Core Web Vitals Performance WooCommerce

WooCommerce Store Performance Overhaul

The client’s WooCommerce store was slow, with poor Core Web Vitals and a frustrating mobile shopping experience. I optimised templates, reduced unnecessary requests, improved asset loading, and cleaned up performance bottlenecks.

How it happened

An online store lives or dies on mobile speed. This is how this one got it back.

A store losing its mobile shoppers

Five seconds to a usable page is an eternity in a checkout flow. The store sat at 42 on mobile with every Core Web Vital failing — product pages dragged, interactions lagged at 412ms, and the templates were hauling requests the storefront never used.

Template-by-template, without touching the storefront

WooCommerce performance work is template surgery. I went through the store’s templates one by one, cut 18 unnecessary requests, restructured asset loading so nothing render-blocking remained, and took 62% off the page weight — with the shop looking and working exactly as before.

A checkout that keeps up with its customers

Mobile 42 → 96, desktop 78 → 99. LCP down from 5.2s to 1.4s, layout shift from 0.32 to 0.02, interactions from 412ms to 87ms — Core Web Vitals passing on the pages that earn the revenue.
