Core Web Vitals are a set of specific page experience metrics that Google uses as ranking signals. They consist of Largest Contentful Paint (LCP, measuring load speed), Interaction to Next Paint (INP, measuring responsiveness), and Cumulative Layout Shift (CLS, measuring visual stability). Websites that score well on Core Web Vitals provide better user experiences and are rewarded with ranking advantages. Optimizing for these metrics is a key component of technical SEO.
