Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money. But it is a resource you can use in your spare time to generate a small income online.
Completing paid surveys is a much easier process. If you know how to give your earnest opinion about a topic, you have all the skills necessary to get started right now. All you're asked to do is share your genuine thoughts and feelings about products, events, marketing campaigns and more. That could mean picking between multiple-choice options or answering a more open-ended question. Either way, the concept is simple and easy to pick up and run with.
Whether you have a website or are still dreaming up ideas for a blog, you can also look into affiliate marketing. With affiliate marketing, you partner with brands and businesses within the content of your website. If you mention a product or service, you link to that produce or service using a unique affiliate code you received when you signed up for that particular affiliate program. From there, you’ll make money any time someone buys a product or service through your link.
