The Amazon sales rank (ASR) provides an indication of the popularity of a product sold on any Amazon locale. It is a relative indicator of popularity that is updated hourly. Effectively, it is a "best sellers list" for the millions of products stocked by Amazon. While the ASR has no direct effect on the sales of a product, it is used by Amazon to determine which products to include in its bestsellers lists. Products that appear in these lists enjoy additional exposure on the Amazon website and this may lead to an increase in sales.

Anyone looking for the same level of success with their own product can pitch their idea to both Telebrands and As Seen On TV, Inc. although they only accept a few submissions each year.
