摘要：This article intends to generally understand the possible reasons why the users engage within this social network analyzing selected publications of three Facebook pages and more specically, to observe the ethos, aphorize and the support roles for that engagement. In this sense, this paper considers that membership on Facebook pages are the result of the image coparticipants builds and this image is even built before the discourse of the participants itself has taken place. The corpus consists on three pro les selected from the Internet through the Google domain search functionality and the theoretical frame followed was the French discourse analysis, particularly Dominique Maingueneau.The research results revealed that the pre-discourse ethos and aphorizing adopt an important role for the users’ commitment in the analyzed pages as well as the support. Nonetheless, as the support is the same for the studied pages it cannot be considered a discursive element that causes different adhesions related to them. Regarding the textual genre, it does not appear as a discursive element that contributes signicantly to the adhesions.
