This master thesis departs from the argument that a higher level of consumer trust results in a higher level of return on investment. The purpose of this thesis was to test which social media aspects increase consumer trust. As a respond to the purpose and research question a deductive approach was applied to this research. There were two marketing theories used in order to create five hypothesises that were all connected to increasing consumer trust through social media. The hypothesises were tested by sending a survey with the use of an e-mail database from the marketing company Creative Circle and School Supply. 236 respondents were the result of sending the survey, on which the empirical results are based. The study revealed that the social media aspects communication, response rate, reviews, content quality and profile engagement are all positively related to trust. The outcome of the research shows that when social media aspects are used as the research suggests, the level of consumer trust through social media increases.
