Amazon makes it easy for authors to get additional exposure with their free Author Central service. This allows authors to create a custom profile that includes your bio and blog feed. You can also use this to modify the description for your book on Amazon.
Some new features have been added recently so if you haven’t updated your Author Central account lately, now is the time! You can now add your Twitter feed to your profile. You can also write a note to readers directly on your book’s sales page. You can also integrate all kinds of details about your book with Shelfari.
Make sure to take advantage of all the features in Author Central!
