Now let me state this before anyone does it. Anything you use verbadium...Quote where you got it. Plagiarism is no game, and as marketers who make money(or goals of making) online should take it seriously.
With that being said here is a great way to use this source. First, go to your local library. Do your keyword research to find a niche like...Lawn Maintenance. Now in the section where you find Lawn Maintenance look for a book on a sub-niche. Just for the sake of conversation try Annuals. Find your library check it out for FREE. You now have all the info for all the content you need on the subject. As long as you re-checkout your book or books as needed it didn't cost you a dime.
Am I wrong about this? What does everyone else think?
