• Product Data Modelling : Design and implement a robust product taxonomy (collections, tags, product types) optimised for hardware. Set up variants and custom fields to clearly display technical specifications (e.g., memory, processor, battery) and manage complex inventory attributes (colour, storage capacity, network).
• App Integration : Install and configure essential third-party apps for detailed product filtering, customer reviews, and potential warranty / insurance integration.
• UX Optimisation : Ensure the site provides an excellent user experience, focusing on clear navigation, high-resolution product imagery, and effective display of product specifications.
