Shopify Theme Migration (Ella → Horizon) – Clean, Fast & SEO-Optimised Rebuild I have an existing Shopify store currently built on the Ella theme, and I would like to migrate it to the Horizon theme. The goal is not just a theme switch, but a clean, high-performance rebuild with a strong focus on speed, SEO, and user experience. Project Requirements: Migrate website from Ella theme to Horizon theme Rebuild homepage with a clean, minimal, and professional layout (no clutter or unnecessary sections) Ensure fast loading speed and optimisation for Core Web Vitals Maintain SEO structure (URLs, metadata, content hierarchy) Build clear and well-structured product pages (separate sections for description, specifications, benefits) Optimise for mobile responsiveness and accessibility Implement simple and intuitive navigation for easy product discovery Integrate essential apps only (avoid unnecessary scripts) Important: I do NOT want a direct copy of the current layout. The site should be simplified and improved. Avoid overuse of Horizon blocks/sections — keep the design lightweight and efficient. The final website should be clean, modern, and suitable for a medical supplies business. Critical Requirement: The migration must be smooth with no downtime, no broken pages, and no disruption to existing functionality Existing products, collections, and data must remain intact Nice to Have: Experience with Shopify Horizon theme Understanding of SEO best practices and performance optimisation Please share: Examples of similar Shopify work (especially clean, fast stores) Your approach to ensuring performance and SEO Estimated timeline and cost Looking forward to working with someone who understands performance-focused Shopify builds.
