Protecting Organic Demand During a 10K+ SKU eCommerce Migration

Overview

An eCommerce brand with a custom ERP system needed a reliable 1:1 redirect mapping process for more than 10,000 product variants and SKUs.

Because the catalog was driven by complex ERP data, a generic redirect export would not be enough. Product variants, SKU-level URLs, and similar naming conventions created a high risk of missed or mismatched redirects.

Result: Zero missed redirects for product variants, helping retain captured organic demand and minimize migration-related visibility loss.

The Challenge

The migration required accuracy at scale.

The site included:

• 10,000+ product variants and SKUs
• ERP-driven product data
• Variant-level URL structures
• Similar product naming conventions
• High risk of redirect gaps or incorrect mappings

A missed redirect could mean lost rankings, broken product journeys, and revenue leakage.

My Role

I designed and supported the redirect mapping process, including:

• Reviewing legacy product URL structures
• Understanding how the ERP generated product and variant URLs
• Building scalable mapping logic
• Validating old-to-new URL pairings
• Preparing the redirect handoff for development

The Strategy

The goal was simple: every valuable product URL needed the most relevant destination possible.

Instead of relying on broad category redirects, the process prioritized:

• Product-to-product matches
• Variant-to-variant matches
• SKU-level accuracy
• Clean destination URLs
• Reduced redirect chains
• QA before implementation

This protected both search equity and user experience during the migration.

The Outcome

The process achieved zero missed redirects for product variants.

The migration retained existing product-level demand, protected SKU relevance, and reduced the visibility loss that often follows complex eCommerce migrations.
