Will removing apps hurt our conversion rate?

We only recommend removing apps whose measured contribution is smaller than the speed cost they impose. Every removal is data-backed.

What Lighthouse score can we realistically hit?

Most mid-market Shopify stores can hit 70–85 on mobile after optimisation. Beyond that requires deeper theme rewrites or a headless build.

Shopify Speed Optimization

Every 100ms of latency on a Shopify PDP costs approximately 1 percent conversion. Our Shopify speed optimisation service ships measurable Core Web Vitals wins — usually 20–40 points on mobile Lighthouse — in a two-week engagement.

Why this matters

Reduce third-party app JavaScript bloat
Optimise Liquid render performance
Convert images to WebP + AVIF with correct srcsets
Defer non-critical JS and inline critical CSS
Move analytics and pixels to Shopify Web Pixels API

Where Shopify stores actually slow down

In audits, the top offenders are app JavaScript (reviews, upsells, chat), oversized hero images, uncached third-party pixels, and Liquid loops with N+1 metaobject queries. Fixing those four buckets usually delivers 90 percent of the wins.

Our speed optimisation process

Week 1: full audit + before/after scores per template. Week 2: implementation on a duplicate theme, staged in preview and only pushed live after visual QA. We report Lighthouse deltas and real-user Core Web Vitals from Search Console.
