Core Metrics

• LCP for loading performance
• CLS for visual stability
• INP for responsiveness
• FCP for first content paint
• TTFB for server response speed

Notes

• Enable Web Vitals in project settings to receive vitals data.
• cookieless mode is suitable for privacy-focused deployments.
• Start with default sampling and tune only if traffic is very high.
