he Croatian Mountain Rescue Service is a non-profit organisation, that was proclaimed as the „Best Communicator of the Year“ by the prestigious Croatian Association of Public Relations in 2016. The research of this paper was inspired by this award. Moreover, the main purpose for this analysis is to determine how HGSS conducts a successful communication strategy via social networks. The time period selected for analysis covers the entire year of 2016.on social networks, Facebook and Twitter. During the research, a total of 685 entries were posted on HGSS social networks, 476 of which are on Facebook and the remaining 209 on Twitter. For the purposes of data analysis, special categorisation of data was created which was the foundation for social network research. The data parameters were identical on both social network platforms, Facebook and Twitter. The elements of the categorisation included: the date of publication, the type of publication, the number of likes, the number of shares, the topic of publication, the relation between the publications and the used language. The data was then processed through a quantitative and qualitative approach of content analysis. The quantitative analysis included the specific statistics of the research which revealed the peak period for the highest concentration of publications and followers engagement. The publications with most likes were selected for qualitative content analysis that further extends the understanding of how HGSS communicates via social networks. Research questions were the main foundation of writing this thesis, whose responses led to some specific findings and conclusions. Content analysis of social networks of HGSS shows that 72% of publications were identical on both social networks. Preferred style of communication of HGSS is a combination of text and hyperlinks that lead to their official site where readers can find more details about the announcement. On an annual level, they communicated a total of 225 days on Facebook and 141 days on Twitter. During the winter and summer season, they increased their activity on social networks and used English as the official language in campaigns that were tourist- focused.
