1. AliExpress follows the Taobao strategy of "price is king". The platform has a low entry threshold and the platform commission is lower than that of eBay and Amazon. This has led to the influx of many entrepreneurs, and the homogeneous competition is relatively fierce. Many sellers can only gain advantages through low prices (among them, there are many sellers who use tricks to obtain high profits). In addition, AliExpress will have surprises: small wholesale orders from Alibaba. If the supply chain of a single category of products is very complete and very competitive, you can quickly succeed in AliExpress. If you fight a price war, other small sellers will definitely die. Keep uploading products and lowering prices. Powerful sellers will directly find factories to offer factory prices or use the method of clearing inventory. This is a fatal blow to other middlemen, leaving them with no way out. It doesn't matter if there is a brand or not, as long as there is a price advantage. AliExpress has attracted many sellers of this kind of products and is suitable for beginners; 2. eBay. Compared with AliExpress, eBay has stricter requirements on sellers and higher requirements on product quality, but it also competes on price. Even if the product quality is acceptable, the price must be advantageous to win favor. It is recommended that production factories can try to do eBay. The threshold is relatively high because the market and customer groups are different. AliExpress is mainly in developing and underdeveloped countries (Russia, Brazil, etc.), while eBay is a mature market with high quality requirements and rules that are more biased towards buyers. If the products, services, and logistics are not done well, you will lose a lot of money. Sometimes it is not enough to have a strong product, and other capabilities are required, such as localized services (overseas warehouses, local brand packaging);

3. Among these three platforms, Amazon has the highest requirements for sellers. It is product-driven, that is, the product quality must have advantages, and it must also have a brand. If you don’t have a brand, it’s best not to do Amazon, otherwise there will be endless troubles (see "Things about Amazon Brand Protection" reprinted by Xiaoma Kan Cross-border E-commerce). At present, Amazon has the highest entry threshold and more detailed conditions. Once it is done, the profit is also very considerable. Generally speaking, hard work pays off.
