Core Web Vitals
Google's metrics for loading, interactivity, and visual stability.
Core Web Vitals are a set of Google metrics measuring real-world page experience: Largest Contentful Paint (loading), Interaction to Next Paint (responsiveness), and Cumulative Layout Shift (visual stability). They're a confirmed ranking signal.
Fast, stable pages improve both SEO and conversion. Modern hosted platforms like Framer are built to score well by default, but heavy images and scripts can still hurt.
Key characteristics
- Google's user-centric speed and stability metrics, and a ranking signal.
- LCP measures loading, INP measures responsiveness, CLS measures visual stability.
- Targets: LCP under 2.5s, INP under 200ms, CLS under 0.1.
- Measured on real-user field data, not just lab tests.
Example
A page where the hero image loads in 2 seconds, buttons respond instantly and nothing jumps as it loads passes Core Web Vitals — helping both ranking and conversion.
Frequently asked questions
What are the three Core Web Vitals?
Largest Contentful Paint (LCP) for loading, Interaction to Next Paint (INP) for responsiveness, and Cumulative Layout Shift (CLS) for visual stability. INP replaced First Input Delay in 2024.
Do Core Web Vitals affect SEO?
Yes. They're part of Google's page experience signals and can influence rankings, especially as a tiebreaker between similar pages — and they directly affect user experience and conversion.
