People no longer head for the nearest bookstore, instead they head for their keyboards when they want to find a good book. That is why it is more important than ever to have a web presence that invites readers, gains a following and sells your book.
A media kit, blog, Facebook page and Twitter account are a necessity for authors, particularly independent authors who have to make their own noise about their products. It is equally important to have a polished and professional presence on the Internet. Your competitors have set the bar high in this regard and to offer anything less is going to result in lost sales.
It is not expensive or difficult to maintain, it is just essential to selling your book online.
