I like that we can quickly setup campaigns to target specific audiences/communities (e.g., Facebook ads) for each of our clients' accounts with one click - no need to manually create audience lists or go through various steps in order to have them show up in their account dashboard! It would be nice if they had some sort of reporting feature so you could see what is performing best compared to others across channels within your network as well as how it has performed over time vs other networks too! Also, there are times when we want something more detailed than just an ad group; this makes creating custom audiences very difficult because all targeting options require additional fields which means having these extra fields will make any campaign much longer due to the amount of data entry required.
This allows us to easily track performance throughout different markets and compare results between multiple marketing teams who work together.
