Good Largest Contentful Paint

Measures how fast a page's main content loads. To provide a good user experience, the LCP should be 2.5 seconds or less.

Good Cumulative Layout Shift

Measures how much and how far content unexpectedly moves on a page. To provide a good user experience, sites should maintain a CLS score of 0.1 or less for at least 75% of page visits.

Good First Contentful Paint

Measures initial loading speed. To provide a good user experience, the FCP should be 1.8 seconds or less.

Good Time To First Byte

Measures the time between the request for a resource and when the first byte of a response begins to arrive. A good TTFB is less than or equal to 800ms.

Good Interaction to Next Paint

Measures overall page responsiveness to user actions. To provide a good user experience, the INP should be 200ms or less.
