Place-based social media can be used to help locations engage customers and brands engage audiences. Understanding how to optimize that engagement requires an awareness of the end user’s availability and ability to participate as well as an appreciation of the environment for their engagement, the Digital Out of Home network’s capabilities and the stakeholder’s objectives. This paper describes the stages of user engagement that map to three types of place-based social media engagement; Passive, Active and Interactive, each in turn mapping to distinct social media applications that can optimize the engagement strategy for locations (retail, hospitality, fitness, health care etc) and brands.
