The paper deals with basic categories and concepts such as marketing and digital marketing from theoretical and then from applied point of view. Social networks have fast evolved into a tool that can be used not just for communication but also for improved company operations. When developing a digital marketing strategy, it is vital to include a plan for appearing on social media and distinguishing out from the competitors. The paper examined the use of marketing on social networks using the company "About you" as example. It is a fashion and technology company with the goal of standing out with a fresh, digital, and personalized web shop. It is exactly because of this that it is regarded as a must-see shopping destination across the world. ''About you'' communicates with its clients using email and advertisements on social media platforms such as Facebook, Instagram, Tik Tok, and YouTube. Young and middle-aged women and men are the key demographics covered. The company's campaigns aim to customize and suit the demands of many groups of individuals, as well as all lifestyles and trends that fluctuate from season to season. Their financial results demonstrate that clients are quite content with what the firm represents and delivers, and strong marketing through social networks undoubtedly contributed to this.
