How does website performance affect mobile users?

Website performance significantly affects mobile users, who often have slower connections and less powerful devices. Mobile users are more impatient—53% abandon sites taking over 3 seconds to load. Poor mobile performance leads to high bounce rates and lost conversions. Mobile performance is especially important as mobile traffic represents 60-70% of web traffic. Google uses mobile performance for rankings (mobile-first indexing). Performance optimizations often have bigger impact on mobile than desktop. Good consultants prioritize mobile performance, testing on actual devices and slow connections. Mobile optimization includes image optimization, code minimization, and efficient loading strategies.
