This document summarizes research into whether B2B companies can successfully use social media for marketing goals. It discusses definitions of social media, types of social media sites, interviews with experts on the topic, considerations for use, examples of both good practices from Novo Nordisk and bad practices from Nestle. Key takeaways are that social media can influence many people if done through a well-known brand, companies must allocate resources and communicate honestly while accepting potential loss of control, and quantitative and qualitative measurements are both important for defining success.
