The Conversion Wizards, a conversion rate optimization (CRO) consultancy, was entrusted with boosting the conversion rates of a multibillion dollar company.

We used research to optimize the page and ran an A/B test. The winning version, labeled “radical,” resulted in a 75% increase in sales.

We took the average of those two identical pages as the baseline to determine the lift, and it revealed a 75% increase at 99% statistical significance.

Here are the Google optimize screenshots:

Before I discuss the changes that produced the lift, it is important that I quickly go over the research that informed those changes. Why? Because it is a critical aspect of the process and too many CRO practitioners do not devote enough attention to figuring out why more site visitors aren’t converting.
