The rapid growth of the social network has led to making availability in customer tastes and preferences. This data can be exploited to serve the customers better and offer them the advertisements they would be glad to see. To provide a relevant advertisement to consumers, one has to consider the location of the consumer as well. The consumers will highly contend if the offers shown to them are easily accessible in nearby areas. Advertisements have become today’s most direct marketing channel that provides information and discount offers about products to customers and allow marketers to reach a precise goal by creating campaigns. Making these Ads location-specific would not only render them more relevant but also personalized and targeted to a specific audience. Mobile in-app advertising is growing in popularity. While these ads have excellent user-tracking properties through mobile device GPS, they have raised concerns among privacy advocates. There is an ongoing debate on the value of different types of mobile targeting, the incentives of ad-networks to engage in behavioral targeting and share user-data with advertisers, and the role of regulation.
