The extent of the Tourism is increasingly linked to the development of information and communication technologies, especially the Internet and for a long time the online market is becoming a key aspect of its further development. Current technological development brings with it significant digitization of all processes and significantly affects how today's companies are entering and communicating on the online tourism market. Similarly, as a result of these changes, the significant change occurs in consumer behaviour, and across all age groups. With the development of these technologies, today's consumer is not only knowledgeable and more experienced, but is increasingly being constant online part of this market. The development of online tourism market is thus increasingly strongly linked with the growth of the total Internet population and currently also the one, that is using to the internet access the cellular infrastructure and equipment. The aim of disertation is to analyze the impact of the development of the internet as a global phenomenon of the last decade, and information and communication technologies on the tourism market, and to create a comprehensive look at this issue from tourism market perspective.

This study examines the personalization of shown travel destination visual images using professional photography upon travel motivations, feelings, and purchase intentions of consumers in the online environment. The research design was experimental and used data from a questionnaire via Qualtrics. A pilot test of the instrument was conducted. The final questionnaire contained 25 items. A total of 194 questionnaires were collected and participants were randomly assigned to one of four groups. Each group of 50 participants was exposed to a specific set of travel destination visual images. Further, several hypotheses related to the effects of personalization, professional photography toward travel motivation, emotion, and purchase intention were tested. The results indicated that: (1) travel motivation was affected by both personalization, and professional photography of travel destination visual image; (2) personalization had an influence on positive emotion, but professional photography did not; (3) it was expected that personalization would act as a “push” factor on travel motivation, and professional photography would influence the “pull” factor on travel motivation, but these two hypotheses were not supported; (4) travel motivation and emotion positively affected purchase intention, however this was only partially supported. Furthermore, the results of the present study implied that the “push – pull” travel motivation theory was considered not entirely separate. Practical recommendations are presented for online tourism marketers to enhance their service.

Information systems literature calls for websites providing a site architecture that is as close as possible to the mental model of the user. To assure that users will be satisfied, website designers need to be aware that users interpret elements offered on a website based on their physiological and psychological factors. Creating a compelling online experience for diverse groups of e-customers is a challenge and of utmost importance for a website's success. However, in the field of tourism literature that discriminates between requirements based on motivational or cognitive aspects of certain user-groups is scarce. Therefore, the hypothesis examined in this dissertation is that there are differences between a priori defined user-groups regarding their satisfaction with web 2.0 websites. Further, this research is aimed at not only taking the demand side into account but also the supply side by asking whether the supply side is aware of the increasing importance of web 2.0 contents and its potentials for information presentation and market research. To bring the project into a coherent framework three more aspects are tackled. First, due to the fact that there is no existing typology for travel-blogs this dissertation tries to fill this gap by means of a qualitative approach. Second, an alternative, more parsimonious measurement approach for website performance is proposed. Finally, a study on measuring emotional mental models, a topic which seems to be neglected in information systems literature as well as in the field of tourism, is included. In order to investigate all these issues nine empirical studies are conducted. The approaches used include online surveys, content analysis, and quasi-experimental design. For data analysis methods such as Partial Least Squares Structural Equation Modeling, Covariance Based Structural Equation Modeling, and Artificial Neural Network Analysis are applied. The results indicate that there are differences between a priori defined user groups regarding their satisfaction with web 2.0 websites. For instance, the influence of motivational factors on the importance of website features differs between travelers who seek relaxation and those who seek adventure. Moreover, the main drivers for value and satisfaction for a goal-directed search are content quality followed by usefulness. These effects are attenuated for the experiential search. The study focusing on communication modes suggests that for verbalizers content is most essential while for visualizers the most important aspect is design. A further study, investigating the influence of hotel guest reviews on customer hotel preferences, reveals that in certain instances the subjects' willingness to pay is significantly higher than their reference price. Additionally, the findings indicate that people who read consumer reviews online do not belong to only one homogeneous group but perceive the importance of review categories differently. Pertaining to the supply side findings show that managers in Austria, Germany, and Switzerland assess user generated content as highly important and that managers have a rather positive attitude towards negative reviews. However, there is evidence that hotels and museums are not seizing opportunities the Internet provides in terms of information presentation. Concerning the formative measurement developed for website performance cross validation proved that the index works well. The last study sheds light on measuring emotional models and gives insights into changes of users' emotional mental models before and after their visitation of a virtual world. The final chapter "Discussion and conclusions" critically discusses the results of the nine studies from a theoretical point of view, debates the approaches used and methods applied, and gives managerial implications and suggestions for future research.
