THE HISTORY OF CORE WEB VITALS

Summary from the TLDR Dev newsletter

Core Web Vitals was launched by Google in May 2020 as a set of standardized metrics that measure user experience by assessing website loading speed, interactivity, and visual stability. The initiative was meant to be a more open approach to improve web performance, and has reportedly saved Chrome users over 30,000 years of waiting time through 2024 by encouraging website optimization. These metrics were developed based on research showing that pages meeting the Core Web Vitals thresholds see 24% fewer user abandonments.
