Frequently Asked Questions

What are Core Web Vitals?

Core Web Vitals are Google's set of specific factors that measure real-world user experience: LCP (loading), CLS (visual stability), and INP (interactivity).

What is a good LCP score?

LCP should be 2.5 seconds or less for a good rating. Between 2.5s–4s needs improvement, and above 4s is poor.

What is a good CLS score?

CLS should be 0.1 or less for a good rating. Between 0.1–0.25 needs improvement, and above 0.25 is poor.

What is INP?

INP (Interaction to Next Paint) measures overall page responsiveness. Good is under 200ms, needs improvement is 200–500ms, and poor is above 500ms.
