AliExpress semi-hosting and full-hosting each have their own advantages and disadvantages. Which one is better needs to be judged based on the specific needs and business strategies of the merchants.

Advantages of the full-hosting model:

1. Traffic concentration: The full-hosting model helps the platform to concentrate traffic, bringing more exposure and sales opportunities to merchants.

2. Reduce costs: The full-hosting model can achieve large-scale operations, reduce commodity costs, and increase merchant profits.

3. Simplify operations: Merchants only need to be responsible for listing products and preparing stocks, and other links such as logistics and marketing are the responsibility of the platform, reducing the operating pressure of merchants.

Disadvantages of the full-hosting model:

1. Limited pricing power: Under the full-hosting model, merchants need to give up some pricing power, which may lead to limited profit margins.

2. High dependence on the platform: The full-hosting model makes merchants highly dependent on the platform, which may affect the merchants' own brand building and operation capabilities.

Advantages of the semi-hosting model:

1. Retain pricing power: In the semi-hosting model, merchants can retain pricing power and better control profit margins.

2. Flexible operation: The semi-hosting model is more flexible than the full-hosting model, and merchants can choose appropriate logistics, marketing and other services according to their own needs.

3. Brand building: The semi-hosting model helps merchants to build their brands and improve their own operational capabilities.

Disadvantages of the semi-hosting model:

1. Operational pressure: In the semi-hosting model, merchants need to be responsible for some operational work, such as logistics, returns, etc., and the operational pressure is relatively large.

2. Service cost: In the semi-hosting model, merchants need to pay a certain service fee to the platform.

In summary, if you focus on brand building and profit margins, and have certain operational capabilities, you can choose the semi-hosting model. If you want to simplify the operating process, reduce costs, and increase sales, you can choose the full-hosting model. Which model you ultimately choose depends on your specific needs and business strategies.
