## AI overview

This article explains how Core Web Vitals helped improve web performance for Chrome users on desktop and Android, reportedly saving more than 10,000 years of page-loading time in 2023. It describes how shared metrics, developer guidance, and collaboration across Chrome, Search, and the web ecosystem contributed to faster, more responsive pages.

Today's The Fast and the Curious post explores how Core Web Vitals saved Chrome users more than 10,000 Years of waiting for web pages to load in 2023 (across Chrome desktop and Android) by quantifying the experience of sites and identifying opportunities to make improvements. In 2020, we introduced Web Vitals - essential quality signals for webpages to ensure a better user experience. Since then, there has been a massive leap in web performance made possible by our work on Core Web Vitals (CWV) and its broader impact on the web. Today, over 40% of sites pass all of the CWV metrics, leading to pages that load and respond to interactions more quickly. Here's a closer look at the journey to help improve the performance for sites and some specific work done in the browser and the ecosystem to enable this achievement. Chrome's Quest for Speed The very essence of the web lies in its ability to provide information and services efficiently and rapidly. This principle is at the heart of Google's business and drives our work on Chrome. However, we noticed an issue with sites over a long time horizon. Even if slow sites improved their performance for a while, it would often decline over time. No matter how fast Google Search might be, the user experience would be subpar if the pages found were slow to load. We could not help these sites improve their performance directly, but we wanted users to have a great experience when they moved from Google Search to the individual sites. To tackle the challenge of improving the user experience while simultaneously providing unified guidance to developers, teams from Search and Chrome collaborated to address the issue of slow web pages. Defining the Fast Web We examined millions of pages to define a public standard for a fast, user-friendly web page (initially published in The Science Behind Web Vitals). We published our specifications and data to the open ecosystem and took note of the feedback we received. The introduction of CWV metric
