Category Mapping

Updated March 2026

Category mapping is the process of linking your store’s product categories with Mastersel’s standardized category system. This is a critical step because marketplaces rely on correct categorization to display products in the right sections and to apply the appropriate marketplace rules.

Why Mapping Is Required

  • Correct product classification — products appear in the right marketplace category, improving visibility
  • Activation prerequisite — products cannot be activated without a mapped category
  • Listing quality — proper categorization improves search results and customer discovery
  • Compliance — some categories have specific marketplace requirements (e.g., safety certifications)

How to Map Categories

  1. Open the Category List in your dashboard — you’ll see all categories imported from your store
  2. Select the store category you want to map
  3. Browse or search the Mastersel category tree to find the best match
  4. Save the mapping — all products in that category are now properly classified

Mapping Parameters

In addition to categories, you should also map product parameters (attributes) such as color, size, material, weight, and other product-specific properties. Parameter mapping ensures your products display the correct attributes on marketplace listings, improving discoverability and customer trust.

You can also set default product weight per category in the mapping system. This is useful if individual product weights are not available in your store data — the category-level weight will be applied to all products in that category.

Tip: Choose the most specific category available. For example, instead of mapping to “Electronics,” map to “Electronics > Personal Care > Electric Toothbrushes.” More specific categorization leads to better marketplace placement.
