Akamai mPulse vs Google Core Web Vitals
Head-to-head usage across the sites we track.
Detections for Google Core Web Vitals end in Jan 2022. The fingerprint catalog behind our crawls no longer carries that technology as its own entry, usually because it was retired or split into more specific ones, so its figure is the last recorded and is not directly comparable with a currently tracked technology.
