The Challenge

Scaling beauty commerce with a 300+ brand catalog

Sephora needed deeper product, brand, and category-level visibility to bring Meta and Google performance in India closer to other geographies.

About the Brand

Sephora is a global leader in prestige beauty retail — operating across skincare, makeup, haircare, fragrances, and 300+ curated brands in India through a robust e-commerce platform and physical stores.

With both online and offline presence, the brand needed a more connected approach to performance marketing — moving from manual, siloed reporting to a product-led system built for scale across Meta and Google.

Limited Product, Brand & Category Insights

Performance data was spread across Meta Commerce Manager, Google Merchant Center, and e-commerce systems — making it difficult to track product-level KPIs efficiently.

Limited Control Over Spend by Category

As a beauty marketplace with multiple brands and categories, Sephora needed better control over which brands, categories, and products received ad visibility.

Ad Spend Leakage on Poor Performers

Around 25% of ad spend across Meta and Google was being wasted on poor-performing products, reducing efficiency and limiting scale.

The Approach

Product Performance Management

BigAtom segmented Sephora’s 300+ brand catalog into four performance-based groups — enabling sharper ad spend decisions at the product, brand, and category level.

Low Spend · High ROAS

High Potential Products

Profitable brands and SKUs receiving insufficient visibility — emerging categories and trending beauty products with strong conversion signals but underleveraged budgets.

High Spend · High ROAS

Hero Products

Top-performing SKUs across skincare, makeup, and fragrance — proven bestsellers prioritised for dedicated Product Sets generating 13× ROAS.

Low Spend · Low ROAS

Low Discoverability

Brands and products with limited exposure needing controlled testing before confident budget allocation across Meta and Google campaigns.

High Spend · Low ROAS

Non-Performers

SKUs consuming 25% of budget without returns — automatically excluded via Stop-Loss Automation, freeing spend for profitable brands and products.

Execution

Three targeted strategies

Product-level analytics, targeted Product Sets, and automated stop-loss rules combined to build a scalable performance engine for Sephora’s beauty catalog.
