  3. Poor – When your page’s CLS score is above 0.25.

  1. Good – When the largest content element loads in under 2.5 seconds.
  2. Needs Improvement – When the content element takes longer than 2.5 seconds but below 4 seconds to load.
  3. Poor – When the largest content element takes longer than 4 seconds.
