Shopify Speed & Performance Audit — Core Web Vitals Fix & Store Optimisation

£397–£1,497

Market Rate: £800–£3,000

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.

✅ What’s Included

📊 Core Web Vitals Assessment — LCP, FID, CLS and INP all measured and benchmarked against Google’s thresholds
🖼️ Image Optimisation — All oversized images identified, compressed and converted to WebP format where applicable
📱 App Audit — Every installed app assessed for performance impact — bloated or unused apps flagged for removal
💻 Theme Code Review — Unused CSS, render-blocking JavaScript and inefficient liquid code identified and documented
🔄 Lazy Loading — Lazy loading implemented for below-the-fold images and non-critical resources
🌐 CDN Configuration — Shopify CDN settings reviewed and optimised for your store’s asset delivery
🔤 Font Optimisation — Web font loading strategy reviewed and optimised to eliminate render-blocking
📋 Full Speed Report — Before and after scores documented with every issue and fix recorded
🛠️ Implementation — Fixes implemented directly in your theme where possible within the service scope
🔧 14-Day Support — Any speed regressions in the first 14 days investigated and resolved

⏱️ Timeline

3–5 business days from access to completed optimisation.

🎯 Who Is This For?

Store owners whose Google PageSpeed score is below 70. Businesses seeing high bounce rates. Anyone who has added lots of apps over time and suspects their store has slowed down.
