The central problem aims to determine the extent of the influence of the determinants of the e-wom on the purchase intention and how this correlation is modulated by the perception of the customer. To answer this question by taking the Apple brand as a case study. We conducted a quantitative study including an online questionnaire. Thanks to the latter, we collected 100 responses from Algerian consumers who were processed via SPSS and Smart PLS software for data analysis. The data significantly indicate that the e-WOM plays a crucial role in the purchase decision, thus reorganizing the information environment.
