The most common causes are too many apps loading JavaScript on every page, unoptimized product images, bloated theme code, and render-blocking resources. Shopify stores are particularly vulnerable because apps inject scripts globally.

A single app can add 200-500ms to your load time. Most stores we audit have 15-30 apps installed, many redundant or loading on pages where they're not needed.

No. We test every optimization in a duplicate development theme before applying changes to your live store. We verify that checkout, product pages, and all app functionality work perfectly.

We never modify your live theme directly. You review and approve all changes before they go live, and you can revert instantly if needed.

Most clients see a 40-60% improvement in page load time. The exact improvement depends on your current state — stores with many unoptimized apps see the biggest gains.

We guarantee measurable improvement or you don't pay. Our average client sees a 28% increase in conversion rate after optimization.

Yes — we work with both Shopify Plus and standard Shopify stores. Plus stores have additional optimization opportunities through checkout customization, script tags, and headless architecture options.

For high-volume Plus merchants, we can also implement advanced optimizations like edge caching, custom storefronts, and Hydrogen/Oxygen migrations.

Yes — we include 30 days of performance monitoring after optimization. If anything regresses due to new apps or theme changes, we fix it at no additional cost.

We also provide documentation on how to maintain speed: which apps to avoid, how to evaluate new apps before installing, and best practices for theme customizations.
