Speed Optimization

Every 100ms of page load time costs 1% in conversions — and most Shopify stores are leaking sales from slow load times. I diagnose and fix every performance bottleneck, from bloated themes and unoptimized images to render-blocking scripts and oversized bundles.

What's Included

Everything you get

Core Web Vitals Audit

Full LCP, FID/INP, CLS audit using Lighthouse, WebPageTest, and real-user monitoring (CrUX data) to find every bottleneck.

Image Optimization

Convert to WebP/AVIF, implement responsive srcsets, add lazy loading with priority hints, and use Shopify's CDN image transforms.

JavaScript Optimization

Defer non-critical scripts, eliminate render-blocking JS, remove unused app scripts, and reduce main thread work.

Liquid & CSS Cleanup

Remove duplicate Liquid calls, eliminate unused CSS, critical CSS inlining, and preload/preconnect for key resources.

App Script Audit

Audit every installed app's script impact. Replace slow apps with lightweight alternatives or custom-built solutions.

Font Optimization

Subset fonts, implement font-display: swap, self-host critical fonts, and eliminate layout shift from web font loading.
