What are Core Web Vitals in PageSpeed Insights?

Core Web Vitals are important performance metrics that Google uses to assess the user experience on websites. These metrics focus on loading speed, interactivity, and visual stability and include:
  1. Largest Contentful Paint (LCP): Measures how long it takes for the main content to load on a page, with an ideal target of under 2.5 seconds.

  2. Interaction to Next Paint (INP): Gauges how quickly a site responds to user actions like clicks or scrolls, with a target of under 200 milliseconds for a smooth user experience.

  3. Cumulative Layout Shift (CLS): Measures visual stability by tracking unexpected layout shifts, with a target score of under 0.1 seconds.

  4. First Contentful Paint (FCP): Tracks the time it takes for the first visible element to appear, aiming for under 1.8 seconds for an optimal experience.

  5. Time to First Byte (TTFB): Measures server response speed, with an ideal target of under 800 milliseconds.

Optimizing for Core Web Vitals is not only about improving Google rankings but also about providing a better experience for users. Meeting these standards can increase engagement, retain visitors, and build trust with users.
