The advantages of Amazon's Spanish site are mainly as follows:

1. Market size: Although the Spanish market is relatively small, it is still one of the most dynamic e-commerce markets in Europe, so it has certain business opportunities.

2. Consumption level: Spanish people are very fond of Chinese products, which means that Chinese sellers can achieve good sales performance on this site.

3. Amazon's brand effect: As one of the world's largest online retailers, Amazon enjoys a high brand awareness and reputation worldwide, which helps sellers improve the credibility and attractiveness of their products.

4. Logistics advantages: Amazon has warehouses and logistics networks in Spain, which can provide sellers with fast and reliable logistics services to help sellers better meet customer needs.

It should be noted that the disadvantages of the Spanish site also exist, such as the overall consumption level is not high enough, the profit is relatively low, and there are many Chinese sellers. Sellers need to analyze and make decisions based on the actual situation.
