What is ASIN?

ASIN (Amazon Standard Identification Number) is the unique 10-character code Amazon assigns to every product. Listing, advertising, reporting and competitive analysis all run through this code.

Detail

Duplicating the same product across separate ASINs ("duplicate listing") violates Amazon policy and hurts you by splitting reviews. The right approach is to gather variants under a single parent ASIN, so reviews accumulate and ranking strengthens.

Example

Putting five colours under one parent ASIN as variants pools the review count instead of splitting it five ways.
