Stacey Miller points out that SEO is a very important promotional tool for authors. In fact, it should rank right up there (no pun intended) with excerpts, bookstore signings, reviews, etc. If someone has heard you’re an author of a book and they Google your name, what are they going to find? What are the key words and phrases people are likely to type into Google if they’re looking for topics covered in your book? If the book information isn’t towards the top of that first screen of Google results you need SEO help.
There are loads of free SEO resources available online, as a quick Googling illustrates. Or, head over to your favorite online bookstore and buy one of the many good SEO titles currently available. (I’m still working through our own Search Engine Optimization: An Hour a Day and will post a review when I’m finished.)
