Advanced Tips for Fast Websites

Moving rendering to the server or at build time with SSR or SSG can massively improve your site’s performance. It's about delivering content to your users in the most efficient way possible, ensuring they can quickly access the information they need.

Modern front-end frameworks and libraries come with their own set of best practices for performance optimization. Whether you're using React, Vue, Svelte, or others, following these guidelines can help you achieve a more performant web application.

Switching to AVIF or WebP for your images is a significant leap forward in reducing load times. These formats use advanced compression algorithms to deliver high-quality visuals at a fraction of the size.

Using service workers and the Cache API to cache app shells and data on the client side can make your website feel incredibly fast and responsive. This technique is particularly effective for repeat visits and can even allow for offline functionality.

Google's Web Vitals provide specific metrics for making it feel fast and smooth for your users. Optimizing for these factors can greatly enhance user satisfaction and contribute to higher SEO rankings.

The contain property in CSS allows you to limit a component's impact on the rest of the page (layout, paint, and size). This can improve the rendering performance of the page by helping the browser make optimization decisions.

Lazy loading defers the loading of non-critical resources at page load time. Instead, these resources are loaded at the moment they're needed (like when scrolling to them). This can drastically reduce initial load times and save bandwidth for users.

By focusing on these advanced optimization techniques, you're enhancing user experience, boosting SEO rankings, and, most importantly, increasing conversion rates.
