Our first CTA is usually for another purchase: either the next book or a bundle of multiple books. After that we’ll have a call to join our e-mail list in order to get upcoming books free or at a discount. We often follow with a third CTA that contains either a list of our other books or (preferably) a link to a web page with that list (seeing as we can update the webpage easily but don’t want to update all of our books’ CTAs). Somewhere in there we usually try adding a request for the reader to leave a review for the book they’ve just read.
