What's included
Everything in our Shopify Speed Optimisation engagement
Every deliverable is scoped upfront. No surprises, no hidden extras.
PageSpeed 90+ Guarantee
We target a minimum 90 PageSpeed score on mobile and desktop for every speed project — with a clear action plan to reach it before we start.
Core Web Vitals Fix
LCP, INP, and CLS diagnosed and fixed at root cause — not masked with workarounds. Real field data improvements verified in Chrome UX Report.
Image & Video Optimisation
WebP/AVIF conversion, responsive srcsets, lazy loading, and video compression that eliminate the most common source of Shopify speed problems.
Script Audit & Deferral
Every third-party script audited — dead scripts removed, necessary scripts deferred. Most stores have 8–15 scripts they no longer use loading on every page.
Theme Code Review
Redundant CSS, render-blocking JavaScript, unused Liquid snippets, and inefficient loops identified and removed from the theme codebase.
Before & After Report
Full PageSpeed, Lighthouse, and Web Vitals report before and after with line-by-line explanation of every change made.

FAQ
Your Shopify Speed Optimisation questions answered
What PageSpeed score can you get my Shopify store to?
For most Shopify stores, we target 85–95 on mobile and 90–100 on desktop. The achievable score depends on your theme complexity and required third-party apps. We audit first and give you a realistic target before starting.
Why is my Shopify store slow even though I'm on Shopify's hosting?
Shopify's hosting is fast — the bottleneck is almost always theme code, unoptimised images, too many third-party apps/scripts, render-blocking fonts, or inefficient Liquid rendering. These are all fixable.
How much does page speed affect conversions?
Google data shows a 1-second delay in mobile load time reduces conversions by up to 20%. A store improving from 3.5s to 1.5s LCP typically sees a 15–35% conversion rate uplift within 30 days.
Do speed fixes break my store's design or functionality?
No — all changes are tested in a staging environment and reviewed before applying to live. We do not remove scripts or features without confirming they are genuinely unused.
Do you fix Core Web Vitals for Google Search ranking?
Yes — LCP, INP, and CLS are Google ranking signals. We fix each metric at root cause and monitor Chrome UX Report field data (not just Lighthouse lab data) to confirm real-world improvement.
