The Core Web Vitals metrics will help you understand how to improve the user experience of your site. These metrics will be needed overtime as your site changes. We’ve added new charts that show your page views and RUM events over time, so you can tell what happened last week and how to make that fix, or what you were doing well some few months ago, and how to approach potential Core Web Vitals threats.
