Patent ID: 8510651

Claim:
A non-transitory computer-readable medium embodying a program executable in a computing device, the program comprising: code that presents, in conjunction with presentation of a network page in a first graphical pane, a graphical interface to edit a layout of the network page in at least one separate graphical pane; code that enables user-specification of at least one page element of a version of the network page designed in the graphical interface to be evaluated as part of a trial experiment; code that enables user-specification of at least one metric to be generated responsive to interactions with at least one version of the network page, the at least one version of the network page including the version of the network page designed in the graphical interface; and code that enables user-specification of at least one sample class of visiting users requesting access to the network page that is to be subject to the trial experiment; code that receives a user-selection of parameters to the trial experiment of the at least one version of the network page in the at least one separate graphical pane, wherein in the trial experiment, the version of the network page designed in the at least one separate graphical pane is administered to a first sample class of users, wherein the parameters to the trial experiment comprise at least one of a date to initiate the trial experiment, a date to terminate the trial experiment, a percentage of visiting users to assign to the at least one sample class of visiting users; a designation of a class of visiting users to assign to the at least one sample class of visiting users; and a designation of a failsafe that automatically terminates the trial experiment; and code that tracks the at least one metric for the at least one version of the network page designed in the at least one separate graphical pane based on interactions with the at least one sample class of visiting users.
