What is Google Core Web Vitals ?

Google Core Web Vitals are a set of specific factors that Google considers important for delivering a good user experience on the web. These metrics focus on three key aspects of page performance:

Basic Core Web Vitals Metrics:

1. Largest Contentful Paint (LCP):

   • Definition: Measures loading performance. It marks the point in the page load timeline when the largest text block or image is rendered on the screen.
   • Goal: An LCP of 2.5 seconds or faster is considered good.

2. First Input Delay (FID):

   • Definition: Measures interactivity. It quantifies the time it takes for a user to interact with a page (e.g., clicking a link or button) until the browser responds.
   • Goal: An FID of 100 milliseconds or less is considered good.

3. Cumulative Layout Shift (CLS):

   • Definition: Measures visual stability. It assesses how much the page layout shifts during the loading process, which can lead to poor user experience.
   • Goal: A CLS score of 0.1 or less is considered good.
