A/B Test: Which Call-to-Action Button Color Increased Opt-ins 132.41%?

LeadPages Business Development Manager Brandon Lytle said something that struck a chord with me the other day.

He remarked that a call-to-action button isn’t just a little rectangle full of words. It’s “your virtual salesperson.”

That is, it’s the thing that asks your potential customers to buy or opt in. And just as you wouldn’t send your salespeople out into the field without thinking carefully about how they’re presenting themselves, you should pay close attention to how your call-to-action buttons appear.

This should make A/B testing your call to action buttons a high priority, right? We think so, and so did stock analyst Jae Jun of OldSchoolValue.com.

In this A/B test, Jae set out to find which button color would receive the most opt-ins: green or yellow.

Which version do you think increased opt-ins for this LeadBox™ by 132.41%?

If you chose Version A you are correct!

Version A, with a 100% probability of outperforming Version B, increased opt-ins by 132.41%.

Although we can’t say with total certainty why this change caused the increase, here are a few of my speculations:

  1. Yellow is commonly associated with caution, which may have subconsciously prevented some visitors from opting in.
  2. Green is traditionally associated with growth and money, and may have provided extra motivation to opt in.
  3. The progress bar in this LeadBox is also green, which might have made the LeadBox seem more cohesive and drawn attention to the fact that visitors are already “50% complete.”
