Internet is a medium that has brought major changes in various fields, such as communications, commerce, entertainment, etc. However, the internet is not only a medium, it is also considered to have presented a new marketing paradigm, known as internet marketing. In relation to the traditional form of marketing, internet marketing is a superior form, especially when it comes to promotion. Internet marketing offers many advantages, such as the possibility of reaching more users, faster dissemination of information and news, and is at the same time cheaper. One can say freely that today internet marketing is essential for successful business operations and promotion of services and products that are offered. Therefore, the focus was on the analysis of promotion of tourist agency Mondo Travel via internet marketing. Analysing the official website and profiles on social networks, it can be concluded that the travel agency Mondo travel is making real efforts to achieve good promotion through internet marketing. In addition, the position on the Internet search engine is more than excellent, since the agency is presented in the first five results, which greatly contributes to the promotion itself. Although they have a good promotion, in the future the agency should make efforts to expand its profile to additional social networks, perhaps pay more attention to building a better Instagram profile, which would certainly contribute to the agency's promotion, while maintaining its place and becoming the leading agency on the Croatian market.
