Patent attributes
A machine may be configured to perform A/B testing on customized experiment units. For example, the machine receives a specification of an experiment unit that identifies a type of subject of an experiment for execution on a social networking service (SNS), and a value of the experiment unit. The machine generates, for the value of the experiment unit, tracking data that tracks user interactions by one or more users of the SNS, via one or more browsers, with content provided during an execution of the experiment. The machine generates, for the value of the experiment unit, metric data that measures an attribute associated with the experimental unit. The machine generates an experiment report based on the tracking data and the metric data. The machine causes a presentation of the experiment report in a user interface of a client device.
