Challenges & Goals

Monolithic Theme Limitations

Slow release cycles for content updates

Limited flexibility to tailor experiences per channel

Performance Bottlenecks

Initial LCP (Largest Contentful Paint): ~3.5 s

High mobile bounce rate (> 65%)

CRO Opportunity

Sub-optimal mobile UX

Inconsistent storytelling and CTAs

Business Objectives

Reduce page load times by ≥ 50%

Increase mobile conversion rate by ≥ 30%

Empower marketing to publish promotions in minutes

Solution Architecture

Layer Technology / Technique

Presentation Next.js (SSR & ISR)

Content Pack Digital headless CMS (GraphQL)

Commerce Shopify Storefront API

Design System Tailwind CSS, responsive, mobile-first components

CRO Toolkit Optimizely A/B testing; Hotjar heatmaps & session replay

Headless Migration

Replaced Liquid theme with Next.js front-end

Decoupled content blocks into CMS-driven React components

Mobile-First Redesign

Stacked galleries, full-width CTAs, thumb-reachable “Add to Cart”

Sticky bottom bar on product pages

Performance Optimization

Image Optimization: Next.js Image component with on-the-fly resizing

Code Splitting & Prefetching: Inline critical assets; lazy-load non-critical

Caching & ISR: 5-minute revalidation for fresh content

Key Features & CRO Tactics

Dynamic Promotions CMS-editable BOGO and free-ship banners, personalized per user segment

Step-By-Step Recipe Guides Collapsible “How to Cook” section keeps main product detail above the fold

Social Proof Modules Real-time UGC carousel with embedded TikTok feed

A/B Tested Variations

Button color & microcopy tests → +22% click-through

One-click Add to Cart → −18% cart abandonment

Results & Impact

6-Month ROI Baseline 3.8× +280%

Performance Wins: LCP under 2 s boosted SEO rankings and organic traffic by 18%.

Conversion Gains: 33% uplift on mobile drove ~$150 K incremental revenue over six months.

Operational Efficiency: Enabled 10 new campaigns in first month; marketing now independent of engineering.

Technical & Design Highlights

Component-Driven UI: Reusable React/Tailwind modules for consistency and rapid rollout

Progressive Hydration: Hydrate critical interactive parts first, defer non-essential scripts

Accessibility & UX: WCAG-compliant contrast, semantic HTML, keyboard-accessible accordions

Analytics Integration: GA4 full-funnel tracking; Shopify Conversion API for offline attribution

Takeaways & Next Steps

Scalability: Headless setup supports new channels (PWA, in-store kiosks) with minimal rework

Continuous Improvement: Roadmap includes AI-driven recommendations, loyalty integrations, subscription upsells

Portfolio Impact: Demonstrates expertise in headless Shopify, Next.js performance tuning, and data-driven CRO—ideal for brands seeking high-impact e-commerce solutions.
