The dynamics of the development of tourism sector is reflected, among other things, in the fact that an increasing number of tourists choose an offer based on online reviews. Although it is true that due to the intensive development of communication via the Internet, online reviews are one of the dominant sources of information, their level of perceived usefulness may differ. The aim of the research is to examine the extent to which textual comments, photos and ratings of tourist offers determine the usefulness of online reviews. In order to analyze the results, we used exploratory factor analysis. Moreover, by using regression analysis, it was confirmed that usefulness affects the level of trust in online reviews, as well as that trust has implications for the intention to purchase a tourist offer. Finally, we came to conclusions that may have numerous implications for the decisions of marketing managers in the field of tourism.

Using websites for commercial purposes has been noticeable in numerous areas in recent years, including the organic food market, among others. The era of digitalization has implied that an increasing number of consumers form their views on organic food based on information that is marketed via websites, instead of going to traditional stores. In accordance with that, the aim of the paper is to examine whether the quality of a website, measured by its usability, design and the quality of information, affects consumers' cognitive and affective attitudes towards organic products. In this paper, exploratory factor analysis is carried out along with multiple regression analysis. The research results indicate that, in the organic food sector, it is very important to have a website which is both usable and visually appealing, simultaneously containing quality and updated information, which all can greatly influence the formation of users' attitudes towards organic food, their attitudes being made of the rational emotional dimensions as well. The contribution of this research study is particularly significant bearing in mind the fact that attitudes towards organic food are mostly examined in a traditional environment, not so much in an online environment.
