As social media continues to grow, so does the need to have a strong online presence that exhibits a unique personal brand. However, with social media platforms ranging from Twitter to Instagram to LinkedIn, it is a challenge for Millennials to know how to build a personal brand that is appropriate for all potential audiences. More than just friends and family are viewing our social media profiles; it is common practice for potential employers too and it can be difficult to cater our social media for both. This thesis looks at how personal branding has evolved with the rapid expansion of social media and the relationship between the two. It also looks at the importance of personal branding and best/worst practices for social media. Although there is an emphasis of professional networking platforms in my primary research, I also discuss how social media affects our personal, along with our professional, relationships. There is also a focus on the types of perceptions people make about someone’s personal brand based off of what they see on social media. To better understand people’s perceptions of social media as it relates to personal branding, I conducted interviews with job recruiters and administered a survey, which tested recommendations collected from the first interviews.
