Shopify store owner slashes INP by 240ms with targeted optimizations

By PulseAugur Editorial · [1 sources] ·

A Shopify store owner significantly improved their website's Interaction to Next Paint (INP) score by implementing three key changes over six months. The INP, a metric measuring page responsiveness to user interactions, dropped from 380ms to 140ms. The most impactful change involved splitting a heavy, page-wide event handler into scoped listeners and deferring expensive operations, which alone reduced INP by 110ms. Lazy-loading the cart drawer JavaScript and optimizing its execution time contributed an additional 80ms improvement. AI
