1. Next-Gen Image Formats
Convert legacy JPG and PNG formats to modern AVIF or WebP standards. Utilize responsive srcset attributes and lazy loading to minimize unnecessary asset transfers.
2. Asynchronous Script Strategy

3. Global Content Delivery Networks (CDN)
Serve static assets from regional edge servers closest to user locations to achieve sub-second TTFB globally.
