For an example of how to use Content Targeting, consider the target type of Member Location. A multi-national company might have Members across three continents—North America, Europe and Asia. Continents are the highest level of this hierarchy, and are represented with green boxes. In Europe, offices are in the cities of London and Amsterdam, with cities being the lowest level of the hierarchy represented by blue boxes. In Asia, the countries of China, Japan and Singapore have offices, but China has offices in two cities—Shanghai and Beijing.
In the United States, four cities have offices, but two of those are in the State of California. Canada and Mexico also have offices, including offices in both Toronto and Vancouver for Canada. In this scenario, Members will only be selecting from the lowest level of the hierarchy represented by the blue box, which is the most specific level. Since a Member can only select at the blue box level, they can say they are located in London, Seattle or New York, but they cannot select California, China or Europe. So even though a level may have a city and a state, it is not possible for a Member to choose the wrong level in the hierarchy for their location. This scenario illustrates how hierarchies can be as flexible as you need them to be.
