Looks great Linda!
I'm wondering if the keywords you are tracking and researching are not being used for their own research and website developments?
For instance you have found an interesting niche to target and see an "acceptable" amount of actual competing pages and then using these tools may tip of the supplier of these tools and you gain a powerful competitor you would not have had if you did not use these tools.
It just makes you think with all these tools coming out which is great of course but how discreet are these tools or are they being used to mine data that they can exploit for their own?
