Are there any software that gives you good keywords to use them for your website ??
Zourkas, I agree with Fredbaughix and marcemusza have to say about Market Samurai. That its a great tool, Has a learning curve but well worth it. Its my favorite one compared against some others I have tried. (Traffic Travis and wordtracker) Wordtracker is a more premium product with higher fees.
One site I might suggest is Seobook they have some useful free tools that may help you out.
