Amazon registers very high shopper numbers for clothing and footwear: some 45.9% of all clothing and footwear shoppers we surveyed said that they had bought apparel on the site in the past 12 months. With regard to respondents’ current expectations, our survey findings suggest that Amazon Fashion’s total shopper numbers will increase modestly in the next 12 months, and that the number shoppers who are not Prime members could increase at a faster pace than the number of shoppers who are Prime members.
“Amazon has access to data that nobody else has,” said James Thomson, a former Amazon executive who now works at Buy Box Experts, a consulting firm that advises companies on how to build their brands and sell products on Amazon. “I can’t just walk into a store and say, ‘Excuse me, did you look at this brand of cereal this morning and decide not to buy it?’ Amazon has that data. They know you looked at a brand and didn’t buy it and they’re not going to share that data with any other brands.”
The company launched amazon.com Auctions, a web auctions service, in March 1999. However, it failed to chip away at the large market share of the industry pioneer, eBay. Later, the company launched a fixed-price marketplace business, zShops, in September 1999, and the now defunct partnership with Sotheby's, called Sothebys.amazon.com, in November. Auctions and zShops evolved into Amazon Marketplace, a service launched in November 2000 that let customers sell used books, CDs, DVDs, and other products alongside new items. As of October 2014, Amazon Marketplace is the largest of its kind, followed by similar marketplaces from Sears, Rakuten and Newegg.
