First Contentful Paint
What is the First Contentful Paint?
First Contentful Paint (FCP) is one of the many metrics tracked by the Performance Scan on both desktop and mobile. Each metric captures a different aspect of your application's performance.
The resulting FCP is shown in milliseconds:
The FCP metric measures how long it takes for the browser to render the first piece of DOM content after a user navigates to the scanned page.
<canvas> elements, and SVGs are also considered DOM content; anything inside an iframe isn't included.
One issue that's particularly important for FCP is font load time. Check out this post for ways to speed up your font loads.
