AliExpress optimizes titles to improve relevance and commercial value. First, a good title should contain keywords related to the product, which helps to increase the product's exposure in search results.

Second, the title should contain information such as the product's core selling points, brand, model, etc., which helps to attract clicks from potential customers.

At the same time, commercial terms are also indispensable, such as promotions, discounts, gifts, etc. These terms can attract more potential customers and promote sales. In short, AliExpress optimizes titles to comprehensively consider relevance and commercial value in order to increase product exposure and click-through rates, and ultimately achieve sales growth.
