What are some advanced techniques for website speed optimization?

To boost your website’s speed, try advanced techniques like lazy loading, which delays loading images or videos until you need them. From there, minify your CSS and JavaScript to shrink file sizes and speed up loading. Load JavaScript asynchronously so it doesn’t block the page from showing content. Also, use HTTP/2 to send multiple files at once efficiently. Combine these with image compression and smart caching for a faster, smoother experience.
