There are several tools you can use to monitor social media sites and what people are saying about your brand. One great tool is Social Mention. Social Mention, is a social media search engine that searches user-generated content such as Twitter, Facebook and Blogs.

You can sign-up for free and set up keywords or phrases that you would like to have monitored. Anytime those keywords are mentioned you will receive an email notification. You can also set up the frequency that you receive these notifications.
