I have multiple books on
kindle, and while I do build backlinks to a degree, I never see much of a
change in my
page rank in a search for the keyword I was optimizing for.
A note to international users, this guide is intended to work with all
Kindles and is available through Amazon's various international websites, but the links in the book direct to Amazon's main website for tips regarding things like the Manage Your Content and Devices
pages, so obviously you'd have to go to your own localized Amazon store to make those
changes instead.
