ASIN (Amazon Standard Identification Number)
An ASIN is a unique 10-character ID that Amazon gives to every product in its catalog. It is how you point an ad at a specific product, yours or a competitor’s.
Example
Every Amazon product page has one, and it is listed in the product details and in the page address, such as B0XXXXXXXX. You can use an ASIN to target a specific product with your ads.
Where it matters most: Book 5, The Advanced PPC Clarity Guide, in the chapter “Reading a Competitor's Move, and ASIN Targeting.”
