E-commerce Data Analysis System Building and Operations Decision Support

E-commerce operations has entered the data-driven era. Establishing a comprehensive data analysis system is the foundation for improving operational efficiency and decision quality.

1. Core KPI System

Traffic metrics: unique visitors (UV), page views (PV), click-through rate (CTR), bounce rate, average session duration. Conversion metrics: conversion rate, average order value, payment amount, paying buyers, add-to-cart rate, favorite rate. After-sales metrics: refund rate, refund amount, dispute rate, DSR score. Operational efficiency metrics: inventory turnover, sell-through rate, ROI, advertising ratio. User metrics: repurchase rate, new customer ratio, customer lifetime value (LTV). A full-chain KPI system from traffic to after-sales must be established.

2. Data Collection and Integration

Data sources: platform backend (Shence, JD Shangzhi), advertising platforms (Zhicheche, Diamond Exhibition), customer service systems, ERP systems, third-party tools (Shence, Dianzhentan). Data integration: consolidate multi-platform, multi-system data into a unified data warehouse with standardized data definitions. Excel (small scale), Python/SQL (medium scale), BI tools (Tableau, Power BI, FineBI, large scale) can be used for data processing and analysis.

3. Analysis Framework and Methods

Common analysis frameworks: people-product-place analysis (audience profiling, product structure, scenario traffic), funnel analysis (exposure → click → add-to-cart → payment → repurchase conversion at each stage), comparative analysis (year-over-year, month-over-month, competitor comparison), attribution analysis (each channel's sales contribution), RFM analysis (customer segmentation by recency, frequency, monetary value), cohort analysis (same-cohort retention analysis). Analysis should progress from "what" to "why" to "how," forming actionable optimization recommendations.

4. Visualization Dashboard and Decision Making

Build operations data dashboard: real-time monitoring of core metrics (sales, conversion rate, traffic, inventory), anomaly alerts (automatic reminders for metric spikes), trend analysis (daily/weekly/monthly trends), channel comparison (ROI by traffic channel). Dashboards should serve different roles (operations see real-time data, management see summary data, executives see core KPIs). Data-driven decision making: adjust product selection, pricing, promotion, and inventory strategies based on data analysis, avoiding gut-feel decisions. Holding weekly data analysis meetings to review operational performance is recommended.
