Abstract

The present invention relates to an advertisement providing system that takes advantage of the comment function of an SNS to expand Internet advertising, such as affiliate advertising, between members. Upon receiving a predetermined notification from an advertiser server, an SNS site control unit identifies a first user identifier associated with a second user identifier included in the notification and transmits, as content data, comment data including user information pertaining to a user of a second communication terminal and link information for a commercial website to a first communication terminal to which is allocated the identified first user identifier.

1 . A server, comprising:
 a user management database storing a first user identifier allocated to a first user in association with a second user identifier allocated to a second user;   a control unit causing a display unit of a first communication terminal used by the first user to display content data by transmitting the content data to the first communication terminal;   a reception unit receiving a performance notification that includes the second user identifier when a reward applicable process is executed by the second user in a predetermined service provided by an external server; and   a performance reward control unit granting a first performance reward to the second user in response to reception of the performance notification by the reception unit,   wherein the control unit transmits comment data as the content data to the first communication terminal when the reception unit received the performance notification, and the comment data includes link information for connecting to the predetermined service.   
     
     
         2 . The server according to  claim 1 , wherein the control unit transmits the comment data as the content data to the first communication terminal in response to an acceptance from the second user. 
     
     
         3 . The server according to  claim 1 , wherein the performance reward control unit further grants a second performance reward to the second user when a predetermined condition is satisfied. 
     
     
         4 . The server according to  claim 3 , wherein the predetermined condition is that the number of users who executed the reward applicable process in the predetermined service has reached a predetermined number. 
     
     
         5 . The server according to  claim 3 , wherein the predetermined condition is that the first communication terminal has connected to the predetermined service based on the link information included in the comment data transmitted to the first communication terminal and the first user has executed the reward applicable process in the predetermined service. 
     
     
         6 . The server according to  claim 1 , wherein the comment data is displayed in a comment display region of a page allocated to the first user. 
     
     
         7 . A communication terminal that connects to a server, comprising:
 a communication unit transmitting, to the server, a first user identifier allocated to a first user, and receiving content data from the server; and   a display unit displaying the content data,   wherein the communication unit receives, from the server, comment data as the content data when a second user executed a reward applicable process in a service provided by an external server, the second user is allocated a second user identifier that is associated with the first user identifier, and the comment data includes link information for connecting to the predetermined service.   
     
     
         8 . The communication terminal according to  claim 7 , wherein the server grants a first performance reward to the second user when the second user executed the reward applicable process. 
     
     
         9 . A method of providing an advertisement to a communication terminal that connects to a server, comprising:
 transmitting, to the server, a first user identifier allocated to a first user;   receiving content data from the server; and   displaying the content data;   wherein, in the receiving the content data, comment data is received as the content data from the server when a second user executed a reward applicable process in a service provided by an external server, the second user is allocated a second user identifier that is associated with the first user identifier, and the comment data includes link information for connecting to the predetermined service.
