Core Web Vitals

Core Web Vitals are three measurements Google uses to describe how a page feels to a real visitor, not just how fast it loads. They track how quickly the main content appears, how stable the layout stays as it loads, and how promptly the page responds when you tap or click. When they're poor, people notice it directly: shifting buttons, delayed taps, a page that feels janky. On course and publishing sites that broken feeling pulls people out of the flow and costs you engagement.
