Every millisecond counts in e-commerce. Here are performance optimization tips that go beyond the basics.
Audit Third-Party Scripts
Tracking pixels, chat widgets, and analytics scripts all slow your store. Load them asynchronously. Defer non-critical scripts. Remove any tracking you do not actively use.
Optimize Font Delivery
Custom fonts add load time. Use font-display:swap to ensure text remains visible during font loading. Consider using system fonts for a faster experience.
Preload Key Resources
Tell the browser to preload your hero image and critical CSS. This prioritizes important resources over less critical ones.
Reduce Server Response Time
Shopify handles server infrastructure, but apps and custom code can slow response times. Review your app list and remove performance-heavy apps.
Use Critical CSS
Inline critical CSS in the head of your document. This lets the page render above-the-fold content without waiting for the full stylesheet.
Enable Predictive Search
Shopify's predictive search loads results as customers type. It feels faster and reduces the need for a full search page load.
Monitor with Real User Monitoring
Tools like Google Analytics and Shopify Analytics show real user speeds. Synthetic tests (PageSpeed Insights) are useful, but real user data tells you what customers actually experience.
