Why Performance Matters
Website performance directly impacts user experience, search engine rankings, and conversion rates. Studies show that:
of mobile users abandon sites that take longer than 3 seconds to load
reduction in conversions per 1-second delay in page load time
Google uses Core Web Vitals as ranking factors for search results
Faster websites provide better accessibility for users on slower connections
