As part of a long-term project, I conducted a full Core Web Vitals audit and optimization for a WooCommerce store with a complex plugin setup and dynamic content. Key steps included: - Tuning server-level cache (OpenLiteSpeed, Redis, Memcache) - Tailoring LiteSpeed Cache plugin to avoid conflicts and excessive purging - Selective script/style loading to reduce CLS and TBT - Optimizing third-party assets (fonts, tracking tools) Result: all PageSpeed Insights scores in green, with CLS and INP consistently excellent — both for mobile and desctop users.
The client’s WooCommerce store sold products with thousands variations of possible attribute combinations — often leading to performance issues and slow product selection. I redesigned the variation system from the ground up by implementing: - A custom variation selection structure - Advanced pre-processing and caching for new structure - A lightweight JS-driven interface to replace WooCommerce’s default slow dropdowns - Simplified nice-looking UI for product selection As result: - Instant response for product selection (25–40ms INP) - Better user expirience on the core e-commerce flow
