The Google Display Network (GDN) has a growing list of ways to reach potential customers. To do so, we can target audiences (in-market audiences, affinity audiences, demographics, etc.) or content (topics, keywords, etc.). To take that a step further, we can layer different types of targeting to truly pinpoint a subset of users or we can simply observe how different types of people interact with our ads. This is where the very important distinction between targeting settings come into play.
