Social networks represents a revolutionary change in the way people communicate, share information, and connect on a global scale. They have become an indispensable part of modern life and thus play a crucial role in shaping many industries, including tourism. Social networks are increasingly being used for travel purposes because tourists can more easily explore destinations, plan trips, and share their experiences. Platforms like Facebook, Instagram, TikTok, and YouTube allow users to share photos, videos, and reviews, which play a key role in the decision-making process for choosing a travel destination. On the other hand, tourist destinations and service providers have recognized the importance of having a presence on social networks and use these platforms for promotion and communication with potential visitors. Influencers play a significant role in promoting travel destinations since they reach a wider audience and can attract a larger number of visitors. However, the introduction of social networks into tourism also includes challenges such as bad reviews and negative comments, which can greatly impact the choice of a travel destination. The aim of this paper is to explore how social networks affects tourism.
