Revenue Leak Detection
Superspeed's Predictive Conversion Engine correlates session performance with cart telemetry. We calculate the exact conversion rate difference between visitors experiencing "fast" loads and "slow" loads to output the precise amount of revenue lost—all without giving away the secret sauce.
Ghost Checkouts & Rage Clicks
Our Abandoned Cart Killer algorithm captures rapid, repeated clicks on unresponsive elements and links them to cart abandonment. We calculate the value of these ghost checkouts to evaluate recovery opportunities and pinpoint exactly where shoppers are dropping off.
Real User Monitoring (RUM)
Our silent cart telemetry gathers stats directly from visitor browsers in the background. It seamlessly tracks Web Vitals and network latency, causing zero interference with the actual buyer journey.
