Students looking for a career should know what their “online footprint” looks like and how they come across professionally. A simple Google search will show you what an employer will see (and a potential employer WILL look for you on the internet). If you have social media profiles, they will appear in a Google search unless privacy settings prevent it.
If you do not already have a social media profile, I don’t suggest creating one for the purpose of a job search…UNLESS the jobs you are seeking are with companies who appear to value social media (e.g., a radio station, a PR firm, or Google are going to want to see that you have a good grasp on social media outlets!). More companies these days want to see a social media presence, because that is the medium they use for a lot of their marketing.
LinkedIn is a different sort of social media platform – much more professional than Facebook. Since most jobs are acquired through networking, I DO suggest creating and maintaining a professional LinkedIn page for anyone looking for a career.
