How Core Web Vitals saved users 10,000 years of waiting for web pages to load

The Fast and the Curious post highlights how Core Web Vitals (CWV) have significantly improved web performance, saving Chrome users over 10,000 years of waiting for web pages to load in 2023. Introduced in 2020, CWV metrics have led to over 40% of sites passing all metrics, resulting in faster loading and more responsive pages. Chrome's collaboration with Google Search teams addressed slow web pages by defining public standards for fast, user-friendly pages and updating search ranking algorithms. The average page load in Chrome is now 166 ms faster, with projections indicating continued improvement in CWV pass rates. Chrome has implemented various optimizations, including back/forward cache improvements, preconnect features, and prerendering, which have led to substantial performance gains. The broader developer ecosystem, particularly WordPress and JavaScript frameworks, has also achieved remarkable results by focusing on CWV. These performance improvements have translated into real-world benefits for businesses, with companies reporting increased conversion rates, page views, and reduced bounce rates. The developer community's efforts in monitoring and optimizing for CWV have been crucial in sustaining these improvements, with high developer satisfaction rates and notable improvements in CWV scores.
