Use the platform's own search function to analyze the hot demand and potential demand of buyers. Basically, every cross-border e-commerce platform has a search box, through which demand can be judged. Take AliExpress as an example. When you open the AliExpress buyer page, many keywords will be displayed under the search box, such as mechanical keyboard, camera drone, women's ring, cat's eye sunglasses, 3d printer and so on. When the page is refreshed, the text will be different every time. These words are commonly known as hot keywords, and you can know which products are in great demand abroad through hot keywords.
