The invention discloses a connection rate detection method and device, and belongs to the field of network communication. The method comprises that coverage of an address link in a pre-click area is detected; if coverage of the address link in the pre-click area is detected, a network address of a server corresponding to the address link covered in the pre-click area is acquired; and connection rate between a terminal and the server corresponding to the address link is detected according to the acquired network address of the server corresponding to the address link. A problem of wastage of network bandwidth caused by the fact that a video link cannot be played after being opened by a user or playing rate is not smooth is solved via acquisition of the network address of the server corresponding to the address link covered in the pre-click area and detection of connection rate between the terminal and the server corresponding to the address link according to the acquired the network address of the server corresponding to the address link so that objectives of saving hardware and network resources and enhancing detection efficiency and detection performance are achieved.
