The Web Vitals initiative has been launched by Google to provide a standard approach to measuring websites' performance and user experience.

The initiative is based on a series of metrics that will assess the quality of a website and understand how it affects the user experience.

The core idea behind Web Vitals is to simplify the landscape and help web developers focus on the metrics that matter most.

The objective is to use a series of metrics to make a judgement on whether or not your website has a good user experience.

A website that is slow or not responsive is bad for users. That's why it should be considered a leading indicator.
