We use HootSuite Free to initially examine the cross-social media postings and activities of a client. It is too bad of a UI to use as an enterprise edition and too limited in analytics to use as a true client solution but you get what you pay for and it's a very low cost ($0, no setup fee) way to start getting a grip on a client's state of affairs in social media. Its popularity makes it a good initial sell for research purposes before we move to a solution which both has a better UI and has a more client-specific features (namely in reporting and analytics where HootSuite suffers in, perhaps as it's meant for management). HootSuite Free is also useful for increasing activity on clients' social channels at the lowest price just to get the client to feel confident about their social media activity rate before moving onto a more fully featured service. Pro ($14.99/mo) is required for any useful feature so Free is obviously only intended to get users to pay. We use it only on new clients who have naive or no social media experience. We ultimately usher them to mostly SproutSocial (most clients, small to mid) or Percolate (big, corporate clients).
