Initial Situation — Audit and Diagnosis

At the start of our engagement, we conducted a comprehensive UX audit of the existing online store. The analysis covered both visual and technical layers — from information architecture to page load performance across devices. The findings were unambiguous: the store required fundamental modernization.

The audit revealed several critical issues. The product page on mobile devices took a full 7 seconds to load. CTA buttons were too small for touchscreens, and the purchase path comprised 6 steps — far too many to retain mobile users' attention. Mobile bounce rate stood at 78%, dramatically below industry benchmarks.

Google Analytics data confirmed that over 62% of traffic originated from mobile devices, yet mobile conversion was a mere 0.3% compared to 2.1% on desktop. This sevenfold gap clearly indicated where the problem lay — and where the greatest growth potential was hiding.

Mobile-First Design Methodology

We adopted a mobile-first approach, meaning we designed from the smallest screen upward. We began by analyzing mobile user behavior — heatmaps, session recordings, and conversion paths provided valuable data on how PRIMAMODA customers actually navigated the store.

We designed a new information architecture based on a simplified navigation tree. Product categories were reorganized according to most frequently searched terms and most popular purchase paths. The hamburger menu was replaced with intuitive icon-based navigation with quick access to key categories.

Performance Optimization and Core Web Vitals

One of the project's key elements was technical optimization for Core Web Vitals — Google's metrics that determine search rankings and user experience quality. Before our intervention, the store recorded critically low scores across all three indicators.

Largest Contentful Paint (LCP) dropped from 7.2s to 1.8s through server optimization, CDN implementation, and image compression to WebP format. First Input Delay (FID) improved from 340ms to 45ms after thorough JavaScript refactoring. Cumulative Layout Shift (CLS) decreased from 0.42 to 0.05 through image placeholders and space reservation for dynamically loaded elements.

JavaScript Optimization Techniques

The JavaScript layer required a fundamental rebuild. Bundle analysis revealed that the main JS file weighed over 1.2 MB, with nearly 60% being unused code. We implemented a code splitting strategy — dividing code into smaller modules loaded on demand.

• Tree shaking — removing unused code from the production bundle
• Dynamic imports — lazy loading components below the fold
• Debouncing and throttling — optimizing scroll and resize event listeners
• Service Worker — caching static resources for faster repeat loads
• Minification and Brotli compression — 73% transfer size reduction

After optimization, the main JavaScript bundle shrank to 320 KB (73% reduction), and Time to Interactive on mobile dropped from 9.4s to 2.8s. This directly translated to lower bounce rates and higher user engagement.

Black Week Campaign Strategy

We strategically timed the new store version launch for one week before Black Week — e-commerce's most critical sales period. This gave customers time to familiarize themselves with the new interface before peak shopping.

Lessons Learned and Recommendations

The PRIMAMODA project confirmed several key principles of digital transformation in e-commerce. First, mobile-first isn't a trend — it's the standard that should be the foundation of every e-commerce project. Second, technical optimization and UX design must go hand in hand — a beautiful site that takes 7 seconds to load doesn't sell.

Third, data should drive every design decision. Heatmaps, session recordings, and A/B tests enabled us to make decisions based on actual user behavior rather than assumptions. Finally, the tight timeline paradoxically helped with prioritization — forced to choose, we focused on changes with the greatest conversion impact.
