This is very good. This is bar none one of the best tools I have ever seen for the proper data visualizations and representations that exist in a keyword list.
That wordtree report visualization is absolutely brilliant, you guys rock!
This is very exciting! I agree that keyword categorization is definitely the right way to think. I'm testing out the demo version as we speak. Keep up the great work.
Looks amazing, I will implement it and start working for my own website. I think that for search marketing / SEO companies this will be a killer tool. It can add a huge value!
