What is Core Web Vitals?

Table of Contents

Core web vitals is considered as a set of metrics that helps Google to measure user experience on your web page. These metrics relate to a page’s interactivity, load time, and visual stability of content as it loads. If your website performs well based on these parameters, Google will improve the visibility of your website.

By making core web vitals a factor of ranking, the search engine is encouraging developers to focus on UX.

Core web vitals address issues related to user experience by generating a metric for three primary areas of UX, including:

Visual stability of a page
Ease of interaction
Page loading performance

Having a solid user interface and a good core web vitals score can help increase the conversion rate.

If your website doesn’t have a passing score on various core web vitals metrics, this can signify that your site has poor UX. It can also affect your online ranking, conversion rate, and revenue.

#1 Largest contentful paint (LCP)

LCP is an essential and user-centric metric of core web vitals. Admin utilizes large contentful paint to access user experience. This metric helps to measure the loading performance of the website.

LCP shows the render time of the largest text block or image visible within the viewport. In simple words, it measures how long it takes for big elements to become visible. The aspects of LCP can differ between desktop and mobile.

Your site should have LCP of 2.5 seconds or less to offer a good user experience. Core web vitals developers will ensure that all images are served in next-generation format and are compressed to improve the score. The developer will help you to solve the LCP issue by scaling images and defining image sizes.

Core web vitals developer will reduce the large contentful paint by:

Removing Unused JavaScript
Removing Unused CSS
Minifying CSS and JS Files
Reducing Server Response Time
Improving the Time to First Byte
Using a CDN
Using Preload for Critical Assets
Establishing Third-party Connections Early
Optimizing Your Images
Compressing Text Files

#2 The first input delay (FID)

FID is a metric that measures a user’s first impression of your website’s responsiveness and interactivity. The first input delay measures the user’s first interaction with a web page (for instance, when the user uses JavaScript-powered or custom control, taps a button, or clicks on a link).

This metric only focuses on input events from discrete actions such as key presses, taps, and clicks. Other interactions like zooming and scrolling are continuous actions and have various performance constraints.

Your webpage should achieve the FID of 100 milliseconds or less to offer a good user experience. In order to optimize your webpage’s FID, core web vitals developer will take the following steps:

Optimize your page for interaction readiness
Reduce JavaScript execution time
Break up long tasks
Reduce the impact of third party code
Decrease main thread work

Developers may also use Lighthouse performance audit and fix the issues the audit suggests. They can also help you to reduce the first input delay by improving the execution of javaScript.

#3 Cumulative layout shift (CLS)

CLS is a core web vitals metric that measures the visual stability of your webpage. Have you ever experienced something unexpectedly changing on the webpage? Sometimes images and texts move without any notification.

Most of the time, these types of conditions are just annoying and can cause real damage. Unexpected movements of elements on a webpage generally occur when the resources are added asynchronously. CLS metric helps admin to find this issue by determining how often it’s happening for real users

The following factors can cause a low CLS score:

Videos and images without dimensions
Dynamically injected content (for example, animations)
Web font causing a flash of invisible text (FOIT) or flash of unstyled text (FOUT)
Iframes, embeds, and ads without dimensions
Actions waiting for a network response

A poor CLS score can hugely affect the user experience and decrease the visibility of your website on search engines. Your webpage should maintain a CLS of 0.1 or less to offer a good user experience. If the visual stability of your webpage is not good, you can hire core web vitals developer.

Your developer will help you to fix a cumulative layout shift by:

Including height and width size attributes in video and image elements
Managing size and space for Ad slots
Preloading fonts and optimizing them
Managing dynamic content
Managing space for Iframes and embeds
Using CSS for animations

Your developer will help you to pass your core web vitals assessment by improving these metrics. Having a good core web vitals score means your page offers a positive page experience, and your page will be rewarded for having strong visual stability, interactivity, and fast loading time.
