Advancement of Internet and digitalisation of information has led to increase of data breach incidences in social networking sites (SNS) particularly Facebook, thus affecting its market value and reputation. The intriguing question is whether and how does data breach affects consumers’ behaviour towards Facebook advertising? The privacy literature provides inadequate account on this question. In order to fill the gap, the current paper analyses privacy in Facebook and investigates the consequences of perceived data breach (PDB) on consumers’ behaviour towards Facebook advertising. A systematic review of privacy literature was undertaken to answer the research question. This paper reveals that protection of consumers’ privacy in Facebook is in deficit, and it further hypothesises that PDB influences consumers’ behaviour negatively by discouraging both acceptance and engagement with ads. Moreover, PDB influences ad avoidance positively. Likewise, it influences consumers’ psychology by increasing privacy concerns and emotional violation and reducing trust concurrently. The findings of this study are not confirmatory; thus, a scope for further empirical research to test the developed model and inclusion of other mediating and moderating constructs is provided. Practically, this paper recommends tough personal data protection regulations and privacy policy that prohibit Facebook and other SNS from online tracking of consumers. Also, Facebook should build trust and revise privacy settings to enable consumers to opt in or out of receiving ads. Finally, this paper’s theoretical contribution is the model which proposes that perceived data breach affects consumers’ behaviour towards Facebook advertising both directly and indirectly through psychological mediating variables.
