What is First Contentful Paint (FCP)?

First Contentful Paint (FCP) は、ユーザーがリクエストした後、ブラウザーが Web ページの最初に表示される要素を表示するまでにかかる時間です。 

The element could be a text, image, or background image. It could also be a <svg> or non-white <canvas> element. 

The First Contentful Paint is one of the metrics used to measure the speed of a webpage. Other metrics include Largest Contentful Paint (LCP) and Time to First Byte (TTFB). That said, Google recommends you keep your First Contentful Paint below 1.8 seconds.
