Elevating User Experience with Core Web Vitals


In 2020, the introduction of Core Web Vitals marked a significant milestone in web development. These vital metrics were introduced to improve user experiences on webpages. Since their inception, Core Web Vitals have played a pivotal role in enhancing web performance, with more than 40% of websites now successfully meeting all metrics.

Collaborative Efforts for a Faster Web

The journey to these achievements was made possible through the collaborative efforts of Google Search and Chrome teams. The aim was to set a universal standard for a faster, more user-friendly web. To achieve this, algorithms were updated to prioritize speed and usability, thereby establishing a new benchmark for web performance.

The Impact of Minor Changes

While the improvements resulting from these changes may seem modest, their impact has been significant. The average page load time in Chrome has been reduced by 166 milliseconds, collectively saving users over 10,000 years of waiting time. Furthermore, the percentage of sites meeting Core Web Vitals metrics has witnessed remarkable growth.


Optimizations for Enhanced User Experiences

Chrome's unwavering commitment to enhancing user experiences has led to several key optimizations:

  • Back/Forward Cache (BFCache)
  • PreconnectOnAnchorInteraction
  • Prerendering for instant page loading
  • Tab throttling and task role adjustments
  • Multiple active tab optimizations
  • Improvements in page loading code
  • Enhanced renderer prioritization


The Continuous Pursuit of Speed

Chrome's mission is to provide a fast, efficient, and high-quality web experience. This commitment to continuous improvement ensures users continue to enjoy a responsive and seamless web journey.
