Core Web Vitals

/kɔːr wɛb ˈvaɪ.təlz/ noun

Google's set of metrics measuring real-world user experience on a webpage — covering loading performance (LCP), interactivity (INP), and visual stability (CLS). Core Web Vitals are a confirmed Google ranking factor and also influence AI crawler efficiency — pages with poor vitals are crawled less frequently and indexed more slowly.
