The Web Vitals metrics consist of three individual metrics and measure the rendering time of the largest element within the visible area of the page, the time that elapses between user interaction and the browser’s reaction, and the visual stability of a website. Google also has the speed measurement tool, Pagespeed Insights, revised. The tool now shows you the values of the individual metrics as well as the total value calculated from them. The tool also gives you advice on how to achieve better values.
