Executive Summary
Premium furniture retailer struggled with mobile cart abandonment despite rising traffic. Our persistent shopping cart banner test across 1.7M users increased conversion rates by 5.9% and drove a 5% revenue lift, with 98% statistical confidence.

Highlights

We implemented a persistent shopping cart banner across their mobile site, keeping selected items visible throughout the customer journey.

Key Achievements:

  • Revenue per user increased by 5%, driving significant bottom-line impact
  • Conversion rate improved from 0.17% to 0.18% (5.9% lift)
  • Cart visibility improved purchase completion with 98% statistical confidence

The Challenge 💡

Mobile traffic was increasing rapidly, but the conversion wasn't keeping up. Users were adding products to cart but failing to complete purchases.

Our Solution ⚡

We proposed adding a persistent shopping cart banner that would remain visible throughout the customer journey.

Cart Banner Features:

  • Persistent display of current cart contents
  • Clear "Checkout Now" CTA
  • Present across all pages except cart

Technical Implementation ⚡

Test Parameters:

  • Device targeting: Mobile only
  • Browser coverage: All major mobile browsers
  • Even split A/B test

Control: Mobile homepage showing primary navigation and the simple Recently Viewed banner.

Variation 2: Shopping cart banner implementation showing '3 Items in Shopping Cart [ Checkout Now ]' at top of page in red, followed by Recently Viewed section. Demonstrates how cart contents remain visible while browsing.

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:

  1. 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.
  2. 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.
