The purpose of the study is to investigate how men and women experience personalized advertising, whether it affects the purchase decision and whether there are differences between men and women. A qualitative method has been used with the help of structured interviews within a delimitation of the Stockholm area. The theories used in this study consisted of the AIDA model, Customer Relationship Management (CRM), Relationship Marketing (RM), Customization and Personalization and Consumer Culture Theory. Results of the study show that there are clear differences in how men and women experience Instagram. The main difference is that women have a more positive view of personalized advertising, which leads to actual purchases to a greater extent than men. The men in the study, on the other hand, show that it is negative to individualized advertising to a greater extent.
