How do you ensure e-commerce stores load quickly?

Performance directly impacts sales - 1 second delay decreases conversions by 7%. Our optimizations: image optimization (WebP format, lazy loading, responsive images), CDN delivery (global content delivery network), code optimization (minified CSS/JavaScript), database optimization (efficient queries), caching strategies (serve cached pages when possible), critical rendering path (load visible content first), reduced redirects (minimize HTTP redirects), and performance monitoring (continuous optimization). Target: 90+ PageSpeed scores, under 2-second load time. Large product catalogues require strategic optimization: infinite scroll instead of loading 1000 products, image compression (80% size reduction, minimal quality loss), and efficient search (fast product finding). Mobile optimization particularly critical - mobile users have variable connectivity. We implement progressive loading (show content incrementally), priority loading (hero images first), and performance budgets (maximum page size). Many e-commerce sites are slow (4-6 seconds); ours load in 1-2 seconds. This competitive advantage increases conversions and improves SEO (Google uses speed as ranking factor).
