It gets better. Amazon allows you to post a RSS feed from your website onto the Author Page's Author Updates section.
So for example
If you look at my Author page, it has my RSS feed with links pointing to articles I have written. These links are high quality DA links that will probably not get stepped on by Google.
Each one of these links is currently a follow link.
If I can boost the Page Authority through a backlink campaign to the Author page, I can have a serious high domain/Page Authority backlink to each of my articles.
Amazon right now according to Moz has a DA of 98.
If you have a Wordpress website, Amazon makes it easy to add your RSS feed to the Author page.
For Wordpress Amazon just need the URL/Feed
