An Interest Segmentation task segments your constituents into different user sets who have selected similar interests, or opted out of the interests, during the registration process or while interacting with your site . You can select to include multiple interests and also specify if the task results group should include all constituents who match any of the interests or only the subset of constituents who have all selected interests.
When you create your new task, you will give it a name that displays for the task in the Task List and the group name in the To Do List. You may want to provide a unique name and description in case you run multiple tasks of this type for different interests and combinations of interests. You can set the task to run on a daily or weekly basis.
