An influencer is someone that has the power to influence the thoughts and opinions of a large audience. This is typically someone on Social Media with a large, highly engaged following. This kind of person is highly valuable to advertisers and to marketers alike as they have the ability to sway purchasing decisions, increase brand awareness, and even set trends and define what is “cool.” You can earn a huge amount as an influencer, but that’s not the only reason to aim for this target.
