As an author, it's not only important to have your own blog. To really sell your book, you need to cross pollinate with other bloggers, bloggers who'll help you reach tried and true fans of your genre and style and bloggers who'll help you enter new markets of potential fans.

What's your outreach like now? What are you doing to help bloggers entertain and inform their fans? Have you emailed a blogger asking what types of stories they look to cover? Doing so let's you in on how to how help them with topics? Do you actively follow blogs and regularly leave comments? When you do this you demonstrate loyalty and trust. Being helpful, loyal and trustworthy: these are elements that naturally inspire relationships. Relationship building is what blogger outreach is about. As an author, if you support a blog with your good ideas and regular participation and duplicate this with other bloggers, you're bound to land reciprocity. You're bound to have someone share your latest title with his readers. Some of these readers will buy your book. You get all this for the low cost and being friendly, helpful and loyal.
