The North American site represented by the US site is Amazon’s largest site. According to data from Statista, in March 2019, the Amazon app became the main shopping app in the United States, with 145.2 million active mobile users and nearly 190 million total active users. As the largest e-commerce platform in the United States, Amazon has a large market capacity and huge consumption potential, and many sellers will choose to enter. Many things have advantages and disadvantages. The biggest disadvantage of Amazon is that there are too many sellers in the US site, resulting in very fierce competition and low profits on average. The survey found that the most popular category in the US site is electronic products. Among the top sellers, electronic product sellers account for 20%, clothing/shoes/jewelry accounts for 17%, home accounts for 13%, and health/family accounts for 12%.
The number of sellers in Mexico and Canada is very small, mainly because of the limited market, high logistics costs, and uncertainty in tariffs, which lead to strict conditions for sellers to enter. In contrast to the US site, Mexico and Canada can bring higher profits to sellers, and the future market growth space and room for improvement are more obvious.
