In conjunction with technological development, digital marketing has become a common course of action for marketers to discover potential consumers. A digital form of marketing is personalized marketing, where companies tailor advertising on the internet based on consumer preferences. By storing personal data from social media and websites, it becomes possible for companies to identify potential consumers. Generation-Z has grown up among digital platforms that offer personalized marketing. This thesis will therefore examine when Generation-Z experiences that personalized marketing transitions from being useful to infringing on the individual integrity. The research design used for the empirical data in the study was semi-structured interviews on Generation-Z between the ages of 8-24. During the interviews, it emerged that all respondents felt influenced by individualized marketing. They felt that personalized marketing could infringe on integrity but also be useful when needed. The results of the study show that the risk of collecting personal data like religious opinions, sexual preferences, political stances and audio tracking smartphones, is that trust in the company decreases among Generation-Z. The advantage of personalized marketing is that it satisfies the needs of the targeted audience in question. Generation-Z prefer ads that suit their preferences rather than having inconsequential advertising and are willing to exchange a small amount of personal information for tailored ads in return. Consequently, personalized marketing has a major impact on the internet experience among Generation-Z.
