Only read pages count for Amazon
Amazon will pay self-published authors based on how many pages have been actually read
A new Amazon publishing experiment is starting next Wednesday: authors who self-publish through Amazon's KDP Select Program will be paid based on how many pages have been read in their books, rather than the number of books downloaded.
Self-published authors will be paid for each page that remains on the screen long enough to be read, the first time a customer reads the book. Amazon says the change was made in response to authors who "asked us to better align payout with the length of books and how much customers read."
If a reader abandons a book half of the way in, the author gets only half of the money they would have earned if the reader stuck to the end. So much for the old publishing saying: "It doesn't matter how many people read your book, only how many buy it."
Amazon also developed for this the "Kindle Edition Normalized Page Count" (KENPC), using line spacing, font size and type, and line height to evaluate the number of pages in a book based on a standardized format. For instance, a smartphone may show 300 pages for a book, where a larger screen may display say 150 pages for the same book. Authors would be credited towards the KENPC count in both cases, that could add up to something in between.
