A couple of weeks ago I mentioned two tools to assist you in monitoring your brand on the web (and how to legally spy on your competitors).
While both the tools I mentioned (Google Alerts and Twitter Alerts) are great tools, these next two tools are far superior and offer a much more comprehensive solution.
Cruvee. Specifically focused on the wine industry, this is a great product that monitors your brand in wine blogs, twitter, forums, friend feeds, etc. I've seen the demos, and this product is pretty cool. Monitor and analyze your brand, what is being said about you, how it compares to your competitors, etc.
Techrigy. This product also allows you to monitor your reputation and brand online. (It's been called Google Alerts on Steroids). I've set up Vin|65 with an account, and the reports look great, although I'm still just figuring it out.
