▪Social context: This category reflects whether the user’s location is associated to a specific social event, which can be used to tailor advertisements to the user. Moreover, also knowing whether consumers are by themselves or part of a group provides possibilities for adapting advertisements (e.g., not advertising a deal for a one-person meal when a user is with several people) (Sa et al. 2013).▪ Need: User needs may be explicitly expressed such as looking for a specific book that a user requires for study. An example for a user’s current need may, though, also be implicit such as ‘feeling hungry’ is actually a symptom for a user’s need for food.▪ Activity: An activity that a consumer is currently engaged in, be it sports, entertainment, or work, may be a basis for the kind of advertisement that is relevant in this moment (Simoes et al. 2009).
