Buy Box
What Is the Buy Box?
The Buy Box is the primary purchase area on a marketplace product page where customers click the main Add to Cart or Buy Now button.
When multiple sellers offer the same product, the marketplace selects one seller to win the Buy Box at any given time.
In essence, the Buy Box determines which seller gets most sales for a shared product listing.
Why the Buy Box Matters for Brands
For brands and sellers on marketplaces, winning the Buy Box has a direct impact on visibility, conversions, and revenue.
Most customers purchase from the seller featured in the Buy Box rather than reviewing alternative offers.
Key benefits:
Higher conversion rates and sales volume
Greater visibility without additional ad spends
Increased trust through marketplace endorsement
Examples of the Buy Box in Action

Buy Box eligibility may be influenced by:
Competitive pricing and total landed cost
In-stock availability and fast shipping
Seller performance metrics such as ratings and cancellations
Accurate content and compliant product data
Sellers that consistently meet these criteria are more likely to win and retain the Buy Box.

Feed Readiness Use Cases: To ensure pricing, inventory, and identifiers are accurate
