I found this tool that will help you with keywords:-
Keyword Density Checker
All you have to do input your url and this will scan your website and displays certain keywords and then it display the density as a %, and it will show you how much that keyword (and ones related to it) receive hits per month, it's a cool thing and helps you to insert certain keywords into your website. Might help you more with SEO, and perhaps your website will recieve more hits
