Speed Optimization for Shopify Stores
Slow Shopify stores lose revenue. 53% of mobile users abandon a site if it takes longer than 3 seconds to load, Google uses Core Web Vitals as a ranking factor, every 1-second delay in page load time can reduce conversions by 7%, and Amazon found that every 100ms of latency cost them 1% in sales.
What Causes Slow Shopify Stores?
- Unoptimized images — the #1 cause of slow Shopify stores
- Too many apps — each app adds JavaScript and HTTP requests
- Render-blocking CSS/JS — blocks page rendering
- Slow theme code — poorly coded themes are slow by default
- No CDN — serving images from the wrong server
- Lack of caching — no browser or server-side caching
