How a Single Font Change Lifted Conversion by 12 Percent

In this episode of Conversion Rate Optimization with Fexingo, Lucas and Luna explore a case study that often gets overlooked: how a small e-commerce brand improved its checkout conversion rate by 12% simply by changing its font. They break down the psychology behind typeface readability, the specific A/B test design (including sample size and duration), and why the brand's original font—a stylish but hard-to-read serif—was costing them sales. The discussion also covers how the test was structured to avoid common pitfalls like peeking and insufficient sample sizes, and why the results held up over a full two-week run. Finally, they touch on how font choice interacts with other design elements like button color and spacing, offering practical takeaways for any marketer running CRO tests.
