Why It Worked
The persistent cart banner solved a mobile shopping problem by bridging the gap between browsing and purchasing. There were two factors behind its success:
Maintaining Purchase Momentum
The persistent cart banner kept selected items top-of-mind throughout the browsing experience, maintaining active purchase intent while allowing customers to continue shopping.
Strategic Mobile Real Estate Allocation
Despite limited mobile screen space, the addition of the cart banner proved that strategic additions can outperform minimalist approaches. The 5% revenue lift demonstrated that keeping cart contents visible was worth the screen space investment.
