In 2015, influencer marketing was just a buzzword running around the marketing world. At that time, companies (mostly online shops, start-ups and SMEs) tried influencer marketing with such a simple concept in mind: “Paying famous girls (and guys) on social media for some tweets (posts)”. Now, in 2017, it has become “a business” according to Forbes and a marketing strategy implemented by huge brands in various industries (e.g. Daniel Wellington, Mercedes-Benz, Schwarzkopf Professional, etc.) This post will show you the definition of influencer marketing so far and how it will be the next big thing of digital marketing.
