First Contentful Paint
First Contentful Paint (FCP) is an important performance metric used to measure the time it takes for a web page's primary content to render for a user. This metric measures the time from when the user first requests a page to when any part of the page's content (text, images, etc.) appears on the user's screen. This is an important metric for understanding the overall performance of a website, as it gives a general indication of how quickly the page is loading and how well the browser is responding.
