There are four factors that determine/affect your LCP Render Blocking Javascript (JS) and Cascading Style Sheets (CSS) Slow server response times resource load time Client-side rendering Let’s take a closer look at each of these factors and examine how you can optimize them. Render blocking JS and CSS Scripts (.js) and style sheets (.css) are the main culprits for LCP lagging significantly. You need to carefully determine which .js and .css are critical and which can be deferred during the initial page load time. Here are some things you can do to make sure your LCP doesn’t get bogged down with your scripts and style sheets: Minify CSS The CSS may contain some unnecessary characters, such as indents, extra spaces, or comments. You can minify the CSS, which will remove those extra characters.
This will help ensure that the browser doesn’t waste time processing these unnecessary characters during the initial page load. This, in turn, will help improve LCP. CSS lazy or Dominican Republic Phone Number inline Carefully examine the CSS elements. If there are certain unused non-critical CSS on your web page, be sure to defer them . You can find such unused CSS by visiting your page and pressing Control+Shift+I. This will open Chrome DevTools. Take a close look at the “Coverage” tab and locate “Unused Bytes”. Deferring these style sheets (CSS) during the initial page load will help improve your LCP. Also, identify CSS that are highly critical and used during page load time. Be sure to align these CSS elements.

This will ensure that the browser doesn’t have to process all of your code to find the useful CSS. A good practice would be to add these critical CSS elements to the <head> section of your page. Reduce JavaScript blocking time Javascript plays a very important role in page speed. Make sure that you are only serving critical Javascript files to your users. Any unnecessary Javascript code should be completely discarded. You can also compress Javascript to remove unnecessary spaces and indents. You can also use the defer and inline techniques mentioned above to segregate critical Javascript files. Slow server response time Server response time is very critical and can dictate overall page speed.
If the server takes longer to respond to browser requests, it will take longer to display the content to the user. This can significantly affect the PCL. Make sure your browser responds quickly to requests and delivers content as quickly as possible. You can also use caching techniques where important elements are stored on the server side when a user visits a website. This reduces the load on the server. If the CSS and Javascript are properly optimized, you may want to take a look at other resources that are slowing down your website. These resources could be L text files. Be on the lookout for resources that take longer than usual during the initial page load.

For images, a good practice is to compress them and make sure they are under 100kb. You can also use the Gzip tool to compress text files. A very useful technique is to use the unction to prioritize resources that are important and should be loaded first. This will help ensure that your memory-hungry resources don’t affect your first Content Paint (FCP). Here is an example implementation of th function: You can choose whether to preload a .js, .css, or image file. Many site owners now use the Javascript client-side rendering technique on their websites. By using client-side rendering, you can render the entire page directly on the user (browser) end.
