Structural Site Assessment to Drive EC Revenue

Break out of partial optimization in e-commerce (EC) and break through the revenue ceiling. A diagnostic guide that pinpoints root causes — from page-load speed to organizational design — through a causal model

We present the data showing that page-load speed directly drives CVR: a 1-second LCP improvement raises CVR by 2%, and Walmart realized a USD 1.2 billion (120 billion yen) revenue uplift from a 2-second improvement

53% of mobile users arriving from advertising abandon a site beyond 3 seconds. We make visible the reality that up to 50% of ad spend is wasted solely due to page-load issues

Our proprietary 98-item framework — several times the scope of a standard EC diagnostic — structurally assesses the interlocking causes across performance, semantic IA, advertising, CRM, and measurement

A cross-functional team of PdMs, engineers, and marketers integrates measured WPT data, GA4/BigQuery analysis, and technical review to pinpoint root causes

Prescriptions are grounded in a causal model with explicit KPI structure and revenue contribution, delivering sustained growth through root-cause treatment rather than symptomatic fixes

Overview

A must-read for EC leads whose revenue plateaus despite continued advertising and UI improvements. This document explains a diagnostic process using a causal model that makes visible how each EC element — page-load speed, information architecture, measurement foundations — drives downstream impact. It covers the 50% ad-spend loss risk caused by 3-second delays, 98 assessment items grounded in world-class theory, and concrete improvement outcomes. It is a comprehensive view of the frontier for sustained growth, delivered through root-cause treatment rather than symptomatic fixes.
