Abstract : This paper studied the web communication strategies of three Tunisian companies namely "Art de Tunisie", "Golden Yasmin" and "SIMAP". The study was based on the analysis of interviews with the leaders of these companies. Il also tried to analyse the companies' activities as well as the the different communication media they used. To this end, an analytical framework was developed and applied based on the marketing approach of companies' communication strategies. Results show that these three companies use different strategies. "Art de Tunisie" adopts a strategy that is closest to "purely online" communication. "Golden Yasmin", however, adopts a "mixed" communication strategy while "SIMAP" uses a "mixed" strategy closest to "off line" communication.
