The development of the Internet, and new technologies as an indicator of changing living conditions, due to the faster transfer of information and high networking, which amplifies the effects of globalization, have a strong impact on tourism trends. The main role of new technologies as tourism promoters for the purpose of destination development is to promote the tourist offer and products that are presented to the user in a modern and accessible way. The development of technology has contributed to innovations in the market, destinations are adapting to trends and requirements of tourists. Mobile marketing certainly plays a key role in the development of rural tourism. Mobile marketing implies the implementation of marketing activities using mobile devices and technologies. The great importance of the role of mobile marketing in the development of rural tourism is noticed, because it is very important to carry out marketing activities in order to attract visitors, and thus increase earnings. The Republic of Croatia still has „room for improvement“ in terms of the proper use of mobile marketing for the development of rural tourism. It is not enough to use only websites, and various social networks, because this way of marketing has long been overrepresented, so it is necessary to include activities that no one has introduced before, to be unique. The only recommendation that would encourage the progress of the Republic of Croatia in the use of mobile marketing is to emphasize the uniqueness, quality, interesting story, to include real people in the campaign, as is the case in Switzerland. On October 25, 2020, a research was conducted, ie a survey, related to the topic of the role of mobile marketing in the development of rural tourism. The survey was attended by 50 respondents, and it is intended to obtain data on the importance of mobile marketing in the development of rural tourism. The survey conducted consists of the following hypotheses, namely that the respondents are familiar with the concept of mobile marketing, and that mobile marketing is important in the development of rural tourism. The research confirmed these two hypotheses.
