A method of advertising selects an attribute value for a test. The attribute value is for representing a relationship between a user activity and one or more of a user segment, a publisher group, and an ad category. The method optionally constructs a test case that includes the attribute value and one or more of: the user segment, the publisher group, and the ad category. The method selectively places the test case in an inventory location of the publisher group, presents the test case to the user segment, and monitors the status of the attribute value based on user activity. The method of some embodiments tracks a confidence metric for measuring the reliability of the attribute value. If, for instance, the confidence metric is below a predetermined threshold, then the method performs the test. Alternatively, or in conjunction with the foregoing, the method applies a set of rules for determining the importance of the test. If the importance of the test according to the set of rules is low, then the method advantageously forgoes the test.
