WHICH YOUTUBER SHOULD BE FOLLOWED? A COMPARISON BASED DELPHI-AHP-TOPSIS

With the development of technology, education activities also get their share from the rapid transformation. With social media platforms, it is now possible to access information from anywhere at any time. While the accuracy of every information in the virtual world is discussed, the information provided on platforms such as YouTube also has results related to the channel that transmits the information. Many videos are shared on YouTube in various fields (education, music, sports, comedy etc.). Education-based YouTube channels are also highly preferred among these channels. This study aims to identify and prioritize possible alternatives to identify how YouTube-based users decide on the YouTubers (Youtube channel owner) that they select and in order to be constantly improved. Comparison with a Delphi-AHP-TOPSIS based methodology is divided into 3 stages. The first stage is the Delphi Method, where basic performance factors and sub-factors are defined, synthesized and prioritized. The second stage is the use of AHP method to obtain the general performance index of the main factors and sub-factors. The third stage is the ranking of possible alternatives between TOPSIS technique and 10 YouTubers for continuous improvement of YouTube channels. As a result of the analyzes, the most important criteria in choosing YouTuber were tried to be determined and ideal solutions were presented in decision making.
