Sorry if it's been asked, but I did search first I like the keywords suggestions tool and find it very useful. Would there be a way to calculate the KEI at the same time?
I found a good tutorial on calculating the KEI of a keyword. You can find it at http://www.seotutors.net/tutorial/choosing-correct-keywords-site Hope it helps. Haven't found any tool which automatically gives the KEI, except if you sign up with a Wordtracker account.
