I personally like this one for some spare cash. It does not take much to earn an extra $20 – $50 a week. Some claim that they are able to make a living by dedicating their time to different jobs at mTurk. You will have to go through a learning curve, but once you get comfortable, you will find plenty of good and interesting HITs (Human Intelligence Tasks) to work on.
Mechanical Turk is Amazon's take on micro-jobs. These are small miniscule-jobs that you can do for other people, which they call HITs, or Human Intelligence Tasks. These are super simple tasks that anyone can do. Some examples are listing off some URLs with certain kinds of images for one cent, or recording a few phrases with a microphone for 6 cents.
28. Subscription – If you think of something valuable (newsletter, online magazine, etc.) that you can consistently offer on a certain basis (weekly, monthly, etc.), you may want to offer a subscription service. This could be a fee charged each time your product is sent out or on a monthly basis. Either way, this has to be something that your customers can only get by subscribing to your website.

I know this post is a few months old but I stumbled onto an app called Quickthoughts, a survey site. Unfortunately they only give out Amazon gift cards. You redeem them every time you hit $10 which is shockingly easy because every survey if you qualify pays $2 and then id you don’t qualify they credit you .10. I was skeptical because I hit 10 bucks in less than 2 hours and have cashed out 4 $10 Amazon gift cards .i took a screen shot as proof but not too sure how to post or if I am able my current valance is 5.70 doing a few short surveys just today.

– Project Payday is one of those sites that has testimonials of people who have earned thousands of dollars by getting paid to get trial offers. I’m not saying you’ll earn thousands, but it is legit and you can earn some extra cash. They assume that by paying you to do a free trial, you’ll either like the product and purchase it, or forget to cancel the trial and get charged for it. If you can keep track and cancel before you get charged (if you don’t want the product), then this is a great site for making some money.
Clearly, there's a lot of demand on Amazon, and if any product is going to sell, it's going to sell well on Amazon. But the goal here is to source the right products that will easily sell at the world's largest online retailer. Generally, products between $10 and $50 sell very well here. Just be sure to do the right market research before jumping on this bandwagon.
Now you’ve got many different options to start earning online. If you saw something that really interests you, try it out and learn more about it. If you’re really wanting to make a full-time income online, you need to be dedicated to learning how to do what you want to do. There are tons of free resources out there. You just have to search for them!
I just began blogging in 2017 and my first dollar was also from affiliate marketing. But the more experience I get, the more I’m realizing that long-term success probably won’t come from looking for products to promote, and then finding an audience – but rather finding problems to solve, building and serving an audience, and only then, promoting my own or others products that fit. There may be shortcuts, but I’m not sure how sustainable they are?

You’ve probably noticed I write a lot about automation because it can increase productivity and profit. Huge online retailers know this, too, and they automate everything they can. But even in this age of artificial intelligence, some things still require a human being. Such things are called human intelligence tasks, or HITs, and you can earn great money completing them online through portals like Amazon’s Mechanical Turk (4).
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.

Take it seriously. Yes, you’re applying for an online job. Yes, you can do the work in your underwear, but that doesn’t mean it’s not a “real job”. You must treat it as such or they aren’t going to treat you as a serious candidate. You aren’t the only one who wants to work in their underwear. In fact, the competition online is likely higher than it is in your local area.
