500K SKU Catalogue Quality Programme for Marketplace
Catalogue remediation and ongoing governance for a large online marketplace with significant product data quality issues.
The Challenge
A large B2C marketplace with 500K+ active SKUs was experiencing a 12% listing error rate — incorrect attributes, duplicate listings, policy violations, and missing imagery — resulting in poor search rankings, high return rates, and seller disputes.
Our Approach
Deployed a 45-person catalogue operations team structured into enrichment, moderation, image QA, and attribute validation squads.
Conducted full catalogue audit across 500K SKUs — categorised by error type, severity, and category.
Built a taxonomy-based attribute checklist for 240 product categories, enabling consistent, scalable enrichment.
Established a 48-hour SLA for new SKU onboarding: intake → enrichment → QA → publish.
Implemented weekly data quality dashboards tracking error rate by category, seller, and product type.
