Core Web Vitals is one of Google’s new criteria for evaluating and ranking websites, which was introduced in 2020. But what are Core Web Vitals and what factors of the site are examined? As you know, page experience is closely related to user experience and is one of the important factors for Google in the process of ranking a site. This parameter examines the level of user interaction with different pages of a website based on different criteria. This is why developers pay special attention to optimizing and improving the user experience when visiting the site.

But how can we analyze the user experience and identify the strengths and weaknesses of our site? That’s where Core Web Vitals comes in, measuring user experience based on three key metrics. Therefore, using this practical tool will help you to optimize the pages of your site to improve and enhance the user experience.

1. What is the Core Web Vitals?

The Core Web Vitals is a set of Google criteria to check and measure the page experience or the user experience when visiting different pages of a site. These criteria are related to concepts such as page loading speed, responsiveness, and visual stability of the site.

That is, how quickly your webpages are loaded for users and whether your site is displayed well for users on all devices. All these criteria are carefully examined by Google when reviewing and ranking websites.

Due to the high importance of these factors in the ranking, Google has introduced a new indexing factor called the Core Web Vitals. Using this factor, you can check the user experience when visiting your website and optimize it accordingly.

2. Core Web Vitals metrics and improvement methods

Core Web Vitals uses three main and important metrics to measure user experience on a website. Using these metrics, web developers can easily check and measure the user experience of their site and take the necessary measures to optimize it. But what are the criteria to measure Core Web Vitals? The three important criteria of the Core Web Vitals are:

What is Core Web Vitals? How can it be used to improve site performance?

2.1. Largest Contentful Paint

Largest Contentful Paint (LCP) refers to the time it takes to load the main content of a page and display it to the visitor, which will have a direct impact on the user experience and the page view rate.

This metric examines and measures the duration of the user’s click until the content is fully loaded on the screen.

Therefore, the shorter the LCP duration, the faster the contents of a page will be loaded and displayed, which will improve the user experience and provide faster access to the required information.

According to Google standards, LCP duration is ideally between 2.5 and 4 seconds, and if this value increases, you should think about improving and reducing the loading time of your website. You can do the following to improve your site’s LCP:

  • Remove all unnecessary codes
  • Using a more powerful hosting service
  • Activating Lazy Loading
  • Reducing the amount of CCS
  • Using a CDN

2.2. First Input Delay

First Input Delay (FID) is another important factor in the Core Web Vitals, which examines the duration and manner of user interaction with the website. User interaction with the page means performing actions such as clicking on a link, choosing an option from the site menu, registering, etc.

In this situation, FID will check and measure the time it takes for the website to respond appropriately to user actions. Ideally, the FID of a site should be less than 100 milliseconds so that you can create a good experience for users and thereby improve your site’s ranking.

To improve FID and reduce response time to user requests, you can do the following:

  • Reducing the number of JavaScripts on the site
  • Remove redundant and unnecessary scripts
  • Using the browser cache

2.3. Cumulative Layout Shift

Cumulative Layout Shift (CLS) is also the last factor of the three criteria of the core web vitals, which examines the level of image and visual stability of the website. In other words, if the elements of your website are moved after the site is loaded, then the CLS of your site will be high, which will harm its ranking.

In some websites, the layout and arrangement of some elements change after loading the page or its elements are moved. LCP examines the level of difficulty and user involvement with unexpected changes in site elements, which should ideally be less than 0.1. To minimize the LCP of your website, you can use the following methods:

  • Use all the media on the website, including videos, images, infographics, GIFs, etc., in their
    standard size so that the browser knows exactly what space each element needs. In this case, you will not see the elements change and move when the site loads.
  • Display the site’s advertising messages in a predetermined space so that they are not suddenly displayed on the screen; Because in this case, they will cause interference in the display of content and other visual elements of the site.
  • Display new user interface elements such as clickable options or pop-ups at the bottom of the site so that they do not move the contents and other elements of the site.

3. Why did Google create Core Web Vitals?

The question you may have now is why Google created Core Web Vitals. Why did Google include it in its list of important ranking factors? To rank and determine the position of a website on the search results page, Google pays attention to more than 200 different criteria and examines them carefully. Some of these criteria include the quality of the content, the responsiveness of the site, the number of backlinks, the loading speed of the site, the use of appropriate keywords, etc., each of which plays an important role in determining the site’s ranking in Google. Meanwhile, page experience or user experience when visiting the site are other important factors that Google pays special attention to for ranking the site. Because the first goal of all websites is to meet the needs of users and provide them with the information they need.

For this reason, you should design your website in such a way that you can respond to the needs of users and create a good experience for them. When Google recognizes that the contents of a website are useful and valuable for users, it considers this positive point when ranking the site and improves its position on the search results page.

But how can Google measure user satisfaction or page experience? The core web vitals is a criterion through which Google can easily determine the page experience of a site using three main criteria, i.e. CLS, FID, and LCP, and based on the obtained results, determine its rank in the search results.

Therefore, the measurement of user experience with the core web vitals is currently considered one of the most important Google criteria for ranking websites and plays a decisive role in this process.

For this reason, it is very important to improve the page experience and measure how the user interacts with the pages of a site; Because Google pays special attention to this important parameter when ranking.
