The consumer decision making process is becoming less complicated, as consumers are turning more and more to social media and peers for reviews and suggestions of new products to purchase. Changes in purchasing trends, along with other external factors, have created a perfect environment for influencer marketing to become more effective for brands than traditional marketing strategies (including television, print, email and radio advertising)—by reaching the right target market with easier ways to track conversion rates and other returns on investment. This thesis looks at the factors that go in to influencer marketing, including why brands utilize this strategy—in terms of budget, returns on investment and best practices for finding the perfect influencers. It also looks at influencer marketing from the view of the influencers themselves. This thesis looks at the spectrum of influence and the motivation and goals of each level—from macro-influencers to micro-influencers and brand advocates. To better understand the research presented in this thesis, a case study of a successful brand, analysis of influencers and a creative project are all presented.
