Have you considered leveraging Amazon to drive traffic to your website? In Simple Marketing Pro in the Skill Building library the Websites and Online Strategies has a section on Amazon.  In addition, we have a task list for using Amazon effectively.   I have one more suggestion for using Amazon that is not in the documentation and that is the use of Guides.  No matter what your expertise you can create a guide within Amazon. Using a combination of your knowledge and including books or audios that you would recommend for others to increase their knowledge.   Here is an example of one Starting a New Business

To create your own go to Guide go to Your Account within Amazon at the bottom of the page you will see Personalization: Community: Public Profile: Under Contributions, you will see a tab for Guides.  Have fun creating something of real value to share with your fans.

Once you have created your own guide then of course share it with me, your social networks, include a link in your newsletter, etc. This is a great way to demonstrate your expertise.
