I have been searching for a keyword generator, or a software that would help me get better results with AdWords. I found several interesting tools among them is WordTracker, this is the best I have tried so far. But I think it´s a little expensive. So I am not using it just yet (maybe later on).
Today I found a new software called The Permutator and it´s supposed to be the ultimate keyword phrase generator, and it even has a free trial. I haven´t downloaded it just yet, but I will try it soon.
Take a look at The Permutator at Boxer Software.
