With the development and growth of internet technology, marketing practices have been redefined worldwide. The Internet has changed the way consumers encounter brands, making a direct impact on the transformation of the economy and marketing. Traditional marketing strategies have become insufficient and unsustainable for many companies. Digital marketing today has become one of the key areas of focus for businesses around the world. It started as a way of communication and evolved, not only into another source of additional income, but most importantly, into developing and maintaining long-term relationships with different market groups. This paper deals with the topic entitled "Analysis of the application of digital marketing with the aim of increasing sales on the example of the selected company." The idea and motivation for dealing with this topic comes from the author's business activities, and knowledge of the importance of digital marketing and its role in creating and maintaining a brand, as well as in creating relationships with customers, which has a strong impact on product sales. The primary research was conducted using a survey questionnaire, and the results of the research showed that the Heineken brand has room for improvements in the application of digital marketing that can boost sales in the Croatian market.
