As you probably may have guessed already, the lower the LCP, the better your score from Google. Google measures LCP as soon as the user starts interacting with the page. For example, scrolling, switching tabs, closing the tab, clicking on a call-to-action, etc.


First Input Delay – FID

FID or First Input Delay is the second metric of Google core web vitals. It calculates the time in milliseconds from when the user starts interacting with your site when the browser or website can respond to its request. In other words, it’s a metric that measures the site’s responsiveness as well as interactivity. You may have seen Total Blocking Time in tools such as GTMetrix and Google Insights. That is the measurement of FID.


Cumulative Layout Shift – CLS

It is measured from the viewport size, which is connected to various elements responsible for moving two or more elements. CLS is scored from zero to any positive number. If your website gets CLS to a zero score, it has no page shifting, and the more score you get, the more page shifting you have on the website, which is an imperfect measurement.
