A long tail information subscribing method is provided. The method includes receiving a to-be-subscribed long tail information type from a client-side, and determining whether an information content matches the long tail information type. The method also includes, when it is determined that an information content matches the long tail information type, sending a long tail information alert message to the client-side to cause the client-side to update an alert display based on the long tail information alert message. Further, the method includes receiving a trigger request message corresponding to the alert display from the client-side, and sending long tail information content corresponding to the trigger request message to the client-side. The information distribution efficiency is thus substantially improved.
