This study aimed to analyze the status of major countries’ online national language dissemination for overseas learners. This was done by the representative national organizations founded with governmental support. The study comparatively analyzed the dissemination status of the representative organizations of other countries and representative Korean organizations for Korean language education. The results of the comparative analysis of the major websites of the seven countries investigated in this study revealed the following characteristics. First, the websites were categorized into integrated single and divided dual websites according to their characteristics. Second, the language and cultural content varied depending on whether the websites provided information on offline education service or not. Third, there was a major difference in the number of service languages available on each website. Further, it was distinguished by its strength in providing a variety of specialized learning materials including self-learning modules, video clips, webtoons (internet-based comics), and study materials. However, it was also revealed that further improvements were required in promoting offline education programs and introducing the Test of Proficiency in Korean (TOPIK). This study is valuable because the analysis results suggest implications for improvements to be made to the website of the Korean language for better dissemination.
