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.
Now, I know what you’re thinking. Most of the software and apps you use on a regular basis are made by massive companies or established development studios. Well, yes. But many successful apps, particularly those in the Apple and Google stores, are created and marketed by individuals and small businesses. In fact, independent developers made $20 billion in the App Store in 2016 alone.
17. Amazon – Have you heard of FBA? It stands for “Fulfilled by Amazon” and it’s getting pretty popular. Basically, you buy products (in bulk is best) and ship them to Amazon for them to store. When your products sell, Amazon packs them up, ships them out and sends you the money (after taking their cut). There are people making a full-time living from FBA, while others just do it for some extra money.
One nice thing about Elegant Themes too is that instead of paying for every theme separately you simply pay one yearly subscription fee and then get unlimited access to all of their different themes. So if you intend to set up several different websites and want some solid themes that are guaranteed to be continually updated and worked on these guys are definitely work a look.
As long as there is still the written word, there will always be editors. Freelance editing and proofreading not only pays a decent hourly wage, it also gives you the chance to read about potentially interesting topics too. What's more, pursuing freelance writing & editing as a business idea can afford you a lifestyle that lets you travel the world as a digital nomad. You can find lots of job postings from companies and individuals in need of writing, proofreading, and editing services on Contena, which makes this a high-demand opportunity to make money online.
25. Products – You can create your own product, such as an ebook or computer software. You would then use your blog as a promotion tool to get people to buy your product. As long as you create a legitimate product with a whole lot of value, you should be able to get some buyers, but like everything else with a blog, you’ll need the traffic to get the sells.
Understand how a niche website works. A niche website focuses on very targeted, specific information. The content must be specific, useful and interesting to your target audience. Successful niche websites get anywhere from 1,000 to 10,000 visitors per month. You build content on a particular keyword, and you make passive income with Google Adsense or through affiliate links.
For Pinterest you can just sign up, create an account and can start posting out images along with a link back to your website. One of the cool things about Pinterest is you don’t even need many followers to actually start getting traction. It all relies on how good your images look. You can see some of the images that I’ve posted out from my numerology site have gotten a lot of traction and I don’t even have that many followers on there:
18. CraigsList – Some things don’t ship very well. Other things may make you feel uncomfortable to sell to someone across the country. Anytime you’re selling a large item or something you just don’t want to ship, Craigslist is a great place to go. It’s simple to list your item (again, take good pictures!). If you don’t like the idea of putting your phone number out there, the interested individual can send you a message to your inbox without even getting your email address.
First of all, I’m not saying you MUST host your website at ClickBank. But if you’ve started building website using their Builder tool, it’s hard for you to move it somewhere else, not because they hold “hostage” to your website. It’s because the contents are built in such a way that it can only be shown properly using their Builder. When you move your website to somewhere else, you have to spend a lot of time re-doing all the content to make it look visually appealing. You get my point here? This is just like many other content/page builders. Once you stop using the plugin, your content is no longer readable.
Long-tail keywords are search phrases, rather than one or two words. If you are planning to promote an online poker course for example, you might do some keyword research and decide that the term "online poker course" has too much competition from existing websites, but articles based on things like "When to push during a sit-n-go" don't have as much competition and may yield more traffic.
Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
So many people dream of writing a book, but never go through with it. Yet no matter what, I’m sure you have experience and value you could give through writing a book. By packaging your skills and knowledge into a downloadable eBook that helps people learn a skill, advance their careers, or start a businesses, you can change someone’s life and even make good money online. You'll just need to employ an easy tool like Sellfy in order to quickly sell PDF files (like an eBook) to your readers.
