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.
