My Social Database Native Targeting was also implemented, which allowed to include the specific classical music audience.

GEO: Global





Amazing results were achieved in close cooperation and communication between Wise.Blue and Primaphonic teams. Campaigns were being optimised on a daily basis and tested towards various targets, such as Cost per Sign-up. The teams also continuously tested and compared new creatives and ad copies. Identifying what works best, the focus was shifted to those ad and target variations to achieve optimal results.



Moreover, Twitter became one of the leading and preferred acquisition channels. The cooperation paid off immensely, and after 15 months we achieved the
same number of installs as at the beginning, but with 2x less spend. We decreased the total costs per Sign-up by 81% and the total cost per Purchase by 65%.
