Why it matters
They help teams find user-experience problems that can affect usability and page experience.
How to use it
Target LCP at or below 2.5 seconds, INP at or below 200 milliseconds, and CLS at or below 0.1 at the 75th percentile, while diagnosing field and lab data separately.
Limits and interpretation
A perfect Lighthouse score is not the goal, and lab results do not replace real-user field data. Content usefulness and overall experience still matter.
Common mistakes
Chasing a score without fixing the user journey; loading heavy third-party scripts; omitting image dimensions; confusing lab and field metrics.
