Abstract: Proposed is a method for product recommendation by a server. The method may include receiving a gift recommendation request from a first user terminal for a second user, checking available basic information of the second user, and determining a first recommendation information based on the basic information, wherein the first recommendation information comprises a first recommendation reason and at least one product related to the first recommendation reason. The method may also include determining a second recommendation information not based on the basic information, wherein the second recommendation information comprises a second recommendation reason and at least one product related to the second recommendation reason. The method may further include providing recommendation information comprising the first and second recommendation information to the first user terminal. The first recommendation information may be prioritized for display over the second recommendation information.
