In the era of the digital revolution, digitalization is a force that forces the hotel sector to mainly go through a change in the customer journey, given that the user searches for their destination, chooses, buys, then enjoys and shares their experience. This journey is completely revisited thanks to digital, because now, consumers are looking for offers and sharing their photos and videos via different digital channels, and often directly from their vacation. The aim of our research is to understand the concepts linked to digital marketing and the hotel sector and how digital marketing impacts the e-reputation of the hotel, and to answer our problem «How digital marketing in the hotel sector contributes to does it promote tourism in a Moroccan destination ?» we have chosen a quantitative study through a questionnaire which will be aimed at tourists interested in the use of digital tools in their daily life and who like to travel to the city EL JADIDA as the case of our Moroccan tourist destination. The results received from the SPPS software show that digital marketing strategies such as digital content have a positive impact on the tourist promotion of the city EL JADIDA.
