“The role of page experience signals is to evaluate and measure the experience of users while interacting with a website page.” 

• Mobile-friendliness
• Secure browsing
• HTTPS-security
• Intrusive interstitial

Understanding All 3 Core Web Vitals 

• LCP (Largest Contentful Paint)
• FID (First Input Delay)
• CLS (Cumulative Layout Shift) 

• Good (If the site response time is less than 100 milliseconds) 
• Needs Improvement (If the site response time is more than 100 milliseconds but less than 300 milliseconds)
• Poor (If the site response time is more than 300 milliseconds) 

• Good (If the CLS score is less than 0.1)
• Needs Improvement (if the CLS score is more than 0.1 but less than 0.25)
• Poor (if the CLS score is more than 0.25) 

Tools for measuring Core Web Vitals

• PageSpeed Insights
• Chrome UX Report
• Search Console
• Chrome DevTools 
• Lighthouse 
• Web Vitals Extension

All three core web vitals can be evaluated in Javascript  by using standard web APIs. The web-vitals JavaScript library is the most simple way to calculate each metric of core web vitals. Measuring each metric with web-vitals JavaScript library is as simple as calling a single function:

import {getCLS, getFID, getLCP} from 'web-vitals';

function sendToAnalytics(metric) {
  const body = JSON.stringify(metric);
  // Use `navigator.sendBeacon()` if available, falling back to `fetch()`.
  (navigator.sendBeacon && navigator.sendBeacon('/analytics', body)) ||
      fetch('/analytics', {body, method: 'POST', keepalive: true});
}

getCLS(sendToAnalytics);
getFID(sendToAnalytics);
getLCP(sendToAnalytics);
