The application discloses an information push method and device. One embodiment of the method comprises the following steps of acquiring information search data of a terminal, wherein the information search data comprises data, correlated with a search application, on the terminal within set time; extracting information from the information search data to obtain search characteristic word set and a search target word set, wherein a search characteristic word is a search word inputted into the search application, a search target word is a key word extracted from search data obtained from the search characteristic word through the search application; determining a matching relation by matching the search characteristic word in the search characteristic word set with the search target word in the search target word set; and pushing the push information of the search target word corresponding to the search characteristic word to the terminal according to the matching relation, wherein the push information is used for explaining the search target word. With the embodiment, the correctness and the real-time performance of the push information are improved.
