Comparing to larger businesses, SMEs face more barriers in their marketing operations since they have a lower amount of financial resources and assets. But the emergence of social media platforms has provided many chances for them to overcome these barriers by enabling them to do marketing and promotion activities. Although these social media channels are easy to access by each of their users, awareness, perceptions, capabilities of SMEs might differ when using these platforms. In this regard, this research aims to analyze and find out whether social media usage differs among SMEs regarding their age and size. In parallel with this purpose, the researchers used an online questionnaire to collect data from 454 Czech SMEs. These SMEs were selected by applying a random sampling method and then an online questionnaire was directed to the respondents who were owners and managers of these enterprises. To analyze the data, the researchers performed an Independent T-test in SPSS statistical program. According to the results, social media usage does not differ between smaller-larger and younger-older SMEs. The reasons for these similarities among SMEs might stem from the industry that they operate, the cost of social media usage, and the age of younger firms’ executives. Nonexistence of the differences among analyzed Czech SMEs makes this paper differ from other studies. Some policy implementations are also offered by the researchers to increase awareness, skills, and usage of social media platforms by SMEs.
