Where We Find the Speed
Shopify performance problems have consistent patterns. We know where to look first.
App Script Audit
Every installed app adds JavaScript to your storefront — often unconditionally. We measure each app's render-blocking impact and either defer, consolidate, or replace it.
Theme Code Review
Poorly written Liquid, synchronous JavaScript, render-blocking CSS, and unused theme features are identified and cleaned up.
Image & Media Delivery
Product images are the largest assets on most Shopify stores. We implement responsive srcset, WebP conversion, lazy loading, and CDN delivery for media.
Core Web Vitals Remediation
LCP, CLS, and INP issues traced to their root cause in the theme or apps, then fixed and re-tested with real-device Chrome UX Report data.
Third-Party Script Deferral
Chat widgets, review apps, and analytics pixels are deferred until after the page is interactive so they don't block the critical render path.
Checkout Optimisation
Shopify's checkout is hosted by Shopify, but there are still optimisation opportunities in cart drawer code and the transition to checkout.
How It Works
01
Baseline
We benchmark your store with PageSpeed Insights, WebPageTest, and Chrome UX Report to establish real-world scores, not just lab numbers.
02
Diagnose
Each bottleneck is traced to its source — specific app, theme code, or Shopify platform behaviour — so we fix causes, not symptoms.
03
Implement
Changes applied on a duplicate theme and benchmarked before going live. We never push untested performance changes to production.
04
Handover
Documented recommendations for ongoing performance hygiene — including which apps to avoid and how to evaluate new ones before installing.
