Alibaba is the largest commercial platform in China, which includes buyers and sellers from most industries in China. Generally, buyers can contact the seller directly when they choose their favorite items, but the seller cannot contact the buyer directly. If sellers want to find buyers quickly, effectively and accurately on the platform of Alibaba, they must design the keywords and products of their stores, so that their products can rank as high as possible on the home page to attract buyers' attention. If the other party is interested, the system will generate an inquiry so that you can see the other party's information and get in touch.
