A social networking system enables targeted advertising to its users on mobile devices, either directly in third-party applications or via an ad exchange. An application on the mobile device associated with the social networking system stores user identifying information in a shared memory location on the user's mobile device. To deliver a targeted ad to the user on the mobile device, an application executed by the mobile device retrieves the user identifying information, which is transmitted to an ad server associated with the social networking system or to the social networking system. Based on the user's profile in the social networking system, an advertisement is selected for the user (e.g., using targeting criteria and an auction model) and sent to an ad exchange or to the application on the mobile device for presentation to the user on the mobile device. |
