Social media jobs focus on using online platforms for marketing, data acquisition, or communication with a target audience. The qualifications that you need to start a career in this field include an understanding of marketing as well as experience and skills using online platforms. Influencers only need a large social media following and content production skills, while a manager may be expected to have a postsecondary degree in marketing, public relations, or advertising. Some community colleges offer a certificate in social media marketing. Most employers expect applicants to be active on social media and have a portfolio of past work.
