Starting with version 3 SmartSocial now supports SubIDs. These can be used to better track commissions. While creating a SmartSocial shortlink you are now able to provide up to 30 charaters containing numbers, letters, minus and underscores. These characters then also show up in the commission report within the adgoal backend for every commission made via that link https://www.adgoal.de/publisher/transactions.html
