I used Wordtracker, Google Adwords, and the Overture suggestion tool to research my keywords. Right now, my plan is to create 50 pages, one for each of the 50 states, to describe my widgets. Keywords like "Alabama Widgets" seem to be a great starting place.
The problem lies herein. There are only so many ways to describe my widgets, and I don't want to be banned by the search engines for looking spammy or having duplicate looking pages. What's the best approach to take when planning my all-american angle?
