A system and method are presented to activate a real estate searching app on a mobile device through the input of an activation code. The code is associated in a database at a remote server with a first real estate professional. When the code is entered, the mobile device sends to the server the code and the current geographic location of the device. The server verifies the code to allow access to the app. The server uses the database to identify the first real estate professionals and also other professionals associated in the database with the first real estate professional. All of the identified professionals are then marketed on the mobile app. Furthermore, the server compares the time and location of the code entry with marketing events by the first professional in order to analyze the effectiveness of these marketing events.
