How does website performance affect conversions?

Website performance directly affects conversions—slow sites lose users. Research shows that each second of delay can reduce conversions by 7%, and 53% of mobile users abandon sites that take over 3 seconds to load. Fast sites improve user experience, reduce bounce rates, increase time on site, and improve search rankings. Performance also affects user trust—slow sites feel unprofessional. Mobile performance is especially critical since mobile users are more impatient. Example: An e-commerce site improved load time from 5 seconds to 2 seconds and saw 25% increase in conversions, with mobile conversions increasing even more (35%).
