Abstract

This research aims to identify the factors that precede consumer satisfaction and how this influences brand loyalty in the Portuguese consumer products and services market. The methodology used was based on a literature review on relationship marketing, brands, satisfaction and loyalty. Subsequently, an online survey was carried out, distributed via social networks. A total of 513 valid responses were obtained. The data was processed using SPSS, version 27.0. The results show that there are three factors that precede satisfaction and that two of them influence it positively, while one factor influences satisfaction negatively. It was also found that there is a very strong and positive relationship between satisfaction and loyalty, as in other studies. The results of this research could be useful for the academic community, particularly in marketing education, as well as for marketing professionals interested in studying loyalty factors.
