Southwest Airlines launched its blog "Nuts About Southwest" in 2006 to provide customers a look inside the company's culture and operations. The blog now serves as a virtual focus group, place to share news and stories, and platform for employees to connect with customers. It features over 30 employee bloggers and was named the best blog by PR News in 2007 and 2008. Southwest also communicates with customers through social media like Twitter, YouTube, and Facebook to stay connected with changing technologies and reach broader audiences. The company measures engagement across channels and uses case studies to understand how content impacts search optimization and sentiment.
