Any Good Keyword Extracting Tools?

[XXXXXXXX]

I need to find a bunch of keywords on a subject. I have gone to the google keyword external tool and found a bunch. I was wondering if there is software that can make this easier for free. So for example....lets say my main keyword in the google keyword tool is for example (WebsiteTraffic) ...now a ton of results come up. Now I want to take each one of those results and drill down one more level. So what I mean is I put in Website Traffic and bunch of stuff comes up so for example SEO or Get Website Traffic or Increase Traffic comes up...now I want to go to each one of those keywords and put it in the tool and drill down one more level for more keywords.

Is there some free software out there that does that? I know Market Samurai does but I was looking for a free options.

Any Warrior with any idea on this?

Thanks X

I don't know about any free option. In fact, I don't think you can get something like that for free.

But if you're willing to pay, there's a software called Scrapebox. It's really powerful, able to drill down and harvest keywords using Google keyword tool and search suggestion, or using the Google Wonder Wheel.

But it borders on blackhat, so some people might find it distasteful.

Try Google Suggestor.
