Site speed is a critical factor for both user experience and SEO. Slow-loading pages can frustrate users, leading to higher bounce rates and lower engagement. For voice search, where users expect quick answers, site speed is even more crucial. Additionally, search engines like Google consider site speed as a ranking factor.
