This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.

Thank you so much for this great article, it was very helpful, you definitely have a lot of information here. I own a business, so I work quite a bit, but I really need something else to help me sustain, especially though the winter months because it’s mainly a seasonal business. I’m curious, when you first started, how did you find something that worked for you? I know it will take a lot of hard work, and that’s fine with me, but I get discouraged signing up for a lot of these sites and only making 10 cents on the 4 or 5 surveys or videos, or whatever they have to offer, then there’s nothing left. I’ll spend an hour getting signed up for these sites, then it only nets a dollar or something and it will say I have to wait for new work. And I know it takes time to build up, but what can I do or where can I go to see some real traction online? I’m working on building an O Desk profile too.

Build your audience on a course community: If you’re just getting started building an audience for yourself and want to leverage communities already actively looking for content you can choose to host and sell your online course on a site like Skillshare or Udemy.

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.
