Social media is rapidly and dramatically transforming the communication landscape. They are purported to provide reputational benefits by promoting transparency and enhancing possibilities for stakeholder engagement. However, they also present reputational risks by exposing organizations to new types of crises, stakeholder criticism, and digital activism. Corporate Communication through Social Media takes a grounded approach in bringing together perspectives from communication and management and from scholarship and practice. It helps the reader to make sense of digitalization in corporate communication and its consequences for organization–stakeholder relationships, trust, engagement, leadership, and reputation. Covering a wide spectrum of topics such as branding, consumer engagement, employee relations, crisis communication, corporate responsibility and sustainability, and the return on investment (ROI), the book maps key changes in the evolving communication landscape, with an understanding of the strategic benefits and challenges for corporate reputation.
