The Book Deal, The Inside View of Publishing performs an in-depth analysis of this topic with some very helpful hints. Just as important, the comment string gives you additional insight as to what others are doing and how blog reviewers perceived the article.
There is no question that book review bloggers play an important role in the promotion of self published and traditionally published authors!
To give you an idea, in the coming months the following sites have either completed a review or agreed to review THE CARD:
Kristi's Book Nook
Two Kids and Tired Book Reviews
Bloggin about Books
Welcome to My Life
Two ends of the Pen
The Book Tree
A Soul Unsung
Stimulated Outlook Book Reviews
That is all that is lined up right now, with more coming online everyday. One of the advantages of blog reviewers is that most will post their reviews on their own blog, Amazon, Goodreads and just about any other place you request (Barnes and Noble, etc.)
It is a win-win for everyone involved.
