How do I reduce page load time?

Reducing page load time involves optimizing multiple aspects. Compress and optimize images using modern formats like WebP, implement lazy loading for below-the-fold content, minimize CSS and JavaScript through minification and tree-shaking, use code splitting to load only necessary code, enable browser caching, use a CDN for static assets, optimize server response times, reduce redirects, and eliminate render-blocking resources. Prioritize above-the-fold content loading first. Use performance monitoring tools to identify bottlenecks. Example: A site reduced load time from 6 seconds to 1.8 seconds by optimizing images, implementing code splitting, enabling caching, and using a CDN.
