300% Conversion Increase for E-commerce Client

The Challenge

Our e-commerce client faced a critical problem: despite investing in digital advertising, conversions remained stagnant at 0.8%. Initial analysis revealed that 68% of visitors abandoned the site before completing a purchase.

The main barriers identified:

• Excessive load time (5.2 seconds average)
• Fragmented and difficult-to-navigate mobile experience
• Checkout process with 7 unnecessary steps
• Unoptimized product images (2-4 MB PNG files)

The Solution

We implemented a comprehensive redesign strategy focused on performance and user experience:

Technical Optimization

• Migration to Astro 5 SSG to eliminate unnecessary JavaScript
• Conversion of all images to AVIF format with WebP fallback
• Implementation of lazy loading and web font optimization
• Reduced JavaScript bundle from 847 KB to 89 KB

UX Improvements

• Redesigned checkout process from 7 to 3 steps
• Implemented category navigation with dynamic filters
• Mobile-first design with responsive components
• Design system with semantic tokens for visual consistency
