On AliExpress, it is OK to add a trademark to the title, but you need to pay attention to the following points:

1. Respect intellectual property rights: If the trademark you use in the title is registered by someone else, you need to make sure that you have obtained the ownership or right to use the trademark. Otherwise, it may cause intellectual property disputes.

2. Comply with platform regulations: AliExpress allows the use of trademarks in titles, but requires that the titles should be true, accurate and not misleading to consumers. Please make sure that your title meets this requirement.

3. Concise and clear: The title should be concise and clear, and avoid being too long. A good title should be able to clearly convey the main features and advantages of the product, helping consumers to quickly identify and select the product.

4. Highlight product features: In the title, you can highlight the features and advantages of the product, such as material, color, size, scope of application, etc. In this way, consumers can understand the product more quickly and increase their willingness to buy.

In short, it is OK to add a trademark to the AliExpress title, but you need to ensure that it complies with intellectual property regulations and platform regulations, and is concise and clear to attract consumers.
