After the first trial sale, see which products are selling well and increase the investment in those products.
There is no need to increase inventory or ship large quantities of items as soon as other Sellers are growing. First, check the market's response to the products. Depending on the product, most sellers usually start with a few small boxes or single pallet by courier or air freight. After that, once you confirm that the goods are selling well, take advantage of transport by ship, which is larger and more cost effective.
You can also re-prioritize listings based on best-selling product information.
For example, during the holiday season, you may prioritize the best-selling items and update the listing information such as translations, images and videos. When planning a sale or promotion, you can also target only the products that are selling well.
It's important to always review the feedback of the products you sell and improve them with each listing. Try all sorts of things, from tweaking the product listing and ad copy to even adding new product variations.
