Systems and methods for controlling in which order elements of a set of displayable content are transferred via an online connection are disclosed. Exemplary implementations may receive a client-initiated request from a client computing platform for a webpage, and, responsive to receipt of the client-initiated request, transfer to the client computing platform a set of information that includes displayable content, a set of content locations, and executable content configured to be executed by the client computing platform. Execution of the executable content may include transmitting, from the client computing platform, one or more executable-initiated requests for one or more transfers of elements of displayable content to the client computing platform. An executable-initiated request may be initiated by the executable content. Upon completion of the requested transfers, the transferred elements are presented on the client computing platform.
