Core web Vitals is solely based on a change in features according to user experience.  It will affect the ranking of websites in search engines.  It is the new ranking parameter introduced by Google. This will ultimately introduce new methods of Search Engine optimization. 

So,  this Core Web Vitals comprise of three main signals which are mentioned below.

LCP, FID and CLS Ranking for WordPress

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

So,  here we will know in detail about all the three new signals introduced by Google under Core Web Vitals.

  1. Largest Contentful Paint ( LCP)  WordPress Speed Optimization 

Many metrics to capture page load experience were introduced in past. None of them is up to the mark. All have cons interrupt in tracking the exact time. Some of them are load, First Contentful Paint (FCP), First meaningful Paint (FMP),  Speed Index (SI). So, after noticing the inconvenience and errors of all the above metrics new metrics will be introduced by Google, which is the Largest Contentful Paint.  

Let Us Know What Is LCP? 

In simple terms, it is the time consumed to load the most relevant element regarding the user search topic on the web page. Don’t get confused with the time consumed to load a web page.  It measures the Loading time. 

Google Metrics Of Right LCP

Ideally, to load the main content of the page it should take less than 2.5 seconds. If time consumed is between 2.5 seconds to 4.0 seconds then it needs improvement. If it is more than 4 secs Google termed it as poor. The colors are coded as Green, Orange, and Red respectively. This will further affect the ranking of your website. 

Fast LCP provides a rich user experience. It will help you to keep the interest alive in User. They won’t leave the page as they can see the main content. 

LCP for WordPress website

We have few tools to measure LCP.  It is divided into two parts.

    • Field tools 
    • Page Speed Insights: As the name suggests it gives you exact insight into the loading speed of your page
    • Chrome User Experience Report: It gives you a user report.  Google helps you to get the data
    • Search Console (Core Web Vitals Report): This gives a report about the page and is specific to point out the area where improvement is required. 
    • Lab Tools
    • Lighthouse: Lighthouse is one of the most useful tools to measure LCP.  It tells you LCP as well as shows you the area where you can improve. It is an automated audit tool. You can install the lighthouse by chrome extension. 
  • Web Page Test: Though the field tool is more reliable and exact as compared to Lab tools. 

Now you have measured the LCP.  If your LCP is coded as Orange or Red Colour you may need to improve your LCP.  It comprises of the following factors.

  • Time consumed by the server to respond
  • The time consumed to  load different resources for example images and videos 
  • The time caused by render-blocking resources
  • The JavaScript bootup time using Client-side Rendering. 

By improving these factors ultimately you will be able to improve the Largest Contentful Paint. This will help you to optimize the speed of your WordPress. It is one of the ways for WordPress website optimization – speed and core web vitals. 

  1. First Input Delay (FID) WordPress Speed Optimization 

Have you clicked on a link present on the page and it took a minute or more to open. Weren’t you bored and annoyed? Google noticed your inconvenience. So Google is going to introduce the First Input Delay signal in 2021.

Let us now understand the First Input Delay in simple terms.

Suppose you clicked on a link or some referrals mentioned on the page. Now, it usually takes time to respond to your click. This is termed as “ interactivity“. Interactivity is the time taken by page to respond to your command.

First Input Delay measures this interaction time.

According to Google, the metrics of FID are given below.

  • If your page takes less than 100 milliseconds to respond to the click of the user.  Google termed it as good. This will not decline your ranking on the search engine. It is coded with green Colour. 
  • If time consumed to respond to the click is between 100 milliseconds to 300 milliseconds, according to Google your FID needs improvement.  It is coded in orange color. 
  • If the time taken is more than 300 ms, your FID is poor. You need to improve your FID. Otherwise, it may decline your ranking. 

If it takes time to respond to the click it may irritate and frustrate a user.  This will cause the user to back off from the website. Google focuses on user–experience. So, to have a good ranking on the search engine you will need to improve FID. 

Key To Measure First Input Display 

FID is measured mainly by field metrics. In Lab, you can use TBT( Total Blocking Time) to measure.  It measures something else but ultimately helps to improve FID. Feild metrics are majorly preferred. 

A factor that affects First Input Delay is given below.

  • Heavy JavaScript Execution: A lengthy JavaScript significantly affects FID.

How To Measure First Input Delay?

The First input delay library is present in chrome which is useful to measure FID. It can be measured from the usual tools as well.

How To Improve FID? 

Since the problem is induced due to heavy JavaScript execution so by optimizing JavaScript you can improve your FID. It will decrease the time consumed to interact with the user command. 

  1. Cumulative Layout Shift (CLS) WordPress Speed Optimization

Google termed it as “visual stability “. Now, what is visual stability?

This may sometimes irritate the user. 

Google is user-centric. Seeing this inconvenience, google introduced CLS. The work is under progress. 

According To Google Metrics CLS should be

  • If you are able to resume reading within 0.1 sec then it is considered good. So, your website should take zeros seconds to adjust. It is best so color codes as green. 
  • If it takes 0.1 to 0.25 seconds it needs improvement.  The color code is orange.
