I have been meaning to write a series about how to properly use WordTracker, and why you even need a subscription keyword research service. But before I get to that, and that could take a while, you may want to take advantage of the promotion that WordTracker is running for December. They are giving 15% off on their subscriptions and they also are offering 9 mini-courses on keyword research which could be helpful if you need some SEO keyword research drills. The final price on one year of WordTracker will be $255, down from $299.
