Use resource hints for faster loading

Resource hints let the browser start fetching critical assets earlier—improving LCP by 100-300ms on average.

Quick Reference

  • Use preload for critical above-the-fold resources (fonts, hero images)
  • Use preconnect for third-party origins (CDNs, APIs, analytics)
  • Use prefetch for resources likely needed on next navigation
  • Use dns-prefetch as a lightweight alternative to preconnect

Check

Analyze resource hints on this page and verify critical resources use preload/preconnect for optimal loading.

Fix

Add appropriate resource hints (preload, prefetch, preconnect) for critical assets to improve loading performance.
