\n\n\n\nFrequently Asked Questions About Amazon Terms & Acronyms<\/h2>\n\n\n\n
An Amazon glossary is a reference guide that defines the acronyms, metrics, and platform terms sellers encounter in Seller Central, Vendor Central, and Amazon Advertising \u2014 such as FBA, ACoS, ASIN, and Buy Box.<\/p>\n\n\n\n
ACoS means Advertising Cost of Sale. It is calculated as ad spend divided by ad-attributed sales and measures how efficiently your Amazon ads generate revenue.<\/p>\n\n\n\n
ACoS looks only at ad-attributed sales. TACoS divides ad spend by total sales (organic + paid), giving a clearer view of whether advertising is building overall profitable growth.<\/p>\n\n\n\n
FBA stands for Fulfillment by Amazon. Amazon stores your products and handles picking, packing, shipping, customer service, and returns for FBA orders.<\/p>\n\n\n\n
With FBA, Amazon fulfills orders. With FBM (Fulfillment by Merchant), you fulfill orders yourself. FBA is often easier for Prime eligibility; FBM offers more operational control.<\/p>\n\n\n\n
ASIN stands for Amazon Standard Identification Number. It is a unique 10-character code that identifies a product in Amazon\u2019s catalog.<\/p>\n\n\n\n
The Buy Box is the main purchase box on a product page. The seller who \u201cwins\u201d the Buy Box receives the majority of sales on that listing.<\/p>\n\n\n\n
Brand Registry is Amazon\u2019s program for eligible brand owners that unlocks brand protection tools, A+ Content, and additional brand controls.<\/p>\n\n\n\n
Amazon PPC refers to pay-per-click advertising on Amazon, primarily Sponsored Products, Sponsored Brands, and Sponsored Display campaigns.<\/p>\n\n\n\n
We update this glossary as Amazon introduces new terms, sunsets old ones, and changes program names. Check the \u201cLast Updated\u201d date at the top of the page.<\/p>\n\n\n\n
