Every 100KB of JavaScript costs 1-2% of mobile conversions. Here's the full picture.
Google: every 100ms of load time = 1% conversion drop. Amazon: every 100ms = 1% revenue loss. At $10M revenue, a 500ms improvement = $500K/year in additional revenue.
Frontend optimization ROI: code splitting (2-4 weeks, $10-20K), image optimization (1-2 days, $1-2K), lazy loading (1 week, $5K), CDN implementation (1-2 days, $2-5K/year). All pay for themselves within the first quarter for any revenue-generating web application.
