What is web core vitals?

Web Core Vitals, a group of three metrics, are not just technical jargon. They are the key to understanding and improving your website’s user experience. By mastering these metrics, you boost your website’s ranking in search results and gain the power to provide a superior user experience. As a website owner, developer, or digital marketer, this knowledge empowers you to take control of your website’s performance and SEO and confidently navigate the digital landscape.

Web Core Vitals, a group of three metrics that evaluate a webpage’s speed, interactivity, and visual stability, are more than just ranking factors for SEO. They are a crucial subset of factors that form part of Google’s ‘page experience’ score, a comprehensive evaluation of your page’s overall user experience. By improving these metrics, you can significantly enhance your website’s ranking in search results and offer a superior user experience, as recognized by Google’s page experience score, thereby increasing your website’s visibility and credibility in the eyes of the most popular search engine.

Main three pillars of Web Core Vitals are:


  1. First input Delay (FID): First Input Delay (FID) is a crucial metric that measures the time it takes for a user’s first interaction with your website to be processed. This text refers to any interactive element that initiates an action, such as a button or link.FID is essential because it reflects your website’s responsiveness to user actions. The lower the FID, the more responsive your website is, leading to a better user experience.
  2. Largest Contentful Paint (LCP): To ensure a good user experience, it is crucial to prioritize a web page’s loading performance. The loading time of a page’s most significant element, like an image or text block, can be measured by Contentful Paint. It is measured when the user begins loading the page and should take no longer than 2.5 seconds to load.
  3. Cumulative layout shift(CLS): CLS measures how much the layout shifts unexpectedly when users view a webpage. A low CLS helps ensure a delightful user experience and should be less than 0.1. It measures how many changes occur when a web page loads and is an essential metric for visual stability. A bad CLS can negatively impact the user experience, such as when a banner appears and pushes all the content under it, causing users to select the wrong product. Bad CLS can be measured from things like the one above. CLS calculates how often unexpected layout changes.

These metrics measure a website’s loading speed and user experience and are increasingly important for SEO. We will discuss it here.
