What Are Google Core Web Vitals?

Google Core Web Vitals are the most updated tool for helping with website analysis. Core Web Vitals is a very new program aimed at measuring and improving web user experience.

Rather than focusing on basic metrics such as the time it takes for your full website to load, Core Web Vitals analyze how your WordPress site performs for generating a great user experience.

Users are concerned about how quickly they can start engaging with a website. It is exactly what the Core Web Vitals attempt to evaluate with their measurements.

Why are Core Web Vitals Important for Websites?

Google has started considering Core Web Vitals as a ranking factor from June 2021, therefore these indicators may have an impact on your SEO success. Core web vitals actually a list of issues of a Website.

The new Page experience signals will include HTTPS security, mobile-friendliness, safe browsing, and invasive interstitial guidelines.

Core Web Vitals influence both desktop and mobile organic results, whether or not your site is featured in Top Stories in search results. Earlier, to feature in Top Stories, your site had to use AMP.

When Google implements this update, it is no longer be an issue, but the site will still be required to reach precise minimum Core Web Vitals scores to feature in Top Stories in the future.

Furthermore, all of the Core Web Vitals parameters must be completed to boost organic ranking. Additionally, the Core Web Vitals score for non-indexed pages may be significant.

If you want to improve your SEO performances, increasing your Core Web Vital scores is a must you have to do.

What are the three core Web vitals?

The following metrics are considered the most significant by Google when it comes to ensuring a better user experience.

Current Core Web Vitals are:

  • Largest Contentful Paint (which measures loading performance),
  • Cumulative Layout Shift (which measures visual stability), and
  • First Input Delay (which measures response time; interactivity)

Largest Contentful Paint (LCP)

LCP stand for “Largest Contentful Paint” which is the measurement of the time it takes for the largest type of content for downloading from your computer. It might be an image or just plain text, depending on your preference. Whatever it is, when it has loaded, the website appears to be fully operational.

The Largest Contentful Paint only considers content that is visible to the user in their viewport. Your LCP score will not be affected by any photos that appear below the fold.

Your LCP must be less than 2.5s if you expect to get a passing grade.

Cumulative Layout Shift (CLS)

The CLS is a tool that measures the stability of the page while it is being loaded. It takes into account all of the changes that can occur when photos are loaded delay or font styles change. Even simple elements such as buttons might cause unpredictable shifting on the page.

If your items are shifting suddenly (and by a factor of more than 0.1), you have a CLS problem that has to be addressed.

First Input Delay (FID)

The FID is a metric that evaluates how quickly a browser becomes functional. This implies that visitors will be able to interact with the exhibit and receive feedback. Actions like clicking links, tapping buttons, and checking boxes are examples of what it entails.

This metric can be passed if users can complete tasks such as filling out forms and surveys in less than 100 milliseconds.

How to measure your Core Web Vitals score for WordPress?

One of the most challenging parts of Core Web Vitals is their attention to user-friendliness. This is not a collection of esoteric metrics and is difficult to verify. As an alternative, there are a variety of official Google tools for evaluating and repairing your website that can make the process much simpler.

In terms of testing, there are two main areas to be aware of: lab testing tools and field testing tools. Field testing tools are supported by real-world data collected from genuine users who have opted into the Chrome Customer Experience Report to provide feedback. As a result, they become more valuable in terms of Core Web Vitals.

We’re going to concentrate on two alternatives:

  • Use the Google Search Console for the Google Core Web Vitals report.
  • Use the Page Speed Insights test for both field and lab reports.

First, check the Google Core Web Vitals report as it will let you know which URLs are causing the problem.

Using Google Search Console

Step 1: When you enter the console, look for Experience, and then Core Web Vitals at the bottom.

Step 2: Click on the Core Web Vitals. Then, you’ll be sent to a full-site assessment that categorizes each URL as Good, Needs Improvement, or Bad.

Take some time to read through the guide to using Google Search Console with WordPress if you’ve not already performed so.

How to Improve Your Core Web Vitals in WordPress:

It’s not difficult to improve your core Web Vitals score for WordPress. You can pass easily the Web Vitals score if you follow few simple performance enhancement techniques.

1. Optimize the Website Hosting

optimize website hosting

Your WordPress hosting provider is the most important factor in the success of your website.

They may optimize their servers for WordPress, giving your website a strong foundation on which to grow.

For a rising website, you are recommended to use SiteGround Hosting. They are one of the WordPress hosting companies that have been officially approved.

SiteGround employs Google Cloud Platform for their servers, as well as superfast PHP, to provide your website with the performance increase it requires.

SG Optimizer is a WordPress core web vitals plugin that is utilized by more than a million websites. It instantly performs additional performance optimizations and activates built-in caching, which performs all of the functions of WP Rocket and more.

However, it is a concern that their SG Optimizer plugin only operates with SiteGround hosting accounts, but these security optimizations are available on all plans, including the lowest ones.

If you are running a different WordPress hosting provider, you are recommended to use WP Rocket in conjunction with a few additional tools to improve your core web vitals score.

WP Rocket is the most effective WordPress caching plugin available on the market. It enables you to quickly and easily configure caching on the WordPress website without having to get into the technical aspects of server administration.

2.Increase the FID (First Input Delay) Score

Input Delay is a metric that measures the time that elapses between when a user clicks on something on the website and when their browsers begin to process elements.

That is why using a better web hosting service, or even a managed WordPress hosting platform, is the most significant recommendation for improving it.

The use of a caching plugin, such as WP Rocket, is another simple technique to boost your FID score. It includes a built-in feature that enables you to optimize the delivery of your files to your recipients.

Step 1: First, you have to install and then activate your WP Rocket plugin.

Step 2: Now, go to the Settings. From settings, click on the WP Rocket page.

Step 3: Once you enter the page, navigate to the File Optimization section.

Step 4: Make sure the ‘Load JavaScript deferred’ option is checked. You may have to scroll down to find it.

Step 5: To save the changes, click on the Save Changes option.

3. Increase the score for Largest Content Paintful (LCP)

The Largest Content Paintful (LCP) is the content portion of a page that is technically the largest inside the frame of the page. For example, the featured picture or the article text on a blog post may be included under this category.

The greater the speed with which this information loads, the higher your LCP score will be.

All you have to do is scroll down to the test results and click on the ‘Largest Contentful Paint element‘ option to see the results.

You’ll be able to examine the criteria that were taken into consideration for the LCP score. If the image is large, consider replacing it with a smaller version or with a lower quality. You should also have knowledge about how to optimize images for web performance without a plugin.

If the document is text, you can divide it into headings and paragraphs.

4. Optimize the Images in WordPress

Too large pictures are another major reason for a poor core Web Vitals score. Many WordPress users include high-resolution pictures on websites, that take longer to process and are usually unnecessary. In order to solve this issue you need best image optimization plugins for WordPress. Image optimization plugins will automatically optimize your all images.

For mobile users, this is even more challenging. Your core web vitals WordPress theme will automatically resize the image to fit the user’s mobile screen, but they will still load a larger file.

5.Increase the CLS (Cumulative Layout Shift) Score

When separate items on a web page load slowly and make other items on the page move, the Cumulative Layout Shift (CLS) score is affected.

Go to the Page Speed Insights results and expand the ‘Avoid large layout shifts’ tab to see which factors affect the CLS score.

This will display the factors that have the most impact on the layout shift during page load.

You must provide the dimensions (width and height) of the elements to the browser such as picture, video embedding, ads such as Google AdSense, and more to ensure that your page’s visual layout will not change when other elements load.

The height and width of the photos you provide are automatically added to WordPress. However, in addition, you can verify all the other media to ensure that they all have properties of height and width.

Using the Inspect Tool is one technique to do so. Just right-click and select Inspect for opening the console for the developer.

The source code for multiple pages can be highlighted by pointing and clicking on them. You can check if the item’s width and height properties are set there.

6.Use CDN for boosting Web Vitals Score

Use cdn to Optimize google core web vitals

The content delivery network, or CDN, is a third-party system that helps you to offer static material from many servers all over the world.

This enables you to download static materials such as photos and CSS from the servers closest to them. It also minimizes the load on your page, allowing additional items to load.

A cloud firewall app with a built-in CDN service, such as Sucuri, can be used. Sucuri also aids in the blocking of harmful and spam requests, freeing up even more resources on your website.

As an alternative, you can also use Cloudflare free CDN. It includes a simple firewall and CDN solution that will boost the web vitals score of your website. Sometimes database causes “Error Establishing a Database Connection error“. Fix it soon..

7.Remove the Render Blocking elements

Render blocking elements are those that take longer to load but prevent other components from loading before them. This has an impact on your total Web Vitals score as well as the user experience on the site.

The render-blocking elements will be highlighted in the Page Speed Insights results. They are mainly JavaScript or CSS files introduced by WordPress plugins, as well as third-party programs such as Google Analytics, Google Ads, and Facebook Pixel.

The majority of these elements are manually introduced to your site through various plugins or themes. This makes it more difficult for a new user to properly eliminate or load them.

Bonus Tips

1. Uninstall Unnecessary Plugins and themes

There are so many plugins that we are using on our website to make it better. But unnecessary plugins slow down our website rapidly. Plugins take to much time to load.

It is very important for a website owner to uninstall and delete unnecessary plugins that he is not using in his website or it’s not needed. There are some default plugins in WordPress that plugin is not necessary for us. Delete unnecessary all things from your website to speed up website.

Themes are also so much heavy to load. WordPress always prefer 2 default theme to install after installing WordPress first time. Delete those themes if you are using another theme.

Delete all themes expect the themes that you are using on time. Try it and see you improve your website speed. Speed up WordPress site rapidly.

2. Choose a fast loading WordPress Theme

The theme is very important for website speed and SEO. Generally, SEO friendly theme is lightweight. There are so many free themes but I personally think the premium theme is better for proper WordPress speed optimization.Explore our WordPress themes collection.

There are so many options in WordPress theme like image slider, different widgets, heavy pop-ups, image gallery, etc. These options might help you to improve to make the website attractive but It will harm your website speed. Always try to ignore those features as much as possible especially when your hosting is not so fast. If you are using VPS or dedicated hosting then it’s completely fine but if you are using shared or managed hosting then you may avoid these features. Trust me it will help you to speed up your website.

3. Install Cache Plugin

Remove cache is very much important for website speed optimization. Cache takes a big place of hosting and take too much time to load. WordPress prefer so many plugins for remove cache. I choose three of them. I personally use this three plugin for my website. Autoptimize, W3 total cache, and Wp Super cache. Not only me more than 1 millions of users use those plugins to improve their website speed. These plugins are easy to use just install them and it will automatically optimize your website cache.

Those plugins improve SEO and user experience on your website. Increase website performance and reduce load time. Download Any two of those plugin for your website.


Another Google ranking factor is the Core Web Vitals measures. Although good scores can help you enhance your rankings, they also let you improve the user experience. Google Core Web Vital is a significant SEO ranking element, but it is more crucial to ensure that your website is optimized for user experience, meaning that it loads as quickly as possible and provides users with the greatest possible perception on both mobile and desktop devices. However if the site still fails the test, ensure that you have the best available hosting with CDN and cache optimization.
