The strong cultural linkage between Ireland and North America now presents a unique opportunity for the Irish tourism sector via social media. There the industry can engage with existing and potential customers around the online presence of items of cultural interest that can influence the decision to visit (and revisit) Ireland and experience a wider range of attractions. The main objective of this study is to examine the role of social media in marketing Ireland as a destination to the North American market. Various quantitative and qualitative research methods were employed to obtain the perspectives of visitors and of key stakeholders regarding the effectiveness of social media in attracting these North American visitors (NAVs) to Ireland. Methods included online surveys of visitors and semi-structured, in-depth interviews with those responsible for implementing social media strategies in the Irish tourism sector. Furthermore, a Netnographic analysis of the key stakeholders’ social media strategies was carried out using the Nvivo 11(Ncapture) software. This approach generated a large amount of data that had to be analysed and coded so the emerging themes relevant to the main objective could be identified. This analysis revealed the potential for social media to transform Irish-North American tourism strategies for the various stakeholders. Nevertheless the analysis also particularly provides key insights into the knowledge and resource requirements of the Irish SMEs operating in this sector. One of the conclusions of this study is that the enormous potential of social media to provide a cost-effective strategy for Irish SMEs can only be realised if issues relating to knowledge and resource limitations are properly addressed. In an effort to address the challenges and opportunities for growth posed by social media for Irish tourism SMEs, this study proposes adaptations of existing theoretical models such as the Ansoff and BCG matrices. This study’s innovation includes a proposed key performance indicator (KPI) framework that can be applied as a cost effective social media strategy. The study demonstrates how the proposed strategy can be put into practice and become of practical benefit to the Irish SMEs who wish to move from a position as peripheral agents. This can happen through implementing such a technologically-enabled market strategy and using a network of contacts freely available through social media platforms.
