Core Web Vitals
Core Web Vitals are three Google metrics that measure a page’s loading speed, interactivity, and visual stability.
Core Web Vitals at a glance
Core Web Vitals are three metrics Google uses to measure the real user experience of a web page: loading speed (LCP), interactivity (INP), and visual stability (CLS). Together they capture how fast a page feels, how quickly it responds, and whether elements jump around while it loads.
Why Core Web Vitals matter
Google uses Core Web Vitals as a ranking signal, so a slow or unstable page can lose visibility even with great content. They also affect conversions directly: visitors leave pages that take too long to load. Optimized images, lean code, and good hosting are the main ways to keep these metrics in the green.
