Virtual social media has been changing the way consumers interact and communicate to each other. The online environment has allowed people to access a great amount of data in a quick-and-cheap way. In face of that, digital opinion leaders emerge as important sources of information, providing expert opinions about products and services. Since there is a wide amount of consumption-related messages available, it could be interesting to understand how this type of message can interfere with consumers shopping intentions. On this study, it is hypothised that after having access to persuasive messages published by digital opinion leaders, one tends to accept the information and change its attitude towards buying what was recommended. These two factors, then, impactate consumer s shopping intentions. Online surveys were conducted with 204 followers of the Brazilian account Comprei e Aprovei on Instagram, an online social media. The data was analyzed through structural equation modeling in order to test whether or not the proposed model and its hypotheses could be validated. Based on the collected data, it was possible to verify that a digital opinion leader that is capable of creating persuasive messages can change the attitude of their followers and lead them to accept the given information, and through that, increase their intention to buy the evaluated products or services. All this emphasize the relevance of these opinion leaders in Marketing-strategy contexts.
