Largest Contentful Paint (LCP)

Largest Contentful Paint


The largest contentful paint, also referred to by the abbreviation LCP, is a part of the three core web vitals. It is a metric that showcases the speed at which the content on a particular website loads up. It is quite significant in helping the web developer improve the viewer’s experience, especially when the user starts to load the page. It moves to the loading of the biggest picture on the page.


How to See LCP?

There are several ways through which you can see and optimize LCP. The most popular ways are to get help from some external tool, use the chrome extensions or have assistance from Google Lighthouse.


Optimize LCP

Optimizing LCP surely enhances your ability to bring more traffic to the website by providing a better user experience to the viewers. As the Website Load Speed increases with the enhanced LCP score, the reader comes to your website every time he needs some information. Obviously, he wouldn’t want to waste his time on a website with snail speed.


Once LCP is optimized, you will be able to see a huge rise in organic traffic as a direct consequence of it!

Some of the best ways to optimize LCP are:


Smaller is Faster

Using smaller images on the web pages will ensure that their content loads faster. You don’t only need to use the right format for the pictures but also need to compress them into an optimal size. This way, you would be able to balance out the visual quality of the image with its output size. While changing the URL parameter, you can easily manage the image’s compression level.


Closer is Faster

If your images load from a closer location to the user, they will take lesser time. This way, the viewer could witness the webpage faster rather than getting annoyed by the slow speed and closing the tab. You will have to use the content delivery network, also known as CDN. Rather than letting the images load from your server, let them load closer to the user.


Use the Same Server IF Possible

This is a great way to ensure your page and its content load faster for the user. Shifting the content to the reader’s server will ensure that even if you have used big sizes pictures, they won’t take much time to open completely.


Cache What you Can

To ensure that the data on your web pages load faster, you need to cache everything possible. On top of that, if you can cache every image on the device of the user, things will work faster. Using CDN notes will reduce the loading time effectively. With this, the LCP of your website will surely improve.


Prioritization of Resources

A resource that is of prime importance in the content must be loaded perfectly for the reader to view the webpage easily. However, sometimes, the browser does not prioritize some crucial content elements.


One major example is the banner image that might be turned into a background image. Hence, when till the time your CSS file downloads, the main image may go in the back view. This majorly affects the way your reader may end up perceiving your content. Therefore, you need to preload the resources you want to prioritize.


Cumulative Layout Shift (CLS)

Cumulative Layout Shift (CLS)

CLS, also known as Cumulative layout shift, is the ability of the webpage to make unexpected shifts throughout its life. A huge CLS score comes by when immediately after the banner loading, the page jumps down automatically. This surely adds to the readability pleasure of the visitor.


How to See CLS?

There are various manners through which you can check the CLS score of the website and decide whether it’s working in your favor or not. There are numerous tools that help you do that efficiently. For instance, you can use the URL of your website on PSI to calculate all three Core Web Vitals. PSI, also known as PageSpeed Insights, will send you a complete report with an extensive summary of your page’s performance. Once you analyze it, you will be in a better position to decide whether you should work a little extra on the CLS or not!


If the score comes out to be around ninety or higher than that, your website is already working pretty well!


Optimize CLS

Optimizing CLS to make your website perform better is important! If you do so, you will be able to rank higher on Google, as it directly affects the SEO. In terms of single web pages, those that have a CLS score of above 0.25 surely require CLS optimization.


First Input Delay (FID)

First Input Delay (FID)


FID, also known as first input delay, is the amount of time the website needs to move from the user’s first interaction with the side to the response towards this interaction. If this amount of time is high, it will affect user performance greatly. SEO experts always aim to improve the FID score and minimize the time required for the webpage to interact with the viewer.


What Causes the Delay?

Low FID happens because the browser’s main thread cannot respond to the viewer immediately as it is busy performing some other function. Once it is done with that one, it moves to the next action.

The most probable reason it happens is that the browser is loaded and gets busy. This, executing a heavy JavaScript file, becomes too lethargic for it.


Optimize the FID

Optimization of FID is necessary to ensure your viewer returns to your website whenever he needs some information. The major reason behind the slow interaction rate is the heavy JawaScript execution that causes the delay. Hence, to optimize FID, you should either lessen the amount of JavaScript each webpage executes or cut the big codes into smaller elements.


Other Performance Metrics

Apart from the three performance metrics discussed above, there are others that affect a website’s performance. They are as follows:


First Contentful Paint

This is basically an indication by the browser that the page is in the loading process, and it becomes the first feedback to the viewer. This score is to be improved to bring organic traffic to the website. For instance, Google recommends a score of around 1.8 seconds to ensure your visitors get a pleasant experience on your website. A period more than that can affect his experience negatively.


Speed Index

The content on your webpage is the most important thing for the viewer. If the elements of this content are not visibility populated on the page, it might affect the user’s experience. All the visible parts of your web page should be displayed in the shortest possible period. Speed Index, also known as SI, is the metric that measures it.


Time to Interactive

TTI, also known as the time to interact, is basically the kind of web performance that talks about the thread inactivity after the conclusion of the last long activity and the break of five seconds by the network. When the site ‘looks’ ready, it should interact with the visitor immediately. JavaScript effect and influences time to interact directly. It is a good indicator if this score is lower than 3,8 seconds on the web pages.


Total Blocking Time

The load responsiveness of your web page when input by the user blocks it is called the total blocking time. This may happen due to any input activity by the user, like clicking the mouse or pressing the keyboard. If the TBT score is high, it means that web pages are not able to respond to the user’s actions quickly.


Page Performance Score

Page performance score, just like the name says, is all about the speed at which the web page loads and displays the content to the user. This score affects the ability of the website to interact with the users and the level of usability it offers. Hence, if your webpage loads faster, it means it has an impressive page performance score.
