The Jacob Sartorius “Over U” Presave Contest (http://zip2.it/overu) is a great example of our new family of viral presave contest applications (for Spotify, Apple and Deezer) that encourages users to both presave and aggressively share the campaign with their friends. Unlike regular sweepstakes, this type of activation rewards users based on the number of people they invite to participate. In this particular campaign, 75% of those participating were referred by a friend, amplifying presave activity by four times (4x), You can check out the campaign here. This particular campaign has support for both Spotify and Apple presave options. You can also check out other examples of this new category of activation here: http://news.metablocks.com/lists/566-4115899158
Once a user completes the presave activation, they are given a unique link they can share with friends on social media or via email. When any of their friends use the link, the user who invited them gets a point and the system keeps track of which users have the most points.
All of our activations are optimized and test for a broad range of popular mobile devices.
