Web Vitals helps make up the page experience ranking factors, including:
• Mobile-friendliness—whether or not your site is optimized for mobile.
• HTTPS—is your site using a secure connection?
• Interstitial use–does your site stay away from nasty pop-ups?
These new user-centered metrics take into account everything a user experiences on a website to try to come up with a more holistic view of your site’s performance.
