What the three metrics measure
LCP measures how quickly the main content loads (aim for under 2.5s). INP measures responsiveness to user input (under 200ms). CLS measures unexpected layout shifts (under 0.1). They are a lightweight ranking factor and, more importantly, directly affect bounce rate and conversions. Test your pages with PageSpeed Insights.
Pro tip
INP replaced FID as a Core Web Vital in 2024. If your tooling still references FID, update it to track Interaction to Next Paint instead.
Key takeaways
Core Web Vitals measure loading, interactivity, and visual stability.
The three metrics are LCP, INP, and CLS.
Targets: LCP under 2.5s, INP under 200ms, CLS under 0.1.
A minor ranking factor, but a major UX and conversion lever.
