Amazon’s Author Central helps you share the most up-to-date information about yourself and your works with millions of readers. You can obtain timely sales data for free, including sales trends over time and where in the US your books are selling. But the best part is Amazon’s author-trained staff answer your questions and help solve your problems through email or daytime phone support.
Even as an indie author, Amazon lets you create an author biography page that attaches to your ebook’s sales page. You can add your biography, photos, blog, video, and tour events to your Author Page (your homepage on Amazon.com).
You can share your background, your blog’s RSS feed (so it grabs new posts), upcoming speaking or book-signing events, and even your latest tweets.
Your Author Central page appears on every book sales page on Amazon, so it cross-links other books you’ve published. If someone clicks over to your author page, they can even subscribe to you and get emails when you release new books.
