A/B Test: What Kind of Guarantee Boosted the Opt-in Rate 48.32%?

Advertising a money-back guarantee can definitely convince hesitant customers to open their wallets. It makes intuitive sense, but there’s also some data behind this. For instance, a 2011 study in the Journal of Retailing found that money-back guarantees “evoke a positive emotional response, thereby increasing consumers’ purchase intentions and willingness to pay a price premium.”

But can you increase your revenue simply by changing the way you present that guarantee?

And beyond that: can you drive additional engagement even before the purchase stage by mentioning the guarantee?

Almost certainly. In today’s featured A/B test, one LeadBox™ for a coupon outperformed the other by 48.32% when it framed its money-back guarantee differently.

Version A invited customers to “Put it to the test risk free. You have nothing to lose but your competition.” Version B was more straightforward: “Guaranteed to improve performance or your money back.”

Which LeadBox™ do you think increased the opt-in rate by a relative 48.32%?

Note one complicating factor before you guess: the headline color also changed between variations (red in Version A, blue in Version B), so consider whether this could have an impact, too.
