Hey community! In today’s digital world, speed is crucial. A fast website keeps users engaged, improves SEO, and drives conversions.
✅ Optimize Images
Images often take up most of the page weight. Switch to modern formats like WebP or AVIF for better compression. Tools like ImageOptim, Squoosh, or Sharp can automate optimization as part of your build process. Always set explicit width and height attributes to prevent layout shifts.
✅ Enable GZIP or Brotli Compression
Compress text-based assets (HTML, CSS, JS) on your server. GZIP is widely supported, but Brotli can achieve even better compression rates. Enable these through server configurations (Apache/Nginx) or your CDN settings to significantly reduce transfer sizes.
✅ Lazy-Load Images & Videos
Loading all media at once slows everything down. Instead, delay loading with native loading="lazy" on and tags, or use Intersection Observer for more control. This reduces initial load time and saves bandwidth.
✅ Minify CSS, JS, and HTML
Whitespace and comments add unnecessary bytes. Use tools like Terser, UglifyJS, html-minifier, or your build system (Webpack, esbuild, etc.) to minify files, decreasing download sizes and speeding up parsing.
✅ Use a CDN
A Content Delivery Network caches your static assets on servers worldwide. This reduces latency by serving users from the nearest location. Popular options include Cloudflare, Fastly, and AWS CloudFront.
✅ Reduce HTTP Requests
Each request increases load time. Combine CSS and JS files, inline critical CSS, use SVG sprites, and remove unused libraries or fonts. Tools like PurgeCSS can remove unused CSS to keep bundles lean.
✅ Implement Server-Side Rendering (SSR)
For dynamic apps, especially those built with React, Vue, or Svelte, SSR can significantly improve Time to First Byte (TTFB) and initial render. This helps content show up faster for users and bots.
✅ Cache Smartly
Set cache headers like Cache-Control: max-age=31536000, immutable for static assets. Use hashed filenames (like app.9c8f.js) to allow long-lived caching without stale content.
✅ Preload Critical Assets
Guide the browser to prioritize key resources (fonts, scripts) using . This reduces delays in rendering important content.
✅ Audit with Lighthouse
Regularly test your site with Google Lighthouse, Page Speed Insights, or Web Page Test. These tools provide actionable insights on performance, accessibility, and best practices.
