LCP Test Page

This page intentionally loads a large hero image slowly to trigger poor Largest Contentful Paint (LCP) metrics.

Expected LCP: > 4 seconds (Poor)

Understanding LCP Issues

Largest Contentful Paint (LCP) measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading.

Common causes of poor LCP:

  • Slow server response times
  • Render-blocking JavaScript and CSS
  • Slow resource load times
  • Client-side rendering

This page demonstrates:

  • Large hero image loaded from external source
  • Multiple render-blocking resources
  • Large inline CSS that delays rendering
  • Delayed image loading via JavaScript
