WooCommerce Performance: From 3s to 0.6s Load Time

The Problem

A UK fashion retailer — £80k/month revenue, PageSpeed score 31/100, LCP 4.8s. Our constraint: do not change the hosting plan.

What We Did

Combined 23 CSS files and 18 JS files into 2 bundles each, cutting page weight by 60%. Converted all product images from 800KB JPEGs to 45KB WebP. Added Redis Object Cache — TTFB dropped from 1.2s to 0.18s.

Results

PageSpeed 31 → 94. LCP 4.8s → 0.6s. Conversion rate +28%. Revenue +34% the following quarter with zero change to the hosting infrastructure.

Competently architect intermandated deliverables with client niches and continually build cross-media growth strategies without robust compromises.
