Core Web Vitals

Core Web Vitals are Google's real-user speed metrics: how fast the main content appears (LCP), how quickly the page responds to interaction (INP), and how much the layout jumps around while loading (CLS). They're measured from actual visitors and used in ranking, so they translate engineering quality directly into search visibility. Slow, janky pages lose both rankings and the visitors who do arrive.
