LCP — loading
Largest Contentful Paint measures main-content loading. Good: 2.5 seconds or less at the 75th percentile.
Core Web Vitals
Googles reale Messwerte für Ladegeschwindigkeit, Reaktionsfähigkeit und visuelle Stabilität.
Einfach erklärt
Core Web Vitals measure loading, responsiveness, and layout stability using real-user data when enough is available.
Lab tests help diagnose issues; field data reflects real visits. These metrics cannot guarantee rankings or overall quality.
Die Grundlage
What matters in Core Web Vitals
INP — responsiveness
Interaction to Next Paint measures responsiveness. Good: 200 milliseconds or less at the 75th percentile.

Wie wir es praktisch umsetzen
We use these measures to reduce waiting and keep pages responsive and stable.
Deliver the important content early
Use server rendering, caching, optimised images, and deliberate loading priorities.
Keep interactions responsive
Limit JavaScript and long tasks so controls respond quickly.
Reserve visual space
Reserve media dimensions and manage font loading to reduce layout shifts.
Measure lab and field data
Use lab tests to diagnose issues and field data to understand real visits.
Eine nützliche Grenze
Wichtige Grenzen
- Core Web Vitals are not the same thing as a Lighthouse performance score.
- Passing the thresholds does not guarantee rankings, conversions, or a satisfying overall experience.
- A single local test cannot represent the range of real devices, networks, pages, and visitors.
Ein konkretes Beispiel
A stable service landing page
A service page loads its main content early, reserves image space, and responds quickly. Field data checks the experience of real visitors.
