“Core Web Vitals” are a set of performance metrics defined by Google to measure the user experience on websites. These metrics aim to provide a standardized and objective way of measuring website performance and user experience, and they are considered important factors for ranking and visibility in Google’s search results.
The Core Web Vitals are:
- Largest Contentful Paint (LCP): Measures loading performance, and aims to ensure that the main content of a page is loaded quickly and visibly.
- First Input Delay (FID): Measures interactivity, and aims to ensure that users can interact with a page as soon as possible after it has loaded.
- Cumulative Layout Shift (CLS): Measures visual stability, and aims to ensure that the content on a page does not move or shift around as the page is loading, causing a poor user experience.
The Core Web Vitals are updated periodically by Google, and webmasters and developers can use tools like the Google Search Console, Chrome DevTools, and Lighthouse to monitor and optimize their website performance against these metrics.
