What are Core Web Vitals?

Core Web Vitals are a set of metrics developed by Google to measure user experience on the web. They focus on three key aspects: loading, interactivity, and visual stability.

These metrics are crucial for understanding how users perceive the performance of a web page. Loading is measured by the Largest Contentful Paint (LCP), which indicates how quickly the main content of a page is visible. Interactivity is assessed using the First Input Delay (FID), which measures the time it takes for a page to become interactive. Visual stability is evaluated through the Cumulative Layout Shift (CLS), which tracks unexpected layout shifts that affect user experience.

Improving Core Web Vitals can lead to better user engagement and higher search rankings. Websites that perform well on these metrics often see increased visitor satisfaction and retention. Google considers these metrics as part of its ranking algorithm, making them essential for SEO. By optimizing Core Web Vitals, businesses can enhance their online presence and competitiveness.
