The Multi-Channel Network (MCN) business, which works with social media/streaming platforms to offer strategic assistance to a group of one-person creators is recently flourishing. As is well known, it has become a very common practice for corporations/individuals to utilize those one-person media for various marketing purposes as well. Unfortunately, however, despite its ever-increasing importance, many marketers still seem to rely too much on their own experience or intuition rather than scientific findings or knowledge when they have to choose one-person media. This is problematic since selecting the right one-person media is essential to increase the effectiveness of a marketing campaign. In this regard, the current study explored relative importance and priorities of many different elements in selecting one-person media using the Analytic Hierarchy Process (AHP) method. The results showed first that the primary evaluation factors consisted of 7 factors (user factor, content factor, economic factor, media reputation, management, fit and flexibility). Subsequently, the secondary evaluation elements were found to consist of 18 factors (reach, exposure frequency, page view, number of visitors, CPM, production cost, content quality, content differentiation, content creativity, channel awareness, channel reliability, channel favorability, product fit, target fit, interactivity, viewer service, MCN reputation, and expertise of the advertising practitioners). Meanwhile, content factor was the most important among the primary evaluation elements, followed by user factor, fit, media reputation, economic factors, flexibility and management. In addition, the analysis of priorities based on the overall weight demonstrated that content creativity, content differentiation, and page view were important factors in choosing one-person media.
