Core Web Vitals are a set of metrics that measure the performance of your website pages.

What are Core Web Vitals? 

Core Web Vitals are a set of three key indicators that measure the user experience on websites. They are load time, interactivity, and stability. 

The amount of time it takes for a page to load is referred to as load time. The speed with which a page responds to user input is referred to as interactivity. The frequency with which a page experiences unexpected changes, such as sudden layout shifts, is referred to as its stability.

You can optimize your website for Core Web Vitals by improving your site’s performance and making sure your pages are stable and responsive. You can use tools like Google PageSpeed Insights to test your website’s performance and get tips on how to improve it.

How to Optimize the Core Web Vitals of Your Website

There are three key factors to consider when optimizing your website’s core web vitals: loading, interactivity, and visual stability.

Loading times are critical for user experience. If your website takes too long to load, users will likely leave before they even have a chance to see your content. There are a few ways to improve loading times:

  • Reduce the size of your pages 
  • Minimize HTTP requests 
  • Enable browser caching 
  • Use a content delivery network (CDN)

Interactivity is important for keeping users engaged with your content. If your pages are slow to respond to input, users will likely get frustrated and go elsewhere. There are a few ways to improve interactivity:

  • Eliminate JavaScript that is not essential to the page’s functionality 
  • Load JavaScript asynchronously or defer it until after the page has loaded – Optimize CSS so that the browser can render the page more quickly.

Visual stability is important for creating a smooth user experience. If elements on your page jump around or shift unexpectedly, users will likely get dizzy or disoriented and leave. There are a few ways to improve visual stability:  

  • Avoid animating elements that are not visible on the screen
  • Use hardware-accelerated animations
  • Animate elements using CSS transitions instead of JavaScript

The Different Types of Web Vitals

There are three types of Web Vitals:

  • Largest Contentful Paint (LCP): This metric measures how long it takes for the largest element on your page to load. The largest element could be an image, a video, or even a block of text.
  • First Input Delay (FID): This metric measures how long it takes for your page to become interactive. Once the largest content element has loaded, FID measures the time it takes until users can start using your page.
  • Cumulative Layout Shift (CLS): This metric measures visual stability. CLS looks at how many elements on your page move around while loading and during user interactions such as clicking or scrolling.

You can use Google’s PageSpeed Insights tool to measure your website’s Core Web Vitals. Just enter your URL and Google will give you a report with your website’s LCP, FID, and CLS scores.
