Our clients value our experience and our ability to make social marketing manageable and understandable to them.  It seems, however, like there's never enough demonstrable ROI to satisfy them, though their feedback is mostly positive on how much value they feel they receive from our services.  Clients feel confused about how to evaluate social media marketing results and they want success quickly, which is contrary to the reality of most marketing campaigns.  And they are extremely cautious about spending a portion of their marketing budget on what they see as an unproven strategy.  We would like them to give us enough of a runway on social marketing campaigns so that we have a shot at turning in the results we know we can get with more time than most are willing to give.
