Do you know what core web vital is?

Core web vital is an upcoming Google ranking algorithm that analyzes your page speed and has been activated in a separate section of Google Webmaster from May 2021. It is December 2021, we haven't seen a major effect from the algorithms but it can be one of your bad dreams if this has been rolling out.

What would be our natural reaction, if we hear that Google is updating a new Google ranking factors algorithm?

Most likely, 90% of us (who owned websites) will start to panic about what will happen next?

What will happen if all the keywords go down?

Will the company website suffer due to the new algorithm?

That is not true! or MAYBE!!!  that’s right.

The upcoming Google ranking system is going to boost the user experience, which will help both companies and their customers. Perhaps, we take it differently. Page speed is one thing that does not matter how well you optimize your website page but also matters on other things that we think Google wants us to invest in. 

Do you know why Google is updating its ranking algorithm?

It’s because Google’s focus is the on-page experience of the page.

Google algorithm update would prefer the website pages having these features:

  • Mobile friendly because most of the users access websites from their mobile devices.

  • Relevant content with creativity and uniqueness.

  • Safe browsing options for protecting users.

  • HTTPS-security or SSL-certified websites for avoiding security reasons. It tends to be said that Google will be crawling web pages in http2 protocols. 


A collection of basic variables that Google finds essential in the overall user experience of a website is known as core web vitals. It is related to responsiveness, speed, and all those factors that help to provide a good user experience.

The three Core Web Vitals according to Google update regarding 2021 include:

  • Largest Contentful Paint (LCP)
  • First Input Delay (FID)
  • Cumulative Layout Shift (CLS)

These Core Web Vitals will be added to Google page experience ranking according to the latest Google update (page performance). Therefore, if you want success for a long time & to make your website successful on web optimization, user experience is important. Hint: If you have a shared server that has a server response time really slow should think of moving to VPS with at least 4 GB Server Ram. 

Core web vitals play the role to increase the opportunities to improve the experience of your site. So all these page optimizations mentioned below is good but eventually hosting will play the role. 

‘To get the best response, you need to give the best user experience’

1. Largest Contentful Paint (LCP)

The largest contentful paint (LCP) is the first core strategy mentioned by Google's new update.

It refers to the pictures and videos that take the longest time to load a page. 

Google has mentioned that the ideal time for page loading would be 2.5 seconds. During this period, the site that would load the page without any delay would be preferred by Google. 

4 or more than 4 seconds will be considered low performance & it will impact your ranking starting from May 2021 (as mentioned by Google). The relation of the largest contentful paint (LCP) is from page load speed.

Reasons for poor Largest Contentful Paint (LCP)

There are some reasons which cause more loading time or LCP are mentioned below:

  • First of all, sluggish response times of servers cause slow loading of website visual elements.
  • The other reasons that cause poor LCP are JavaScript and CSS Render-Blocking, heavy resources, & rendering on the client’s end.

How to maintain a good LCP ( Largest Contentful Paint)

Here are the solutions to the problems that increase your page loading time. Reduce the Largest LCP by:

Server optimization, activating CDN, images optimization, assets optimization, reducing critical Javascript, and minifying CSS, cache your HTML, & preloading of your important assets.

2. First Input Delay (FID):

First Input Delay (FID) is the second core strategy mentioned in the Google algorithm update 2020. If your website page can not interact with users, it would be a great alert for you. 

Yes, that is what it means!

First Input Delay (FID) refers to the interaction of your site with your users. It will calculate the time users experience when they interact with your page for the first time. The purpose of FID is to provide a user-friendly experience. Therefore, your First Input Delay should be less than 100 milliseconds (ms) if you want to offer a better experience. 

Reasons for poor First Input Delay (FID)

The main reason to cause bad FID is the detail & heavy execution of Javascript. It prevents the browser from running event listening (it means the response time of the browser makes delay towards user requests)

That is why more usage of Javascript (by your page) can cause more First Input Delay. 

How to maintain a good FID (First Input Delay)

The solutions that will help you to minimize your First Input Delay are:

  • Minify Javascript (that is unused),
  • utilization of web workers, 
  • removal of non-critical third-party scripts, and 
  • usage of the browser cache.

Do you get this factor? 


Then you are good to go for the next step.

3. Cumulative Layout Shift (CLS):

Now, here comes the third factor that is Cumulative Layout Shift (CLS) in Google algorithm changes. It is considered an important factor for web page efficiency. It refers to calculating the page stability & the main focus is the visual stability of the page. Random website design changes and location can cause trouble. It can mislead the users that would result in a negative impression and frustration for the clients. That’s why Google prefers CLS correction.

Most of us experience a problem when the website is working slowly or has any layout problem. When we click on another option, it ends up on another page.

Yes, you remember that, right?

Any layout problem can trigger changes (in position) during page loading. It can affect the calculation of the Accumulated Layout Transfer. It is mentioned in the Google search update that less than 0.1 would be called the optimal measurement of the CLS.

Reasons of Cumulative Layout Shift (CLS)

The problems that cause bad layout shifting are:

How to maintain CLS (Cumulative Layout Shift)

Here are the points and tips that will help you in fixing cumulative layout shift:

  • Images, videos, and ads should always have the required height & width values.
  • Usage of proper fonts & dimensions setting of ads and embeds.
  • Optimization of HTTP response & improve elements synchronization.
  • Handling of dynamically injected content.

Do you know what are the benefits of a website that gives a better user experience?

The web pages with good user experience help in:

  • Increasing web page traffic
  • Reducing the bounce rates of your website
  • Increasing your conversion rate & revenue
  • It helps to boost your business sales & increases efficiency.

That is why the new Google search update is bringing changes towards a better website experience.


Google has provided a Google SERP update that will be implemented from May 2021. The focus of this Google core update would be Core Web Vital. But it doesn’t mean that content relevancy & keyword search will not matter anymore. Multiple factors can affect your website and page performance. The core vitals that are responsible for these issues are LCP, FID, & CLS. 

But there is nothing to worry about if you are already giving the best user experience from your sites. So, according to the latest google algorithm update, maintain the page quality. In case of any irregularity, check out solutions and implement them. 

Are you all done with information collection?

Best of luck, now you are good to go!
