In the last two decades, the importance of the employee-company relationship has done nothing but increase. This fact has encouraged the application of marketing in human resources management by creating the theoretical body of employer branding, whose main objectives are to attract talent to the company and to commit them. Several factors have been shown to be capable of contributing to brand commitment. This research explores the experience concept of employer branding and its impact on affective commitment. A three dimensional structure of employer branding is proposed, made up of sensory, emotional and intellectual experience analogous to the commercial brand experience. The results, obtained through a survey of employees from different sectors and job levels, demonstrate the positive impact of the three types of experience described on affective commitment. A positive experience of the employer brand is important so that the employee develops affective commitment towards it.
