Amazon's sales ranking 

The Amazon sales rank provides information about a product's popularity across all Amazon locations (ASR). It is a relative popularity measure that is updated every hour. In essence, it acts as a "bestsellers list" for Amazon's millions of products. Amazon utilizes the ASR to choose which products to include on its bestsellers lists, even though it has no direct impact on a product's sales. These lists provide products with additional exposure on the Amazon website, which may increase sales. Products that see notable jumps (up or down) in their sales rankings may be featured in Amazon's "movers and shakers" listings; such a listing attracts greater attention and may increase sales. Due to worries about competition, Amazon does not publicly provide its actual sales figures. However, Amazon has just recently begun giving verified authors Nielsen Book Scan point-of-sale data. Publishers, creators, and marketers have made many assumptions about the ASR, but Amazon itself remains secretive about the method it employs to calculate sales rank.
