Booking a trip following the discovery of a destination thanks to an influencer's post is now a common act. With the rise of social networks, but also their multiplication, the number of influencers has only increased in recent years. New actors who know perfectly how to address the younger generations in order to influence their choices. A power of persuasion that has not gone unnoticed by tourism professionals, both private and public, who are increasingly using influence marketing in their promotional activities.
