As the world's largest e-commerce platform, Amazon has many sites to choose from, such as the United States, the United Kingdom, Germany, Japan, etc. Which site to choose depends on factors such as the products you want to sell, the target customer group, and logistics conditions.

If you want to target the US market, you can choose the US site; if you want to expand the European market, you can choose the German or British site. In addition, you also need to consider factors such as the competition situation and policy regulations of each site. In short, you must carefully analyze and choose according to your own situation and needs.
