[eng] Thanks to the development of technologies, the rise of social networks, and the continuous growth
of the tourism sector in Spain, companies in the tourism sector now incorporate new marketing
techniques into their business strategy. The aim of this is to improve the effectiveness of their
traditional advertising campaigns and to offer users advertising adapted to their needs and specific
preferences, with the design based on personal data obtained from social networks. These
personalised communication techniques can cause certain users concern around levels of
intrusiveness, and concern for privacy, due to the lack of knowledge of the use and collection of
their data, thus having an impact on the acceptance of personalised tourist advertisements on
social networks. In this study, the acceptance of personalised advertisements is evaluated by
studying attitudes and responses towards personalised advertisements, as well as the incorporated
concerns about privacy. The study also considers concerns based on control and knowledge of
the management and collection of personal data of the user at whom the personalised tourism
advertisement is aimed. The study concludes that companies in the tourism sector should target
their advertising to specific groups of users who, by their own choice, have an interest in being
part of a community related to tourism destinations or services. Also, they should manage the
personal data obtained in a clear and transparent way, to increase both the users’ control and sense
of security.
