Accurately analyze what information customers need. When a mother enters the store, the shopping guide will have a topic as long as she talks about her children. However, at present, marketers in many stores are eager to sell their products and forget about precision marketing. If the maternal and child store has registered the birth time of the child when recording the consumer information, then it is necessary to know how to use these data. The store manager can call customers with a one-month-old baby in advance. "The baby is three months old today and will be vaccinated in a few days. Children may have a fever after vaccination. You can prepare some glucose or probiotics to alleviate the symptoms of fever or diarrhea. " When you take the initiative to inform customers, mom may think that the product you suggested is necessary.
