Everything you need to know about tracking your page experience metrics.
Core Web Vitals are three key metrics that measure user experience: LCP (loading), FID (interactivity), and CLS (visual stability). Google uses these metrics as ranking factors.
PageSpeed Insights only provides manual, one-time testing. PageRadar continuously monitors your Core Web Vitals 24/7 with real user data, sends alerts when performance degrades, and tracks trends over time so you can spot issues FAST.
We use Google's official PageSpeed Insights API and Chrome User Experience Report (CrUX) API to gather data. For high-traffic websites, you'll get real user field data from Chrome users. For smaller sites, you'll receive reliable synthetic testing data plus TTFB.
For good user experience : LCP under 2.5 seconds, INP under 200 milliseconds (replaced FID in 2024), CLS under 0.1, and TTFB under 600ms for server performance.
We fetch fresh data from Google's APIs daily.
