Shopify Speed & Performance Audit — Core Web Vitals Fix & Store Optimisation | £397–£1,497 | By Design UK

A slow Shopify store loses customers and rankings. Google uses Core Web Vitals as a ranking signal — and customers abandon slow pages within 3 seconds. The Speed & Performance Audit identifies every speed issue in your store and either fixes it or gives you an exact plan to do so.
