Core Web Vitals are a set of specific website performance metrics that are considered critical to user experience. These metrics are used by Google to evaluate the loading speed, interactivity, and visual stability of web pages. The Core Web Vitals consist of the following three key metrics:
- Largest Contentful Paint (LCP): This measures the time it takes for the largest element on a page (such as an image or video) to load and become visible to the user.
- First Input Delay (FID): This measures the time between when a user first interacts with a page (such as clicking a button) and when the page actually responds to that interaction.
- Cumulative Layout Shift (CLS): This measures the amount of unexpected layout shifts that occur during the loading process, which can cause elements on the page to move around or resize unexpectedly.
Google considers Core Web Vitals to be important factors in determining a website’s overall ranking in search results, as they are closely tied to user satisfaction and engagement. As a result, website owners and developers are encouraged to optimize their sites for these metrics in order to provide a better user experience and improve their search visibility.
