In this episode of Conversion Rate Optimization with Fexingo, hosts Lucas and Luna dive into a specific CRO tactic that often gets overlooked: the scroll-triggered sticky bar. They break down a real case where an e-commerce site selling premium dog beds used a simple, non-intrusive bar that appeared only after a user scrolled past the hero section. The bar offered a 10% discount code in exchange for an email, and it lifted overall conversion by 16% without hurting the user experience. Lucas explains the psychology behind the placement — letting users engage with the product first before presenting an offer — and why the team tested for cannibalization against a control. Luna challenges the assumption that sticky bars are always annoying, and they discuss key testing variables like scroll depth, copy length, and mobile responsiveness. They also cover how the team measured secondary metrics like bounce rate and time on page to ensure the bar wasn't driving people away. If you're looking for a low-risk, high-impact test that respects user intent, this episode gives you a concrete framework to try.
