In the ongoing debate about whether or not to list your indie book exclusively with one retailer, there are a few things that authors have to consider. Chief among the concerns usually falls back on sales: where are your books selling? If readers only come to your book via Amazon, for example, and you literally post zero sales on other platforms, it would make sense to then go ahead and take advantage of Amazon’s KDP Select.
However, a new issue with Select, namely the books’ inclusion in the Kindle Unlimited reading platform, means that authors are currently paid out at around 0.04 cents per page for KU readers, an amount that has been steadily dropping all year. That’s not four cents, by the way, but rather point-of-four cents. That means a 200-page novel will net the author eight cents if a reader finishes the whole thing; even further, an author will only get paid the first time the reader enjoys the book. A number of authors have decided to pull their books from KDP Select for the sheer gamble of hoping that someone would buy the book rather than read it at that rate.
