Yes, absolutely. By publishing a book on Amazon, you'll be able to use it to build an e-mail list of readers that you can then profit more from through affiliate marketing.
If you’re going to publish a book on Amazon, then you’d want to ensure that you use that book to build a relationship with your readers and create an e-mail list. With an e-mail list, one of the easiest and best ways to monetize it is through affiliate marketing by promoting relevant, quality products and services that you can earn a commission. This is how you can monetize the back-end of your business, and in many cases, make more money from affiliate marketing than you will from your book sales.
