Community practitioners must leverage a variety of tools in order to promote and advocate for social change. Social media are relatively innovative tools for informing and mobilizing communities in an advocacy effort. As part of a coordinated effort, social media align well with the principles of community psychology by enabling individuals to contribute to participatory dialogue about social issues, collaborate on change efforts, and establish a sense of community. These tools can enhance supporters’ advocacy engagement and can help sustain efforts in the midst of inevitable challenges. However, social media alone are not sufficient for promoting social change, but should be used to enhance traditional organizing strategies. In addition to synthesizing literature across empirical and practitioner (e.g., communication consultants) sources, real-world examples are provided to illustrate how social media can enhance advocacy efforts. This article presents findings from an extensive literature review to serve as a resource for community practitioners on ways to enhance advocacy efforts with social media.
