<p>An online system, such as a social networking system, enables targeted advertising to its users across platforms, such as mobile applications, desktop browsers, and mobile browsers. The online system stores interactions with advertisements or other content from multiple platforms with a user identifier. When an advertisement request is received including the user identifier, the stored interactions associated with the user identifier are retrieved, allowing an advertisement to be selected based on user interactions through various platforms. This improves advertisement delivery, such as advertisement retargeting, and conversion tracking.</p> |
