Why Speed Matters
A one-second delay in page load time can result in a 7% reduction in conversions. In today's fast-paced digital world, speed is everything.
Image Optimization
Images are often the largest assets on a page. Here's how to optimize them:
- Use modern formats like WebP and AVIF
- Implement lazy loading for below-the-fold images
- Serve responsive images based on viewport size
- Compress images without sacrificing quality
CSS and JavaScript Optimization
Minify and concatenate your CSS and JavaScript files. Remove unused CSS rules and defer non-critical JavaScript.
Caching Strategies
Implement browser caching with proper Cache-Control headers. Use a content delivery network (CDN) to serve assets from servers closest to your users.
// Example: Service Worker Cache Strategy
self.addEventListener('fetch', event => {
event.respondWith(
caches.match(event.request)
.then(response => response || fetch(event.request))
);
