The ability for us as an agency (and thus our clients) can see how many impressions are actually shown by each publisher from any one of your campaigns - so we know exactly where that impression was 'lost'. This information helps me understand what I have done wrong when creating my account settings/profile etc., which makes it easier than ever before! We also really love being able solve this problem without resorting too much into third party services or APIs with such great customer service behind them!! Nothing currently but there should be some formality around reporting within accounts if you want something more detailed eithin monthly reports?
