Primary Product – Understanding Its Role in Product Relationships

A primary product refers to the main product to which other related products are connected. For instance, if you're searching for a substitute for a discontinued item you currently own, the item you own is considered the primary product.

Types of Related Products

We associate various types of related products with many of our primary products. These include:

• Upgrades: Enhanced alternatives that offer superior performance compared to the primary product.
• Accessories: Add-ons that improve or complement the functionality of the primary product.
• Substitutes: Similar products that can replace the primary product when needed.
• Supersedes: Updated versions that have replaced the primary product.
• Related Products: Items from different categories that pair well with the primary product.

You can find these product relationships displayed on the following pages:

• Product Detail Page
• Shopping Cart
