Google Core Web Vitals
Core Web Vitals are a standardized set of real-world user experience metrics defined by Google that measure page load performance (LCP), visual layout stability (CLS), and interactive responsiveness (INP).
Technical Explanation & Importance
Google uses Core Web Vitals as a direct ranking signal for mobile and desktop search results. The three core thresholds are: Largest Contentful Paint under 2.5s, Cumulative Layout Shift under 0.1, and Interaction to Next Paint under 200ms. All Wefik themes and templates are designed to pass these metrics out of the box.
Key Engineering Takeaway
Understanding Google Core Web Vitals is critical for engineering production-grade, bloat-free websites. All Wefik themes, plugins, and templates implement these standards natively.
