Social networks are most often described as a form of platform through which to communicate with other people. Social networks are also considered as a channel of communication without which it is impossible today to function both for natural people and for those with whom they are an unavoidable part of business. If a company wants to establish a relationship with customers, ie consumers, business partners, etc., it must have a strong connection with them and this can be achieved through social networks that are increasingly represented in the way of advertising. Many ask why social networks? The answer is simple. If the target group when advertising the product is a younger audience (eg 18-35 years). Then the advertising will take place through social networks because these are the platforms on which they spend their free time while some of them work and earn through them. Advertising is today the main component in product promotion, it is more and more represented and it could be said that it has reached its peak when we talk about product promotion. An influencer is a person or group of people who influences their audience. They have a certain number of followers on social networks, they are interesting to people and they use it in the best possible way. Most of them do just that, promote products and ensure their existence.
