As social media have become a topic of interest for many industries,
it is important to understand how social media data can be
harvested for decision making at the industry level. Currently, the
majority of social media studies focus on individual companies
or organizations. There are few studies performing social media
competitive analysis on the leading companies in an industry in
a systemic way. As an exploratory study, this case study made a
contribution by using text mining to perform competitive analysis
for the user-generated data on Twitter and Facebook in three major
pizza chains. Results from the text mining and social media competitive
analysis show that these pizza chains actively engaged their
customers in social media such as Twitter and Facebook. They used
the social media not only to promote their services, but also to bond
with their customers. Findings from this study suggest that social
media plays an important role in sustaining a positive relationship
with customers.
