Core Web Vitals (CWV) are part of Google’s page experience ranking signals. Webflow’s built-in performance optimizations help improve CWV metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). You can further optimize these by reducing file sizes, using a CDN, and ensuring your site is mobile-friendly. A report from Backlinko found that websites with better Core Web Vitals saw a significant boost in rankings.
