1. How to Improve Largest Contentful Paint (LCP)

When contents in your site take a long loading time, your site users or visitors get frustrated, and thus they leave your site. Therefore if your website’s LCP scores are poor, you should take action immediately to improve them.

Of course, your solution will depend on the causes of your site’s poor score. Some common reasons you have to deal with LCP problems are render-blocking CSS and JavaScript and a slow server. However, to improve your site’s LCP, you can follow the methods below:

    • Large Elements Elimination
    • Minify blocking CSS and JavaScript
    • Use a CDN (Content Delivery Network)
    • Leverage Lazy Loading

If following these above solutions fails to improve your website’s LCP score, then you need to upgrade your overall web hosting. High-quality hosting increases the overall site performance and results in better servers.


2. How to Improve First Input Delay (FID)

FID’s ideal time is 100 ms or less. If a longer time requires in your site than the 100 MS, then your UX will suffer. Optimizing your JavaScript is the most effective method of improving the score of FID. In a variety of ways, you can do that. Minimizing JavaScript is a common tactic. If you do so, the visitor will get the chance to interact with your website while JavaScript is still loading in your browser.

Using the Async JavaScript plugin, you can do that. In addition, you can eliminate the above-the-fold content’s render-blocking JavaScript using this free tool. This tool helps to boost your website’s search engine rankings and improves page speed, FID, and UX.

Removing the unnecessary third-party scripts is another way of improving FID. Too many scripts make the response times slower by clogging the network. Also, you can use the browser cache. The cache will make the content loading easy on the user’s browsers. Also, the JavaScript tasks become quicker due to the use of cache.


3. How To Improve Cumulative Layout Shift (CLS)

High CLS causes by the elements on the page shift when the page loads, and this high CLS isn’t good. The user can become confused or click on the wrong element due to visual instability. Ideally, the value of CLS should be less than 0.1. If your site’s CLS is higher than 0.1, you should follow some steps to improve this value.

Some of the steps are mentioned below:

    • Specifying the image dimensions is the first step of it. The CLS score increases significantly if you fail to set attributes for your image’s width and length. The same applies to any type of media, like videos, GIFs, and infographics.
    • Dynamic ads are the second important consideration. Your website’s ads should have their own reserved space. And it will help to give a better experience to your user. For example, your site visitors will have difficulty reading the content if you place large ads on the top page.
    • On your website’s pages, reserve the embeds and iframes spot, and it’s another way of improving the CLS score. However, these elements can affect your website page’s layouts if they don’t have well-defined dimensions.
