This paper employs Netnography to discuss what types of tactics the amateur individual employs onto online video sharing websites such as YouTube and how they present themselves to attract their online audiences. The results construct a taxonomy of individual impression management tactics: imitating, mystifying, kuso, self-promotion and gender-switching. Qualitative data analysis suggests while participants manage their individual online impression, engaging in different tactics or tactics in combination designed to create an ideal image. They fully observe, imitate, evaluate and adopt various tactics to count whether the ideal image should be fulfilled or not.
