SKU (Stock Keeping Unit)
A SKU is a unique alphanumeric identifier assigned to a specific product variant — including its size, color, and other attributes — used to track inventory and sales.
Every distinct product variant has its own SKU. A single sneaker model in 5 colors and 10 sizes would have 50 SKUs. SKUs are the atomic unit of inventory management, pricing, and competitive analysis.
In competitive intelligence, tracking SKUs means knowing exactly which specific variants a competitor carries. When a competitor adds a new SKU (e.g., a new color of their bestselling product), it signals a product expansion. When a SKU disappears, it may indicate stock-out, discontinuation, or a quiet product recall.
GetStoreIntel performs SKU-level diffing on every crawl cycle, alerting you to new, removed, or changed variants across all tracked competitor stores.
