Creating and selling courses on your blog can be a successful way to make money online. The course itself should be relevant to your blog, and based on a topic that will benefit your audience. Although it may take time to create the course in the first instance, once completed, you can then repeatedly make money from the course each time you sell it.
This is the favorite one of the legal ways to earn money online or on the internet for many Internet marketers. The reason is that you can be very profitable if done correctly. You you have to sell the products of other people and you they pay a Commission for it. The products that are sold are ebooks and digital products.

I also participate in online surveys through the following websites, that work in the US and internationally (I use them all and I'm based in Brazil, for example) - Opinion Bureau, Myiyo, and Green Panthera. All of them have a variety of surveys and pay well. All you need to make money is to have 20 min or so to answer a few questions every day/week and have an active Paypal account so you can cash out.
Videos are everywhere on the Internet and some work at home websites will give you the opportunity to get paid for watching them. Video creators get paid for every hit their video receives online. Those who are new to the business will often try to maximize the views by sharing small profits with those who are registered to watch the videos for pay. You will earn a few cents per video watched and can kick back on the couch while doing it.
