Best Sellers Rank

The Best Sellers Rank operation (BEST_SELLERS_RANK) returns a product's current Best Sellers Rank on Amazon, together with basic product details. You identify the product by its asin and the marketplace by its domain.

When to use

• Track a product's rank over time by polling it on a schedule and storing each snapshot.
• Compare your products with competitors in the same category or subcategory.
• Check demand for a product type before you list or source it.
• Spot products whose subcategory rank improves quickly.
• Audit the ranks of a whole catalog with the Bulk API.

What the response includes

The response structure depends on the operation version. Version 2 is the Live version since November 1, 2026, so requests without operation_version receive it. It responds faster and includes subcategory ranks. Version 1 is the legacy structure (see Operation Versioning).

Version 2:

• Product identification: asin, short title, brand_name, manufacturer and the product link.
• Main category and subcategory rank summary, each with its category title and Best Sellers list link (bestseller).
• Every Best Sellers list the product is ranked in, with rank, title, link and level (bestsellers).
• The full-resolution main image (image).

Version 1 (legacy):

• Product identification and commercial data: asin, full title, brand_name, price, currency and link.
• Main category rank, category name and subcategory browse node ID (bestseller).
• Primary image and thumbnail links (media).
• Rating summary (reviews).

See the Best Sellers Rank response for all fields and the migration table.

Note

Version 2 does not return price, currency or review data. If you need them, use the Detail operation (DETAIL). See the Detail response.
