Once you have that problem or need nailed, the next step is to validate that idea and make sure you’ve actually got customers who will pay for it. This means building a minimum viable product, getting objective feedback from real customers, incorporating updates, testing the market for demand, and getting pricing feedback to ensure there’s enough of a margin between your costs and what consumers are willing to pay.
Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs. 
Today, pretty much any business can benefit from some form of social media presence, whether that’s just a Facebook page or a full-on suite of streams including Pinterest, Twitter, and Instagram as well. Learning each of these websites involves an investment of time and attention that not every business owner is ready or willing to give. That’s where you come in, if you are skilled at using these platforms: become their Social Media Manager! Most of us have spent plenty of time on these platforms, so why not put your knowledge of hashtags and what makes a post popular to work? You should also know to develop a solid social marketing strategy and provide customer service.
The audiobook industry is booming, yet only 5% of books ever get made into audio format. If you’ve got a background in acting, or if people have said you’ve got a voice made for the radio, you can make extra money recording audio versions of independent and popular books. Sites like ACX connect authors with audiobook performers. So, whether you’re an author looking for more ways to sell your book, or an actor/voice actor looking to make some extra income, you can sell your services online.
Online business is how I’ve made a living since 2003 and what has helped me retire early.  I make over $20,000 a month through my blog. You can create your own blog here with my easy 15-minute step-by-step tutorial.  You can start a blog for as little as $2.95 a month (less than a cup of coffee!).  Create a blog and leverage it into affiliate sales or product endorsement deals. Consider topics like:
You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service, refunds and so on. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. Sound like a lot of work? Sure, it is. Especially if you do it all on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not. 
Matched Betting (not available in the USA) enables you to gamble (nearly) risk-free. I say nearly as there is always room for error! It involves placing bets on all outcomes of an event, using free online bets given out by the Bookies. Although it may take a while to get your head around the concept, Matched Betting can make a substantial addition to your monthly income.
Equally, you can charge businesses to ‘claim’ their listing, a method used by many large directory sites like Google Business and Yelp. This involves companies paying to upgrade their listing and adding information such as their web address, social media links, images, and more. Other revenue streams include charging for ad space, adding affiliate links and even charging for services and products on your directory site.
Another great way to make money online is to take paid surveys.There are a lot of companies that pay you to share your opinion.You simply answer questions about their products and services, and they pay you.A lot of people think that all paid surveys are scams.Actually that is not right.If you want to find quality and legitimate survey sites and start making money today, follow my tips.1)Join ONLY legitimate and free survey sites.You can find them on Google, but DON’T type broad keywords like “surveys”, or “paid surveys”.Instead, try something more specific, like “paid surveys with free registration” or “how to find legitimate surveys for money”.That way you will find better results.2)NEVER share your credit card information or your SSN.3)Try to find more information about the survey companies you plan to join by typing “YourSurveyCompanyName” + scams, forums, review.That way you will find more information about every site, you are interested in.4)Join several free survey companies.That way you will make more money.Hope that helps.
I’m leading with this category because I believe article writing is one of the best ways to get started making money online if you’re new to the game.  It costs nothing, and you can be up and running within a matter of minutes.  There is a learning curve (especially with respect to SEO and researching keywords) and you’ll need to be patient, but in time, this can be a significant source of passive income.  Not sure of what to write about?  I’ve discussed that before. Note: These are not listed in any particular order.
The market for drones is expanding. Companies hire out work like aerial inspection, photography and land mapping. So if you’re already a drone enthusiast, why not put your aircraft to work? You first need to register it with the Federal Aviation Administration and obtain a license from them for commercial use. Then, you can apply for gigs as a drone pilot. Learn how to start making money with drones.
They often expect you to commit to working a certain number of hours per week, which is generally part-time. They will pay you an hourly salary for that work, so it is really more of an at home job situation than it is in an entrepreneurial way to make money online. Still, if you want to get involved in political activity, and you have the time and motivation, this could be a way to monetize that passion.
Prior to that group, they had an online community for teachers looking for lesson plans. That probably sounds pretty random, but it's crazy the type of communities you can build and rally people around. If it's something that you're passionate about yourself and you want to connect with others that have that same passion, then an online community is something you should definitely consider.
Thanks for the list Eric. Many of these I have tested out and a few I still work on with regularity. There are many more places to join and get paid to write if one wants to become a full time freelance writer. A few places are Bright Hub($15 for an article), Textbroker(varies from .01 a word to .04), and The Content Authority(roughly same as textbroker). These are probably the easiest to get started with.
Just like you can turn a profit on sharing your skills online, you can also do so using your knowledge. There are a variety of sites out there that will pay you to do research, answer questions, or be an on-call expert in a number of different industries. Have a nursing degree? You can pick up some extra cash when you’re off duty by answering medically-related questions. Off-duty handyman or plumber? You can do the same thing with home improvement questions. If you just enjoy researching, you can pull in some cash by doing research through a website like Wonder.
