Last week we reviewed how to understand Google's PageSpeed Insights report , so it's time to work with these warnings that PageSpeed Insights provides us to improve the speed and performance of your website.
Use the following checklist to drive performance improvements for your website:
1. Minimize main thread work
The main thread is where the browser does most of the work needed to display a page. If it is blocked, users are unable to perform any tasks. This results in slow loading times, unresponsive pages, and a poor laos telegram data user experience. Minimizing the work of the main thread allows the browser to paint pixels on the screen faster and be more responsive to the user.
2. Offers images in next-generation formats
Next-generation image formats like JPEG 2000, JPEG XR, and WebP are the result of applying modern compression techniques to older image formats (.jpeg, .png, .bmp). Of these formats, WebP is the closest to becoming the new default format. Serving images in next-generation formats significantly reduces file size while maintaining the same quality.
3. Eliminate resources that block processing
Some CSS and JavaScript files (such as stylesheets, script tags) and images can be marked as render-blocking resources. As the browser traverses the HTML of a page, these resources can intercept the page. The browser must stop what it is doing, download, parse, and execute them. It removes render-blocking resources so that crucial actions such as displaying (rendering) the page can be performed.
4. Minimize resources
Reducing the size of your HTML, CSS, and JavaScript files is a crucial part of speeding up your website. You can lighten up code files by minimizing resources and compressing them. Both are low-effort, high-reward optimizations and it's smart to do them all at once.
5. Snooze off-screen images
Lazy loading of off-screen images (also known as image lazy loading) refers to the use of a set of techniques to load only the images that visitors are currently looking at. Off-screen images become visible only when the user navigates to them. Deferring them ensures that the most critical resources are loaded first.
6. Serve static assets with an efficient caching policy
Of all the ways to improve website performance, caching is the most fundamental. If you want to speed up your website performance, reduce the load on your server, and provide visitors with an exceptional experience, you definitely need to have an efficient caching policy in place.
