First Contentful Paint (FCP)

First Contentful Paint (FCP) is a performance metric that measures the exact time from when a user initiates a page load until the browser renders the first piece of DOM content, such as text, an image, or a background canvas. FCP is a critical indicator of perceived load speed; a fast FCP reassures the user that the page is actively responding, drastically reducing bounce rates. Optimizing FCP requires aggressive technical intervention, including minimizing render-blocking CSS, deferring non-critical JavaScript, and leveraging a Content Delivery Network (CDN) to ensure the server delivers the initial HTML payload instantaneously.

First Contentful Paint is the exact moment the very first piece of text or image appears on a user’s screen after they click a link. If this takes too long, users assume the website is broken and immediately hit the back button.
