The site experience is built on how users perceive a webpage beyond its content; this holds for both mobile and desktop services.

Core Web Vitals: Quick view

A set of metrics that contribute to the web page’s overall user experience based on Google’s algorithms are Core Web Vitals. In a holistic sense, these metrics are used to measure user experience for the following factors:

• Loading performance
• Interactivity
• Visual stability
• Mobile-friendliness
• HTTPS
• Intrusive Interstitial Guidelines

The page speed and user interaction are measured based on three components: LCP or largest contentful paint, first input delay, and CLS or Cumulative Layout Shift.

Simply put, these factors play a crucial role in maintaining a good “page experience score” or “site overall UX” measured by Google.

To find your site’s Core Web Vitals data, you can go to your Google Search Console account and the “enhancements” section.

Breaking Down The Components of Core Web Vitals

At present, there are over 200 ranking factors that contribute to the site ranking; Core Web Vitals is one of them that may boost the site’s visibility once they meet the requirements optimally. This idea suggests how important it is to consider strengthening Core Web Vitals.

LCP or Largest Contentful Paint

It is the largest visible element on the viewpoint, under which the element can either be a featured image or an H1 tag. It is possible for this element could be <img>, <image> inside an <svg>, image inside a <video>,

background image loaded with the URL () function or blocks of text.

Ways to Optimize LCP

A quick look at PageSpeed Insights can address the issues that must be catered to. Here are ways to optimize it.

• Reduce file sizes for the pages to load faster.
• Adopt a Content Delivery Network when you serve a large geographical area.
• Use the same server.
• Cache every resource possible.
• Prioritize how resources will get loaded in the critical rendering path.

CLS or Cumulative Layout Shift

It is a metric that gauges how elements move around a site and the stability of a page layout. Content size and the distance it has to travel determines the CLS. Many causes lead to CLS, like images submitted without dimensions, content injected with JavaScript, and more.

Ways to Optimize CLS

• Reserve required spaces for images to prevent further shifts.
• Get the font to the screen as fast as possible.
• Reserve good space for content if there are any changes to insert content above the existing content dynamically.

FID or First Input Delay

It refers to the time gap when a user interacts with your page and his reaction time on the page, exclusive of actions like scrolling or zooming.

Ways to Optimize FID

• While using the JavaScript framework, use prerendering or SSR to move the burden from the browser to the server.
• Alternatively, you can break up the JavaScript for a shorter run time.
• Another option is to move some of the JavaScript to a service worker.

We hope this post brought you a wholesome idea about Core Web Vitals and its components to enhance your site experience from a user’s perspective.
