Report Groups for Adobe Target's Automated Personalization

I have long been a big fan of Automated Personalization (AP) in Adobe Target. One of the critical features to extract as much value from it as possible is Report Groups for offers used in AP.
Report Groups allow you to folder or bucket similar offer themes. One client of mine recently took my advice to do this exercise and, since doing so, has realized a 28% lift with the targeted group vs. control by raising the conversion lift to 9% from 7%
This video shows you this concept in action.
