📏 Which Core Web Vitals are measured?

✅ LCP (Largest Contentful Paint) measures how long it takes for the largest visible element (image, video, or text block) on a page to load fully. This indicates how quickly users see and interact with the main content. Google recommends an LCP of 2.5 seconds or less for optimal user experience.

✅ CLS (Cumulative Layout Shift) measures visual stability by tracking unexpected element shifts while loading or interacting. CLS calculates based on size and distance moved by shifting elements. A low CLS (ideally ≤0.1) indicates a stable, user-friendly experience; high CLS scores suggest frustrating layout shifts.

✅ INP (Interaction to Next Paint) evaluates responsiveness by measuring the delay between user interactions (clicks, taps, keyboard input) and visual updates. A good INP (≤200 ms) indicates responsive, smooth user interactions, whereas high values signify sluggish performance.

✅ FCP (First Contentful Paint) measures the time it takes for the first element (text, image, or non-white background) to render, signaling the initial loading process. Google recommends an FCP of 1.8 seconds or less for strong perceived performance.

✅ TTFB (Time to First Byte) tracks how long it takes the browser to receive the first byte of data from the server after requesting the page. Lower TTFB values (ideally <200 ms) reflect better server responsiveness and improved overall performance.
