SEO Tools & Training
Market Samurai is the best tool I have found so far for everything relating to keyword research and SEO. It allows me to create keyword lists, research markets, and more importantly spy on my competition. It also helps me pull material together for writing my keyword related blog posts.
They have a FREE trial version that I recommend you take advantage of. If nothing else sneak in and watch all of their videos.
I will post more of my tools over time. Hope this helps.
