Optimize third-party script loading

Third-party scripts are the #1 cause of slow websites—unoptimized loading can add 2-5 seconds to your page load time.

Quick Reference

• Use async for independent scripts (analytics, ads)
• Use defer for DOM-dependent scripts (chat widgets, social)
• Lazy-load non-critical scripts after page load
• Consider self-hosting critical third-party scripts

Check

Analyze third-party scripts on this page to ensure they use async/defer and don't block rendering.

Fix

Add async or defer attributes to third-party scripts and consider lazy loading non-critical scripts.
