The invention discloses a method and device for information push, a client side and a server. The method includes the steps that configuration information of information to be pushed is acquired by acquiring and analyzing an information configuration file; according to the configuration information, feature information of the information to be pushed is acquired, and the exhibition position of an exhibition control corresponding to the information to be pushed on an application program operation interface is acquired as well; when an operation event corresponding to an application program is monitored, the exhibition control is displayed on the application program operation interface. The method for pushing the information to be pushed has the advantages that information push and the application program are separated and the configuration efficiency of information push and convenience for information push configuration change are improved; furthermore, the maintenance cost of information push is reduced and a large amount of manpower and a large number of material resources are saved.
