Everything you need

Revenue Intelligence

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.

Revenue Intelligence

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.

Revenue Intelligence

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.

Performance Optimization

AI-Driven Prerendering

Superspeed uses a multi-tiered predictive algorithm that analyzes checkout data to figure out exactly what your customers want to buy before they even click. We pre-render the highest converting pages in the background, resulting in a zero-latency buyer journey.

Performance Optimization

Automated CLS Prevention

Our layout stabilizing engine seamlessly locks unstable images in place before your page even loads, preventing frustrating misclicks and creating a smooth, unshakeable browsing experience.

Performance Optimization

Inline Script Sandboxing

Our Smart Blocker automatically sandboxes third-party scripts, stopping them from running until your main product page is completely interactive. Keep your marketing attribution intact while boosting performance.
