Core Web Vitals are a set of performance metrics that measure the speed and responsiveness of a website. They were introduced by Google in 2020 to help website owners understand and improve the user experience of their sites. The three Core Web Vitals are:
- Largest Contentful Paint (LCP): measures the time it takes for the main content of a page to load and become visible to the user.
- First Input Delay (FID): measures the time it takes for a page to become interactive, i.e., for the user to be able to interact with it.
- Cumulative Layout Shift (CLS): measures the stability of a page, i.e., how much the content shifts around as it loads.
To improve the Core Web Vitals of a website, you can try the following:
- Optimize images and other large files by compressing them and using modern formats like WebP.
- Minimize the use of third-party scripts and plugins, as they can slow down the loading of a page.
- Use a content delivery network (CDN) to serve static assets, as it can reduce the loading time of a page.
- Enable caching to store commonly used resources in the user’s browser, reducing the need to download them every time the user visits the site.
- Use lazy loading to only load content as the user scrolls down the page, rather than all at once.
- Use a tool like Lighthouse, which is a part of the Chrome DevTools, to analyze the performance of your website and identify areas for improvement.
