Speed & delivery
What makes the page slow, and what the loading experience measures.
Largest Contentful Paint
Target ≤ 2.5s
What this measures
How long until the largest thing on screen, usually the hero image, video or headline block, has finished rendering. It is a proxy for "when did this page feel loaded".
What moves it: Serve the hero image in a modern format at the size it is displayed, preload it, and remove render-blocking CSS and JavaScript ahead of it. A slow server response delays it too, so check TTFB first.
Interaction to Next Paint
Target ≤ 200ms
What this measures
How long the page takes to respond visibly after a tap, click or key press, measured across every interaction, not just the first. High INP is what makes a page feel unresponsive even once it looks ready.
What moves it: Break up long JavaScript tasks so the main thread is free to respond, defer work that is not needed for the interaction, and avoid large re-renders on every event.
Cumulative Layout Shift
Target ≤ 0.1
What this measures
How much visible content jumps around while the page loads. This is what makes someone tap the wrong thing because a banner or image pushed the layout down underneath their finger.
What moves it: Give images and video explicit width and height so the browser reserves the space, reserve room for ads and embeds, and avoid inserting content above what is already on screen.
First Contentful Paint
Target ≤ 1.8s
What this measures
How long until anything at all appears, the first text or image painted. It separates "the page starts slowly" from "the biggest element is slow": a fast FCP with a slow LCP points at the hero, while both slow points at the server.
What moves it: Cut render-blocking CSS and JavaScript in the head, inline the styles needed for the first screen, and improve the server response time.
Real-user response time

Time to first byte
The server took 3003 ms to send the first byte, delaying everything that follows.
How to fix
