Those sites do not correctly evaluate an online business. It looks like they use traffic flow to calculate worth. If they are a traditional business and just have a website for online appeal than it can not correctly evaluate the business wouldn't you agree?
well dnscoop.com is much much better than the sites above. tells you nearly accurate. not crap like above sites..
The best site to check how much your site is worth go to dnscoop.com they will be the closest in value.
Yup...I have to agree. I wouldn't these too seriously. I wouldn't say accuracy is their strong point...
