The optimal target audience is shown in the middle of this Target Audience Venn Diagram. Because they fit all three personas, this is the primary target audience. Anyone who fits two personas, such as a healthconscious mom, would be your secondary optimal target audience. Even if some people only meet one persona, they are still a target audience and must be addressed. One advantage of social marketing is that it allows for unprecedented message adaptation based on the targeted group.
