My mailbox is generous of advice on how to market my book— often questionable. But Shelli Hite’s book, Marketing Your Book On Amazon, deals only with one subject—Amazon.
The author covers every step on The Amazon sales page. She includes everything from categories to getting reviews. I intend to go chapter by chapter and follow her suggestions.
The only issue I found was a link that no longer existed, but blogs disappear on the internet daily. I won't count off for that. Well worth reading.
