Core Web Vitals

Core Web Vitals are a set of metrics that measure the real-world user experience for loading performance, interactivity, and visual stability of the page. They are part of Google’s Page Experience ranking factor, which means that they can have a direct impact on your website’s visibility in search results.

What are the three Core Web Vitals metrics?

  • Largest Contentful Paint (LCP): Measures loading performance and the speed at which the largest content element is displayed on the page.
  • First Input Delay (FID): Measures interactivity and the time it takes for a website to respond to user input.
  • Cumulative Layout Shift (CLS): Measures stability and the amount of unexpected layout shifts that occur on a page.

What do Core Web Vitals do?

Core Web Vitals are designed to provide website owners and developers with a clear understanding of how their website performs in terms of loading speed, interactivity, and visual stability. These metrics are critical to delivering a good user experience on the web.

When a website loads quickly, is responsive to user interactions, and doesn’t have unexpected layout shifts, it provides a better user experience than a site that takes too long to load, is slow to respond, and has frequent layout shifts.

How to improve Core Web Vitals

  • Minifying code: Minifying code removes unnecessary whitespace and comments. This can make the code smaller, which can improve loading speed.
  • Using a caching plugin: A caching plugin can store static copies of your web pages, which can reduce the time it takes for the pages to load.
