CrUX FCP(s)

The CrUX FCP (First Contentful Paint) metric measures how quickly the first visible content appears on a webpage. It is retrieved via the CrUX API for a specific origin, with the formFactor based on the user agent used in the crawl. For example, if a mobile user agent is used, the FCP data will reflect the "phone" formFactor, showing how fast content loads on mobile devices, helping improve load performance.
