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%?
