HowSociable helps you learn more about your brand's visibility on the social web. You can check your own stats for free and they offer a FREE trial. You may purchase the pro edition for $19/mo. with added features. You can record your visibility history and save it forever. It tracks through 20 social channels like Twitter, Facebook, YouTube, Google, etc. This service has been around since 2008 and has made improvements along the way. They offer a service where they email you reports monthly for FREE. So you can forget about it until it arrives in your email. (I have not done the pro version and get the emails - nice feature.)
