What is Core Web Vitals?

Core Web Vitals are page engagement cues that assess a website’s user experience. That is, these cues indicate how quickly users will be able to engage with your website and the type of outcome they will get. These cues also indicate how simple it is for users to access the website.

Your page experience rankings will increase if you improve your user experience and make your website better overall.

There are three metrics in the Core Web Vitals set:

  1. Largest Contentful Paint (LCP): This is a metric that calculates how quickly a website’s largest element (images, videos, animations, text, and so on) can load and display.
  2. Cumulative Layout Shift (CLS): This makes sure that a website’s pages are free of sudden, perplexing motions that may distract users from accessing the content.
  3. The First Input Delay (FID): This metric measures how reactive a website’s pages are the first time users interact with them. It also assesses how quickly a website’s browser will return a result to users.

5 Guidelines to Help You Boost Your Core Web Vitals

You should run a fast test of website performance analysis to see how well your website performs concerning core web vitals. You can do this with Google tools like Search Console and Page Speed Insights, as well as other tools like GTmetrix.
It’s better to compare data and optimizing your page more effectively if you run success reports with different tools.

1. Limit the number of times JavaScript (JS) is executed

If your FID score is low, it means your page interfaces with users for more than 300 milliseconds. You should think about improving and reducing your JS performance. This reduces the time it takes for your browser to execute JS code and display the article.

It’s also important to use as little space as possible. What is the reason for this? When your site’s code sends a request to the browser, it creates a new memory block, which disables JavaScript and can cause the page to load slowly.

Deferring unused JS, according to Google, is one way to reduce the execution time.

To check if your website has any unused JavaScript, follow these steps:

  • To begin, go to your website and right-click on it, then select ‘Inspect.’
  • Then go to ‘Sources’ and search at the bottom for three dots. You should use a tool called ‘Coverage.’ After you’ve added it, hit the load button.
  • When the load is complete, you’ll be able to see how much JavaScript isn’t used on your tab.

When you’ve figured out how much JS you have leftover, you should start cutting it down. You can do it in a variety of ways, one of which is code splitting. This means breaking up a JavaScript package (a set of files bundled together to avoid making too many HTTP requests to load a page) into smaller chunks.

2. Make use of lazy loading

If you use photos on your blog, it’s critical to use lazy loading to protect your site’s UX and core web vitals ratings. Lazy loading helps you to load photos at the precise moment as users scroll down the page, preserving the website’s loading speed and ensuring a top-notch LCP ranking.

3.  Compress and refine files

Images, on the other hand, are the most important elements on several websites. As a result, optimizing them is critical because it can make your page greatly lightweight, improving loading speed, LCP ratings, UX, and search engine rankings.

By compressing images with tiny jpg and optimizing your LCP performance, you can reduce the total page size. You might believe that image compression reduces image quality or reduces resolution. Currently, the difference is only visible when you zoom in or if the image is saved in the incorrect format. Often try to save landscape images in jpg format and graphics in png format.

4. Make sure the photos and embeds are the right sizes

A CLS score of more than 0.1 is considered low, and it is typically triggered by elements in the CSS file that lack dimensions, such as images, ads or embeds. Dimensions do matter if you want to increase your CLS ranking. Setting the correct width and height allows the browser to designate an appropriate lot of space on the page when the element loads.

5. Reduce the time it takes for your server to react

Long server response times will harm not only your SEO but also your user experience.
Use Time to First Byte (TTFB) to determine server response time. This metric determines when the user’s web browser detects the first byte of your page’s content.
The response time of a server should be less than 600 milliseconds, according to Google.

Note that the back end of your website interacts with the front end, so ensure the back end is optimized to have the ultimate user experience in terms of loading speed, visual consistency, and functionality.
