Not to be too brash, but sometimes you've gotta call things as they are. I've reiterated time and time again, that the internet is becoming a place full of user-generated-content. The majority of the time, that's amateur content. Not that it lacks credibility, but it's a free-for-all with no journalistic ethics to regulate statements, or reviews for that matter.
Take for instance this article from SFGate.com about how a business owner got nearly driven out of business because of what reviewers were saying on a directory site. That directory site's response? Pay us - and we'll let you have the first comment section to yourself (above of all the negative reviews that people will still see).
Bottom line is this: you as business owner need to know what's being said on the web so you can proactively take steps to change your business method. We're the only place, that for FREE, shows you all the sites that allow reviews and show you how your business is listed AND include links back to those sites.
All I gotta say is, I pity the fool who ain't managing their online reputation.
