I would like to give you guys a great place where I learned all my keyword research. It's called The Keyword Academy, found at TheKeywordAcademy.com. It taught me exactly how to build niche sites and how to promote them, and so far things are going well. I now have 18 niche sites, and my best one is ranking #3 for the targeted keyphrase. I am not making much money yet, but in a few months I definitely will. This is a long term investment of both time and money, but if you believe in yourself and your sites, you will be successful.
