The ability to use various ad formats in one account was very helpful for our clients as they could choose which format worked best for them without having multiple accounts set up. It does take some initial setup time to get going but once you have all your settings configured it's easy enough to manage an account when needed by someone else within your agency or client organization to do so if necessary (i.e., during busy season). I would like to see more reports available via API that can be used programmatically instead of just being able to export data into Excel/CSV files. Currently only CSV exports are supported at this point; however, we recently were upgraded to Adobe Analytics Premium where native reporting capabilities exist now (also not yet included) - hope these options will become even easier soon! We primarily provide white label services to agencies looking to add display network advertising solutions.
