The 6 most common and highest-impact speed fixes for Shopify stores — what we focus on first.
Fix all three Core Web Vitals — Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint. Passing these metrics improves Google rankings and user experience.
Images are the #1 cause of slow Shopify stores. We compress, convert to WebP, implement lazy loading, and set proper dimensions — often cutting 40–60% of page weight instantly.
Third-party scripts from apps, analytics, and widgets block page rendering. We defer non-critical scripts, load analytics asynchronously, and eliminate unused JavaScript.
Bloated theme code, unused CSS, and inefficient Liquid templates slow every page load. We audit and clean the theme code layer — significant gains with zero visual changes.
Shopify's built-in CDN is powerful but often misconfigured. We optimize CDN settings, enable browser caching, and configure image CDN for global fast delivery.
A slow checkout kills conversions right at the finish line. We optimize checkout page load time, reduce payment script weight, and ensure mobile checkout is blazing fast.
Full Lighthouse + WebPageTest audit with prioritized issue list and estimated effort for each fix.
Reduce Largest Contentful Paint — hero image preloading, font display, and above-the-fold render path optimization.
Eliminate Cumulative Layout Shift — reserve image dimensions, fix ad slot shifts, stabilize font loading.
Improve Interaction to Next Paint — reduce JavaScript execution time, split long tasks, optimize event handlers.
Compress all product images, convert to WebP, implement responsive srcsets and lazy loading across the store.
Below-fold images, videos, and iframes loaded on scroll — reducing initial page weight by 30–60%.
Non-critical scripts deferred. Analytics and tracking loaded asynchronously. Unused JavaScript removed.
Shopify CDN settings optimized. Third-party resource preconnect and DNS prefetch configured.
Remove unused CSS, optimize Liquid template rendering, minify JS/CSS bundles, clean up section code.
Measure each app's performance impact. Identify which apps are slowing your store and how much.
Font display swap, subset loading, preload declarations, and self-hosting where beneficial.
Checkout page load optimization, payment script tuning, and mobile checkout speed focus.
For Standard and Full Optimization packages: if we don't improve your PageSpeed score by at least 15 points, we'll continue working until we do — at no extra charge. We've never had to invoke this guarantee in 100+ optimizations. Start your optimization →
