A mid-sized fashion retailer reduced their cart abandonment rate from 74% to 55% over six months. This case study details exactly what they changed, in what order, and the measured impact of each improvement.

The Starting Point

Store Profile

Business type: Fashion and accessories

Monthly revenue: $180,000

• Mobile conversion significantly lagging desktop
• High ad spend with mediocre ROAS

Estimated lost revenue: At 74% abandonment with $78 AOV, approximately $110,000/month in abandoned cart value.

Diagnosis Process

Step 1: Funnel analysis Mapped entire purchase funnel with drop-off at each stage.

Step 2: Session recordings Reviewed 200 session recordings of cart abandoners.

Step 3: Customer surveys Surveyed recent abandoners with exit survey and follow-up email.

Step 4: Competitor analysis Benchmarked checkout against top competitors.

Identified Issues

Issue 1: Shipping Cost Surprise

Finding: 52% of surveyed abandoners cited shipping cost as a factor.

Data: Free shipping threshold was $100. Average cart was $78. Most customers saw $8-12 shipping cost at checkout.

Session recording insight: Customers frequently left checkout page immediately after shipping calculation.

Issue 2: Account Creation Friction

Finding: Guest checkout existed but was buried below account creation.

Data: 68% of checkouts were from new customers. Account creation was prominent, guest checkout was a small link.

Session recording insight: Customers scrolled, clicked around, then left when they could not find easy checkout path.

Issue 3: Mobile Checkout Problems

Finding: Mobile conversion was 1.8% vs 4.2% on desktop.

Data: Mobile was 62% of traffic but only 38% of revenue.

Session recording insight: Checkout form was difficult on mobile. No express checkout. Slow page load.

Issue 4: Trust Signals Missing

Finding: New customers showed hesitation at payment.

Data: First-time buyer conversion was 1.9% vs 4.8% for returning customers.

Session recording insight: Customers looked for security indicators before entering payment.

Issue 5: Cart Page Friction

Finding: Customers were leaving from cart page before checkout.

Data: Only 45% of cart additions proceeded to checkout.

Session recording insight: No urgency, no reassurance, no motivation to proceed.
