Website performance is no longer optional. In today’s competitive digital landscape, performance optimization lazy loading plays a critical role in delivering fast-loading, SEO-friendly, and user-focused websites.
At PT Code Hero Indonesia, we help businesses build high-performance websites that meet global SEO standards while maintaining excellent user experience.
What Is Lazy Loading?
Lazy loading is a performance optimization technique that delays loading non-critical resources until they are actually needed by the user.
Instead of loading all images, videos, and embedded content at once, the browser loads only what is visible in the viewport.
- Faster initial page load
- Reduced server and bandwidth usage
- Better mobile performance
- Improved Core Web Vitals

Proper lazy loading improves:
- Largest Contentful Paint (LCP)
- Interaction to Next Paint (INP)
