According to a study by eMarketer, the top three online shopping sites in the world in 2023 will be Amazon, Alibaba, and eBay. These three sites will account for 54.8% of all online retail sales. This is a huge increase from the 34.2% share they had in 2016.

The growth of online shopping is due in part to the growing demand for convenience, as well as the increasing number of people who are using smartphones and other mobile devices to purchase products. Additionally, the growth of online shopping is also due to the increasing number of international shoppers.

The eMarketer study also found that the growth of online shopping will be particularly strong in the Asia-Pacific region, where it will account for 73.8% of all online retail sales. This is followed by North America (20.2%) and Europe (12.5%).
