[Rex Maughan]

WordPress Core Web Vitals are performance metrics that measure the speed, interactivity, and stability of your WordPress website.


It affects both user experience and Google search rankings.



1. Largest Contentful Paint (LCP)

Measures the time it takes for the main content, such as an image or text block, to appear.


2. First Input Delay (FID)

Measures the delay from when a user first interacts, such as clicking or tapping, to when the site responds.


3. Cumulative Layout Shift (CLS)

Measures any unexpected layout shifts that occur, such as buttons moving around, while the page is loading.
