is how Google, Netflix, and Amazon make billions in extra revenue—they test everything.
