As well as selling your eBooks, Amazon can also create paperback copies of your book. CreateSpace, an Amazon-owned company, will help you self-publish your book. A relatively straightforward process, you must upload your work to CreateSpace and submit it for review. Your book will then be displayed on Amazon, and printed on demand and shipped by CreateSpace when purchased. And you can collect up to 70% royalties for each book sold.
Drop shipping is another great ‘hands-off’ way to sell products. Firstly you will need to find businesses that sell products in your niche that offer a drop shipping service. Then you will need to create a website promoting and selling the products. When you make a sale, you take the payment on your site and then the manufacturer ships the goods to the buyer. The profit comes from charging a higher rate than the manufacturer, and if you are selling a high number of products this can quickly add up to a healthy revenue.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
