A/B Test: One Word, Two Spellings: Which One Increased Opt-ins 25.87%?

We’ve seen A/B tests that show what a huge difference even two words on a page can make—but what about two letters? Milan Jara of Decorative Ceiling Tiles got some surprising answers to that question in this recent A/B test.

Milan’s LeadBox™ asks visitors to opt in to receive the latest catalog. Or catalogue. Either spelling is valid, so Milan decided to let an A/B test decide which one he’d use in the call-to-action button.

Which version do you think increased this LeadBox’s opt-ins by 25.87%?

If you chose Version A you are correct!

Version A, with a 99.04% probability of outperforming Version B, increased opt-ins by 25.87%.
Although we can’t say with 100% certainty why this change caused the increase, here are a few of my speculations:

  • Version A’s spelling of the word “catalogue” matches the headline, providing continuity between the headline and call-to-action button within the LeadBox®.
  • Catalogue is both a more old-fashioned spelling and the French spelling of the word. That might resonate better with customers interested in the old-world design of Milan’s products.

When it comes to your call-to-action copy, you should usually aim for consistency among the elements of your LeadPages® and LeadBoxes™. Using consistent spelling helps prevent confusion between your pages and your visitors. Using language that evokes the feel of your product or service can also have a big impact on your opt-in rate, as it contributes to the overall visitor experience.

Not all visitors are the same, but A/B testing your call-to-action copy may be something to consider for your own LeadBoxes™.
