Reading my books through Kindle Unlimited still supports me, in case you came here worried it didn’t. There are two ways to explain how it works. The short version is that I am paid per page read. The long version is that I am not paid anything until you read past 10% of the book. After that point, I am paid for every page you have read and then every page you read from then on. What also happens after passing 10% is the ranking of my book increases as if it was purchased normally. This helps give it more exposure on Amazon, just as a purchase would for any book. The amount that Amazon pays per page read fluctuates each month, but as an author I am happy with the system. Not every author is as supportive, though, because to have your book in the Kindle Unlimited system means you have to sell exclusively on Amazon.
