1. Minimize Render-Blocking Resources
Identify and eliminate or defer render-blocking JavaScript and CSS files. Leverage tools like Lighthouse or WebPageTest to pinpoint bottlenecks.
2. Optimize Critical Rendering Path
Prioritize loading the CSS necessary for above-the-fold content to render quickly. Inline critical CSS or use techniques like preload to speed things up.
3. Defer Non-Critical CSS
Use the `media` attribute in your link tags to load non-critical CSS asynchronously, preventing it from blocking the initial rendering.
4. Leverage Browser Caching
Configure proper cache headers for your static assets (images, CSS, JavaScript) to enable browsers to cache them for subsequent visits.
5. Optimize Images
Compress images without sacrificing quality, use appropriate image formats (WebP), and implement lazy loading for images below the fold.
6. Minimize DOM Size
Keep your DOM size lean by removing unnecessary elements and optimizing your HTML structure. A smaller DOM translates to faster parsing and rendering.
7. Use Efficient Selectors
Avoid overly complex CSS selectors, as they can significantly impact rendering performance. Use specific and efficient selectors whenever possible.
8. Avoid Forced Synchronous Layouts
Carefully manage JavaScript interactions with the DOM. Avoid forcing synchronous layouts (layout thrashing) by reading and writing to the DOM in separate phases.
9. Reduce JavaScript Execution Time
Profile your JavaScript code to identify performance bottlenecks. Optimize code for speed and consider code splitting to load only necessary code on initial page load.
10. Use a Content Delivery Network (CDN)
Distribute your website's assets across multiple servers using a CDN. This reduces latency and improves loading times for users across the globe.
