core web vitals

Google search console updated their one term ‘speed experimental’ with the ‘core web vitals’ in May 2020. The search console has updated it under the enhancement tab, to show the data that matter for the website’s URLs speed. 

The core web vitals report shows the status of the website’s URLs performance, divided into device types. In this report, the device type either may be desktop or mobile. The ultimate goal for the Core Web Vitals report is to fix the poor URLs problems and enhance the user experience on your website

If your website or property is new on the search console, you might see a page showing “no data available”. Sometimes you might see the data available for the desktop but no data for the mobile devices, or vice versa. 

It is because of the Chrome UX (CrUX) report did not find enough information for those types of devices (Generally happens with new websites). 

As the name suggests it provides the core data that is important for the user experience on the web (website). It uses three main metrics to describe the report, Largest contentful paint (LCP), First input delay (FID), and Cumulative layout shift (CLS).

 

What is Core Web Vitals

Core web vitals in the google search console replaced the speed experimental report to fix the poor user experience. It shows the data taken from the CrUX report. CrUX report gathers the relevant information of the actual users visiting the website URL.  

The Core Web Vitals describes the CrUX report related to the performance times of the specific URL visitors. It categorized the status of the URL for the users or visitors and shows the report in search console property.

There are three categories for two devices (mobile and desktop):

  1. Poor URLs
  2. URLs need improvement
  3. Good URLs

The reports are showing in the graphs with the color-coded. The poor URLs are in the red-colored, the URLs that need improvements are in the orange color, whereas the good URLs are green. 

 

What affects the Core Web Vitals

According to the google search console, three metrics are the most important for improving the user experience on any website. 

  1. Largest contentful paint (LCP) 
  2. First input delay (FID)
  3. Cumulative layout shift (CLS)

Here in this article, we have mentioned how these three metrics are useful for improving the user experience and how it can affect your website. 

 

Largest contentful paint (LCP)

The largest contentful paint is the time taken for the largest content visible on the website. Here the largest content may be a video, image with high pixel quality, or large text block content.

For speed improvement and better user experience, Google has decided the following boundaries:

 

 

Good

Need Improvement

Poor

LCP

<2.5 sec

≤4 sec

>4 sec

 

First input delay (FID)

The first input delay is the time taken between when users click on the link (URL) to when the browser responds. This is the time when a page becomes interactive to the user. So FID plays a vital role in improving the website speed and user experience.

Though it does not take too much time. But the first input delay can improve the bounce rate and hence website performance. 

The boundaries for FID are given in the below table:

 

Good

Need Improvement

Poor

FID

<100 ms

≤300 ms

>300 ms

 

Cumulative layout shift (CLS)

The cumulative layout shift shows the data for how much a page element has shifted during loading. It has a region from 0 to 1. Zero means no shifting, whereas one means most shifting. When the elements of any page shift, it may create a bad user experience. 

The boundaries for CLS are given in the below table:

 

Good

Need Improvement

Poor

CLS

<0.1 

≤0.25 

>0.25

 

How to improve the Core Web Vital

You can usually see a drastic change in your website traffic, either it may be increase or decrease. The core web vitals are dealt with the user experience and are showing the data of the URLs that can affect the website traffic.
