Core Web Vitals are a critical component of Google’s Page Experience update, introduced in 2021 to enhance user satisfaction by focusing on a website’s performance and interactivity. These vitals consist of three key metrics: Largest Contentful Paint (LCP), which measures the loading speed of the largest visible element; First Input Delay (FID), which assesses how responsive a webpage is to user interactions like clicks or taps; and Cumulative Layout Shift (CLS), which evaluates the visual stability of a page by tracking unexpected shifts in layout during loading. Optimizing these metrics can improve website performance, affecting both user experience and search engine rankings, as they directly influence how users perceive your site’s performance. Google’s emphasis on Core Web Vitals encourages site owners to focus on faster, more responsive, and stable websites, contributing to a smoother overall experience.
