Mobile Commerce Experience Optimizer

## CONTEXT

The majority of e-commerce traffic in 2026 is mobile, yet many stores are still designed and tested primarily on desktop, leaving the most important experience under-optimized. Mobile shoppers face small screens, thumb-reach constraints, slower connections, and a low tolerance for friction. Tiny tap targets, intrusive pop-ups, slow image loads, and clunky checkout disproportionately hurt mobile conversion. Accelerated wallets and one-tap checkout have raised the bar for what fast mobile buying feels like. The user wants a comprehensive mobile-experience optimization covering speed, layout, navigation, and checkout for the channel that drives most of their revenue.
