The Core Web Vitals strongly impact the way that users interact with your website. Google is becoming increasingly focused on user experience, which means websites need to do the same. Core Web Vitals identify user experience issues by generating a metric for three key areas of user experience, including:
Page loading performance
Ease of interaction
Visual stability of a page from a user’s perspective
Additional metrics Google analyses are whether your website is mobile-friendly and provides safe browsing and non-intrusive content such as pop-ups and ads.
