With the vigorous development of new media, there are more new choices for marketing methods. However, we haven't found the research about the suitability between different kinds of products and the marketing methods. Therefore, we decided to use conventional media (newspapers, TV, Out-of-home advertising, radio, and magazines) and mainstream media (online media) as the main method to investigate the influence of marketing methods on purchase intentions. By collecting questionnaires and analysing them with SPSS, we can understand the difference in the reception rate of consumers' information and the related impact on purchase intention under different marketing methods. It is hoped that through this research, it can provide a reference for the selection of marketing methods for related products, and further help companies to have a deeper understanding of consumers during marketing.
