Common Amazon Acronyms!




Amazon loves to use acronyms so thought it would be useful to put together an acronym guide of some of the most commonly used terms. This is a mix of seller, vendor and advertising terms.

· ASIN – Amazon Standard Identification Number – An Amazon Standard Identification Number (ASIN) is a 10-character alphanumeric unique identifier assigned by Amazon.com and its partners for product identification within the Amazon organization.


· ACoS – Advertising Cost of Sales - Advertising Cost of Sales, is how much you spend on advertising per pound [SS1] of advertising revenue you make. You can also think of ACoS as the ratio of ad spend in contrast with the total ad revenue. ACoS = Total Ad Spend / Total Ad Revenue.


· TACOS – Total Average Cost of Advertising – Total Advertising Cost of Sales, is how much you spend on advertising per pound of total revenue you make. TACOS = Total Ad Spend / Total Account Revenue.


· LBB – Lost Buy Box – The Buy Box is the display on a product detail page with the Add to Cart button that customers can use to add items to their shopping carts. When one of your listed items appears as the default on the product page, you “win” the Buy Box, increasing your chances of selling that item.


· PO (vendor) – A purchase order (PO) is an official document that's issued by Amazon to a vendor for the purchase of a vendor products. Typically, a PO includes the types, quantities and prices of the products or services being purchased by the vendor. Note, PO’s are only issues to vendors on Amazon, not sellers.


· Impressions/Sessions – These basically refer to the visits to your detail pages by a user. All activity within a 24-hour period is considered a session.


· CVR – Conversion Rate – The conversion rate refers to the percentage conversion metric indicating how many units were purchased relative to the number of people who viewed the product. In other words, CVR = Orders/Clicks.
