TL;DR — Quick Summary
A page 'passes' CWV when all three metrics (LCP ≤ 2.5s, INP ≤ 200ms, CLS ≤ 0.1) meet the 'good' threshold at the 75th percentile of real-user data. Failing even one metric means no ranking boost.
What is Pass / Fail Core Web Vitals?
Pass/Fail Core Web Vitals refers to the binary assessment Google makes for each page based on field data from CrUX. A page passes when all three CWV metrics meet their respective 'good' thresholds at the 75th percentile over a 28-day rolling window. There's no partial credit — failing one metric results in an overall 'fail.'
