I use Keywordspy a lot and it helped me an amazing amount, as in my SERPS went from nothing to the top of the first page. But with this... My RPM quadrupled as I was able to hone my copy to a point where even great SERPS helped insanely, but I was seeing the *right* kind of traffic as well. I wholeheartedly recommend this to anyone who has a website and can follow simple directions. I'm extremely happy with my purchase and am recommending this to all my friends, both business owners and SEO experts. You can never have enough software variables to perfect the art, and this is a big one!
