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. 
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. These are easy, cost-effective ways to build an audience and test your niche to see if there’s demand for it.

Nice sharing and totally informative for those who want to earn online. I have heard a lot about watching ads and complete survey, and I want to know that do they really pay? I read that lots of fraud sites are there which offer such service and takes money to signup and then they are not paying to users. Can you please share trustable sites if you have some?

Busy professionals outsource their laundry more often than you would think. If you live in a dorm or apartment building, you could offer to start a laundry service for all your friends and neighbors. Instead of them having to make their own trip to the laundromat, you could combine their trip with yours, and charge them a small fee for it. Considering you do laundry each week, this could be a great recurring revenue stream.
Money can be earned and spent, saved and pilfered, invested and wasted. Not time. That's why time is far more valuable than money. The point? When you lack the luxury of time, making money online (or offline) can seem like an impossible task. How are you supposed to do that when you're working at a life-sucking nine-to-five job? While the stability of full-time employment might allow most to sleep well at night, it doesn't empower your creative juices to search for new income-producing strategies.
Set up the site. Choose a website building platform, such as WordPress, Joomla or Drupal. Next, choose a domain name and web hosting for your site. The domain name is your web address. Web hosting is a service that connects your site to the internet. Once you have your domain name and web hosting, go to the control panel of your hosting account and install your website platform. Design your website by choosing and installing a theme.[9]
Of course, blogging isn’t for everyone. While you don’t need any prior internet experience (we had never even heard of WordPress before starting our blog), if you don’t enjoy writing about topics you’re passionate about, taking photos and social media, then this job obviously isn’t for you. In that case, we’ve included many other online jobs in this post to help you earn money remotely.
The first follows the startup path we outlined above: You have a disruptive idea for an app or piece of software, you validate the idea with real customers, and then raise money to hire developers or a development studio to build, launch, and scale your software. If you’ve done everything right, your software will be accepted to the Apple and Google Stores and you’ll make money every time someone downloads it or pays for a premium feature.
Amazon will have you work on micro-projects that require some sort of human interaction. Tasks can include translating a paragraph into English (or another language), rating the search results for certain keywords, or reworking an article. The tasks are simple, and you will be paid a small amount to complete each. But if you do enough tasks quickly, you can make a respectable amount of money.
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.
Peer-to-peer lending is an interesting concept, because it allows individuals to secure relatively large loans without getting a bank involved.  On its face, it sounds like a risky proposition, but these P2P lending sites generally have good measures in place to mitigate your risk (not to mention, you’re compensated for this risk by earning very high interest rates).  In addition, you can usually invest in someone else’s loan for a small amount (e.g. $25), which reduces the risk you take for any given loan.

Great list! I have another to consider that I personally have 35+ years experience providing. Clean up litter outside commercial properties on foot using inexpensive hand tools. It’s almost as easy to do as going for a walk! I started doing this as a side gig in 1981 and soon grew it into a profitable full-time business. I share my experience in my book, Cleanlots.
Holly told me she started writing content in 2011. At the time, she still worked a full-time job but created content online part-time to supplement her income. Over time, she was able to double and triple her rates until she could quit her full-time job to write. These days, she makes bank as a freelance writer and teaches others to do the same via her online course, Earn More Writing.
