Companies often discuss “word of mouth,” but how often and in what ways do consumers discuss their experiences? We surveyed 6,000 US consumers to find out. It turns out that the most common communication about good and bad experiences occurs between friends via email, phone, or in person. While few consumers share their experiences directly with the companies that pleased or displeased them, far fewer shared those experiences via social media channels such as Facebook, Twitter, and 3rd party ratings sites. Our analysis also uncovered differences by age, income, ethnicity, and educational levels. We analyzed the customer bases of more than 140 companies and discovered that Days Inn, E*Trade, and Apple were the most susceptible to negative feedback via Facebook. Days Inn, Courtyard By Marriott, and Hyatt are the most susceptible via Twitter.
