Aside from creating products and selling them on the Clickbank marketplace, you could create Kindle books and list them on Amazon.
One advantage to this is the fact that once your book is done, customers browsing Amazon will find it (providing you targeted your keywords appropriately), and purchase it right from there.
Amazon already has the traffic, the trust.. and they make buying easy.
I know a few people that are publishing on Amazon (and createspace), and they’re doing well with it. The income is consistent (once you get rolling) and it tends to increase over time as the positive reviews start coming in.
You’re probably thinking that writing books is WAY too much work, right? Well, you don’t really have too. The guys I know who do it are just outsourcing the product creation, and I’m always surprised at how little they spend to get someone else to write their books.
There’s a course that teaches a formula for this whole process called Kindle Money Mastery. Click here to watch a video that explains it.
