Core Web Vitals indicators

Largest Contentful Paint (LCP)

Largest Contentful Paint (LCP) measures how long it takes to display the largest visible element of a page's main content. In other words, it measures page load speed. A good LCP score means the page loads quickly and provides a smooth user experience.

First Input Delay (FID)

First Input Delay (FID) measures how long it takes for a page to respond to a user's first interaction, such as clicking a button or filling out a form. A good FID score means the page is responsive and the user can interact with it quickly.

Cumulative Layout Shift (CLS)

Cumulative Layout Shift (CLS) measures the cumulative shift of page elements during loading. A good CLS score means that page elements don't move unexpectedly, providing a stable, uninterrupted user experience.
