Been slowly going through Dan's excellent SEO book and was wondering? He suggests 'Keyword Discovery' and 'Wordtracker' to start off your research but I was thinking (again) is it possible to use my Market Samurai and would the sequence be the same? Or are they different tools altogether? I have used the Market Samurai software doing the 30day challenge but have only used it sparingly since then, so I do have minimal experience.
Hopefully someone can explain how and why?

Going through SEO Fast Start slow and steady since the absorption rate in my brain is a lot slower than it use to be. Must be age I guess and a bit too much partying in my younger days

Thanks everybody!
