Checkout these Social Media monitoring tools.

Google Alerts

These are an absolute basic minimum, that everyone should be doing. Set up a Google account and set up some Alerts, for you, your brand, your company or any keywords you want to track. As soon as it is mentioned on the web Google will tell you about it with an email to your inbox!

Tweetdeck

If you are a Twitter user, then this is an absolute must. The ability to track real-time what is being said about whatever you choose, is very powerful indeed. It is easy to use and set up, and it will even play you a sound when someone has mentioned you!

This is just superb, and also fun to use. Put in a simple search, and it will show the results in a page full of widget type boxes across a whole range of platforms - video, blogs, networks, search networks etc. Love this!!
