Abstract: Marketing and selling of products to different foreign ethnic groups in Finland were explored and analyzed in this thesis using the qualitative research method by selecting a random sample of individuals both males and females from different minorities living in Finland. Nvivo software was then used to code, analyze and visualize to obtain a deep insight of this sample of foreigners who have lived in Finland over three years in terms of marketing and ads preferences such as the languages, designs, color of these ads and also the impact of traditions and culture on respondent’s preferences in following ads. After an intensive screening and examining of all respondent's answers to qualitative survey questions and coding, the author concluded that the Finnish companies should add some other languages to their ads especially on social media sites, train and employ more foreign workers from ethnic groups living in Finland since they know the traditions, culture, and preferences of their ethnic groups and that will increase customers. There was a noticeable difference in the source of advertisement channels preferred by respondents. Ads in social media were highly preferred over TV, newspaper ads. There was not a noticeable difference in ad preferences in terms of the number of years the respondents lived in Finland as the majority in this qualitative research shared the same concepts of having ads in some other languages besides the Finnish language, employing more foreign workers, and investing more in social media ads. The percentages of the preferred source of ads were also obtained and were very useful in knowing which channel of advertisements to focus on more.
