BTW I want to share these two tips with everyone, that helped me research more about my “ideal reader / customer”.
* Amazon.com Reviews: Read customer reviews of products that are similar to your products. The reviews contain really good insights on their hopes, dreams, expectations & problem areas. In my case, my first book was on Amazon and the reviews helped me refine the purpose of by blog.
* Facebook Graph Search. If your business has a facebook page, it’ll allow you to do searches like “Books liked by people who like [Your Page Name]”. It will show you an actual list of books your facebook fans read. This post has some more details: http://jensmithsocial.com/use-graph-search-find-ideal-audience-inside-facebook/
