First Contentful Paint
First Contentful Paint (FCP) measures the time from navigation to the time when the browser renders the first bit of content from the DOM. This is an important milestone for users because it provides feedback that the page is actually loading.
To speed up First Contentful Paint, speed up the download time of resources or do less work that blocks the browser from rendering DOM content.
