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 the specific audience. Mobile in-app advertising is growing in popularity.
