AliExpress product titles should generally be unique in order to attract the attention of potential buyers and accurately describe the product.

In some cases, multiple products are allowed to have the same or similar titles. For example, when you sell bulk products of the same model or specification, the titles may be similar. But in order to improve search engine rankings and attract more customers, it is best to try to create a unique title for each product to highlight its characteristics and value. This helps increase product visibility and sales opportunities.
