LCP: Largest Contentful Paint
How long until the main content (usually the hero image or headline) appears. Good is 2.5 seconds or less. Common fixes: compress and resize the hero image, use modern image formats, and remove heavy sliders.
INP: Interaction to Next Paint
How quickly the page reacts when someone taps or clicks. Good is 200 milliseconds or less. Common fixes: fewer third-party scripts, chat widgets that load late, lighter page builders.
CLS: Cumulative Layout Shift
How much the page jumps around while loading. Good is 0.1 or less. Common fixes: set image width and height, reserve space for banners and embeds, avoid late-loading fonts that change size.
