Experimentation action definitions can each define a different computer action. Execution rules can govern an execution order of the different computer actions. A set of computer-readable preference levels of a current user profile can be received. Each of the preference levels can be for a corresponding one of the executed actions being executed for the current user profile. The preference levels can correspond to user interface responses to the execution of the executed actions. One of the executed actions can be selected as a follow-up action to take for a subsequent user profile. The selecting can include selecting the follow-up action from among a plurality of available actions such as the executed actions. In response to the selection, execution of the selected follow-up action for a subsequent user profile can be requested.
