In one embodiment, a server receives a first URL link from a first mobile device of a first user. In response to the first URL link, the server determines whether a first mobile application that is associated with the URL link has been installed at the first mobile device. If the first mobile application has not been installed at the first mobile device, interactive data of the first user with respect to the first URL link is collected and stored in an event database of the server. If the first mobile application has been installed at the first mobile device, first data that is associated with the first URL link is retrieved from the link database and a second URL link is generated, the second URL link including the first data embedded therein. The second URL link is transmitted to the first mobile device.
