Whether AliExpress titles use multilingual or English depends on a variety of factors, including target audience, product type, and degree of competition. -Target audience: It is important to clearly understand the language preferences and usage habits of your target audience. If you hope to attract buyers from different countries or regions, using multilingual titles will help increase the chances of your products being browsed and purchased. -Product type: Some products may be more suitable for multilingual titles, such as electronics or fashion products, which tend to have an international audience. For localized products such as food or household items, using English titles may be more appropriate. -Degree of competition: In highly competitive product categories, using multilingual titles can help your products stand out. -Cost: Using multilingual titles also needs to consider cost factors, including translation costs and the cost of managing multilingual product listings.
