Here’s what you can do:
- Set up Google Alert by keywords to get emails anytime someone talks about you
- Use SocialMention to track and measure conversations about you and your competitors on major sites and social networks. You can also add a widget on your website.

- Monitor the blogosphere through Technorati.
