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. 
Today, if you're at all serious about succeeding in any endeavor, whether online or offline, you have to deliver enormous amounts of value. Yes, you have to do the most amount of work for the least initial return. This is especially true online. Why? Because it takes time to build authority and create an audience, two primary ingredients necessary to succeed in the wonderful world of commerce on the web.
Set up a merchant account. Service businesses in the past had to generally rely on cash or check—setting up an entire credit card processing system was a thankless, expensive task at best. Using a service such as PayPal makes it possible to accept virtually any form of credit or debit card for your services, and includes dispute resolution should the need arise (and it will arise).
Once you download the app and create an account, you’ll need to link a debit or credit card to start earning. Whenever you shop with one of Drop’s hundreds of partner brands, you’ll earn points. In addition to the points you earn for shopping, you can earn more rewards for completing simple tasks. Every friend you refer is worth 1,000 points. You can also earn additional points for integrating other apps or completing a Linked or Mobile offer.
Starting a podcast, like making a YouTube channel or blog, comes down to telling interesting stories and building an engaged audience. I’m probably sounding like a broken record by now, but you need a niche that you’re interested in and there’s already a demand for. Come up with a list of topics you’d like to talk about and then search iTunes charts, Google Trends and other podcast research sites to see what’s currently out there and popular.
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.
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.
The best part? You get to put a smile on someone’s face — and you get paid to do it. Though exact wages will vary, Instacart Shoppers can earn as much as $20 per hour. If you committed to a typical 40-hour workweek, your compensation would come in at just under $40,000 per year (without taking into consideration expenses like gas and wear and tear on your vehicle).
If you want to help shape digital products in their early stages, joining an online focus group or answering survey questions is a great way to make extra money online. They don’t pay as much as some of the other options we’re highlighting in this list, but you can join groups on sites like Survey Junkie, User Interviews and InboxDollars that pay out through PayPal, check or even Amazon gift cards. You’ll be asked to provide a bit of information about your personal demographics (age, location, etc…), but after that you can get going making money online through completing surveys.
However, this only further illuminates the exponential rise of online business today. Considering that the internet is still largely in its infancy, as the modern conveniences give way to near-instant delivery of products via drones, 3D printing and other means, and as virtual and augmented reality help to improve the online shopping experience, nearly all our commerce will eventually be conducted through online channels rather than offline channels.
Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others. If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.
Pay-per-click advertising is the easiest way to get traffic to a brand-new site. It has two advantages over waiting for the traffic to come to you organically. First, PPC ads show up on the search pages immediately, and second, PPC ads allow you to test different keywords, as well as headlines, prices and selling approaches. Not only do you get immediate traffic, but you can also use PPC ads to discover your best, highest-converting keywords. Then you can distribute the keywords throughout your site in your copy and code, which will help your rankings in the organic search results.
Check with your local bank to see if they're giving away cash bonuses for opening up accounts. Banks run promotions like this all the time, so grab some real cash quickly if you're in need. It won't break the bank (no pun intended) but it will give you a quick $50 or $100 -- maybe even more -- when you really need it. You might need to deposit a minimum amount of cash (usually in the thousands) in order to qualify for these types of accounts (but not always).
Sign up for a reputable affiliate network: Aside from Amazon, there are dozens of top affiliate programs for bloggers and even large reputable affiliate networks, such as Share-A-Sale, Clickbank, and Skimlinks, that specialize in connecting you with merchants who are looking for affiliates to sell their products. They charge relatively low commission fees for the privilege of connecting you with merchants, and the merchants on these sites tend to offer much higher commission percentages or set dollar amount payouts.
Join a startup accelerator: Another great option is to apply to a startup accelerator like Y Combinator, 500 startups, or TechStars, where a group of investors will help coach you, connect you with potential partners, and provide startup cash in return for a small stake in your company. The competition is tough to get into these, so don’t rely on them as your only path forward.
While Etsy is fantastic for handmade goods that you’ve already created, if you’ve got killer designs that would look good on phone cases, t-shirts, or even wall hangings, pillows, and duvets, you can sell them on Society6 without paying anything to start.

That means one design can be used to make a whole range of awesome products that are printed and shipped on demand whenever someone buys from you.

The music industry might not be as strong as it was in the 80s, but there are still plenty of ways to make money online as a musician. Sites like SoundBetter let you sell your services as a songwriter, producer, or session musician to thousands of customers a month. While Musicbed, Music Vine, Marmoset, and SongFreedom are perfect for licensing your music to TV shows, movies, and web series.
If you’ve got some free time and don’t live in the middle of nowhere, becoming a Lyft driver can be a very lucrative side hustle. And right now, they’ve got a promotion going on where any new driver can earn up to a $1,000 bonus after completing their 125th ride. If you start now and hustle hard on the weekends, you can probably unlock that bonus within a few weeks of driving (the bonus is cleared on top of your normal earnings).
