Performance reports are only shown if the rule has a Primary goal (and optionally, one or more secondary goals) associated with it. If you click the New Performance link for a rule with no goals, a message informs that the rule has no goals associated with it.  

If you're creating an A/B test and do not associate a Primary goal with it, you will not receive any performance data or statistical significance information. 

Impact of editing a goal on performance reports

If you want to edit a goal that is currently being used in active rules, you have two options:

• You can choose to edit the original goal. In this case, the performance report for the goal after the edit date will be based on the new definition of the goal. When you view performance report for a rule that has an edited goal associated to it, the original goal is displayed in the Legacy goal tab and the new (edited) goal is shown in the Goals tab. 
• You can choose to create a copy of the rule and then edit the copy (duplicate) rule as needed. In this case, the edited goal will be tracked as a new goal after it is published. 

If you want to edit a goal that is not being used in active rules, the performance report for the goal after the edit date will be based on the new definition of the goal.

Impact of deleting a goal from Goal Library

If you attempt to delete a goal from Goal Library, a warning message appears. The message provides details of the rules currently using the goal, with link to the rule details page for more information. Note that deleting a goal also removes all the performance report information associated with the goal.
