  • Needs Improvement : 2.5s – 4s 

  • Poor : More than 4s

FID –  First Input Delay (FID) measures a user’s first impression of your site’s interactivity and responsiveness, the good score of FID is 100 milliseconds or less.

  • Good : <= 100ms
  • Needs improvement : > 100ms and <= 300ms
  • Poor : > 300ms

CLS – Cumulative Layout Shift (CLS) measures how stable your page layout is during the entire lifecycle. It measures the visual stability of a website.

  • Good : <= 0.1
  • Needs improvement : > 0.1 <= 0.25
