First Contentful Paint (FCP)

First Contentful Paint (FCP) is a measure of when the browser renders its first DOM content, providing user feedback that the page is loading. Completing the first Contentful paint answers the question "Is anything happening?"

The First Contentful Paint timestamp indicates when the browser first rendered any text, image (including background images), video, canvas that had been drawn into, or non-empty SVG. This excludes any iframe content, but includes text with pending webfonts. This is the first time users could start consuming page content.
