Optimizing for Bangladesh means designing for 3G/4G with high latency. Slow speed kills conversions instantly.
Local stores love spin-wheels, WhatsApp bubbles, countdown timers. Each injects JS. I audited a store with 14 apps — removing 6 saved 1.8 seconds.
Use font-display: swap; to prevent Flash of Invisible Text. Show system font first, load custom in background.
<script src="pixel.js" defer></script>
Render visuals first, analytics later.
Conclusion: Clean code, limit third-party scripts, compress images. Faster store = more checkouts.
