Porter Road Revenue Leak Analysis
Despite having a highly responsive architecture (INP: 132ms), Porter Road is bleeding revenue before shoppers even see their products. An agonizingly slow LCP of 3.9s forces paid traffic to stare at a blank screen, directly causing massive ghost checkouts. Their First Contentful Paint (FCP) of 3.5s is also a major friction point, leaving shoppers staring at a blank white screen for far too long. Until they plug these revenue leaks, Porter Road will continue to burn money on paid ads that bounce instantly.

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.
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.
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.
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.
