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.

Performance Optimization

Predictive Prerendering & Speculative Engine

Superspeed Neural Navigation Engine™ analyzes real-time user hover, touchstart, and purchase probability telemetry. Milliseconds before a shopper clicks a link, our active engine dynamically injects full Chrome speculation rules to pre-render the target page off-screen.

Performance Optimization

Automated Speed Engine

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

Social Media Browser Bypass

When social traffic arrives, we detect the slow in-app browser and automatically bust the user out into their native browser (like Safari or Chrome), restoring Apple Pay and unlocking maximum conversion potential.

Revenue Intelligence

Automated Health Audits

Our structured insights engine evaluates your store telemetry daily to automatically uncover hidden health warnings. We prioritize the exact fixes that will increase your store's speed without requiring an engineering degree.
