Tom McClintock gave a presentation on calculating the return on investment (ROI) of social media. He discussed two viewpoints - that ROI from social media cannot be calculated since much of its value is indirect, and that ROI can and must be calculated. He provided examples of companies that successfully measured ROI. McClintock also outlined new approaches to calculating ROI from social media, such as measuring retention, research, and sentiment. He concluded by discussing tools and case studies for measuring social media ROI.
