A system and method for displaying a user interface may include an examination and/or elimination of positional bias of interactive categories in order to drive user engagement. A method or system configured to execute the method on a user interface may include creating a first arrangement of categories. The arrangement can be shown on a user device to one or more users a selected number of times. The users' interactions with the categories in the interface may be recorded. The method may further include creating a second arrangement, which is different from the first arrangement, and this second arrangement may be shown to the users the selected number of times and the users' interactions with the second arrangement may be recorded. Based on the frequency of user interactions with the first and second arrangement, a ranked set of the categories may be created and displayed to users.
