When combining keywords for AliExpress titles, you need to consider the following points:

First, the keywords should be consistent with the actual attributes of the product, highlighting the selling points and characteristics of the product.

Second, the keywords should have a high search volume and competition level to attract more target customers.

Finally, long-tail keywords should be used as much as possible to improve accuracy and ranking effects. In general, the best combination is to ensure the relevance of keywords to products, while meeting the requirements of search volume and competition level, and use long-tail keywords as much as possible to improve the effect.

The correct combination is necessary because a good keyword combination can increase the probability of a product being searched and the click-through rate. When formulating a keyword combination, you need to focus on the main selling points, features, brands, models, etc. of the product, and combine the industry's hot words and popular search keywords to build a fast and effective title. If you can formulate different title keyword combinations for different search engines and platforms, then your product will have more tension and exposure to attract more target customers. Therefore, for sellers, it is necessary to invest enough time and ingenuity to formulate the correct keyword combination to increase the exposure and sales ability of the product.
