It helps companies build their brand and loyalty based on consumers‘ trust in someone they know and admire. Given this fact the purpose of this study is to define the theoretical basis of the impact of influencer marketing on consumer lifestyles. This includes an analysis of the perception of influencer marketing by consumers in relation to consumer lifestyles by means of a questionnaire survey focused on Slovak consumers aged 15 and above. The research sample comprises 410 respondents. Based on the results of the questionnaire survey and the verification of statistical hypotheses, it is clear that influencer marketing has a significant impact on Slovak consumer lifestyles (especially on consumers younger than 35). Finally, the effects of influencer marketing on consumer lifestyles are highlighted, and proposals are put forward for its efficient implementation within companies.
