This approach definitely works. I teach Internet Marketing and my classes cost between $895 and $1,895 for two to five days of instruction.
Last July, I held my first free 1 1/2 hour seminar and my paid classes are now selling out! Even if a person doesn't register for the paid class, I have given them very relevant and valuable information that they may pass along and help build buzz.
My marketing costs have also gone way down using this approach.
Thanks for sharing this great article!
