What are core web vitals?



Core web vitals are page ranking factors that assist you in improving user experience on your site, enticing Google search engine to rank your page higher on SERP.

There are two types of web vitals such as:

1. Core Web Vitals

  • LCP - largest Contentful Pain
  • FID - First Input delay
  • CLS - Cumulative Layout Shift

2. Non-Core Web Vitals

  • TBT - Total Blocking Time
  • FCP - First Contentful Paint
  • SI - Speed Index
  • TTI - Time To Interactive

Several factors determine how well a website will load for a user. These factors are called Google core web vitals. Largest Contentful Paint(LCP), Cumulative Layout Shift(CLS), and First Input Delay(FID) are the prominent components that will help your website enhance the user experience.

The combination of these three elements will be sent along with HTTPS, intrusive interstitials, and mobile-friendliness to send a signal that Google calls "Page Experience Signal."

An overview of the core web vitals


largest Contentful Paint(LCP)

The largest contentful painting is all about the loading speed of the largest content on your site. LCP makes sure that a user can access your site easily and quickly. It also measures the time it takes for your site's largest content to be rendered on the user's mobile device or a desktop computer.

To get a good LCP score, your site’s largest content, image, or video should occur within 0 to 2.5 seconds. If your site takes from 2.5 to 4 seconds to load the content, it needs to improve its page loading. If it takes longer than 4 seconds, you should optimise your site.

For your information, on your site, if you have a large video content and a simple image, the video content is the LCP, which makes the site significant. Optimizing the content to load faster will keep your site’s user experience healthy.

First Input Delay (FID)

First input delay is the time taken by your site to respond to a user’s action. FID is nothing but the interactivity of your website. This metric is used to monitor the first interaction of a user and the time taken by your site to process it.

To provide a good site experience for your users, FID should be within 100ms. If you find your site’s FID is between 100 ms and 300 ms, it needs to be enhanced in terms of user interactivity. Above 300ms, you need to fix the problems to make sure that your users are happy with interacting on the site.

Don’t you feel annoyed when you click on something and nothing happens or it takes a long time to process?

Cumulative Layout Shift (CLS)

In core web vitals, cumulative layout shift is one of the most important metrics. The CLS provides you with the ability to measure how your website shifts unexpectedly. Optimizing your CLS score will reward your website with a better user experience, which will improve your site's ranking.

For example, you’re reading one of your favourite books online. Suddenly, a pop-up appears out of nowhere, which shifts your e-book down the way. Without doubt, this will be irritating. Especially when you’re reading your favourite book!

A good CLS score is below 0.1. If the CLS score slips between 0.1 and 2.5, you need to improve the site. Above 2.5, you gotta roll your sleeves and jump into the scene, be a hero.

You can use tools like pageInsights or Lighthouse to find the score of core web vitals and to provide optimization ideas.

But one thing you can be sure of is your website content. A content silo is also called a content cluster, which enhances your website's data structure and helps with user experience.

Every silo page of your website should have at least five posts that will help readers dig deeper into the topic that they are looking for.
