Blog / Core Web Vitals

Core Web Vitals are Google's three field metrics: LCP, INP, and CLS. They measure load speed, responsiveness, and visual stability. Since 2021 they have been a ranking factor. Understanding them is essential for SEO and user experience. Each metric has defined thresholds (good, needs improvement, poor). Google uses the 75th percentile of real-user data from Chrome.
