Google uses Core Web Vitals as a ranking factor. This guide covers core web vitals monitoring wordpress and how Opti-Behavior Pro tracks all 5 vitals in your dashboard.

What Are Core Web Vitals?

Performance metrics by Google. Ranking factor since 2021. Five key metrics every WordPress site must monitor.

LCP (Largest Contentful Paint)

LCP measures loading. Time for largest element to render. Good: under 2.5s. Poor: over 4s.

CLS (Cumulative Layout Shift)

CLS measures visual stability. Content shifts during loading. Good: under 0.1. Poor: over 0.25.

INP (Interaction to Next Paint)

INP measures responsiveness. Replaced FID March 2024. Good: under 200ms. Poor: over 500ms.

FID and FCP

FID: first interaction delay (good: under 100ms). FCP: first paint time (good: under 1.8s).
