The invention relates to the technical field of computers, and discloses a user behavior data ranking method and device. The user behavior data ranking method includes that: a terminal acquires a maximum value and a minimum value included in each first use behavior data set corresponding to a target data type in a first time period from a database server, and acquires at least one piece of second user behavior data corresponding to the target data type in a second time period; the terminal determines a maximum value and a minimum value of each second user behavior data set; the terminal determines a second user behavior data set to which the at least one piece of second user behavior data belongs; the terminal determines a position of the at least one piece of second user behavior data in all the second user behavior data; and the terminal performs a display operation according to the position of the at least one piece of second user behavior data in all the second user behavior data. The user behavior data ranking method and device can solve the problem that the amount of computation is large, real-time ranking cannot be achieved, and the intuition cannot be achieved in the prior art.
