Ecommerce analytics for a beauty brand means using unified data from Shopify, Amazon, paid social, and email to answer the specific questions beauty founders actually face: when to reorder a hero SKU before a stockout, which TikTok video is driving real Shopify conversions versus just views, and whether a new product launch is cannibalizing margin from an existing bestseller. These aren't generic ecommerce questions. They're beauty-specific decisions that require beauty-specific data views.
