19. eBay – Of course you can’t read an article about making money online that doesn’t mention eBay. You can start an eBay store and get serious about it or you can just sell some stuff to declutter your home. Either way, I’ve made my fair share from selling on eBay and it’s still a popular way to earn money. If you decide to start an actual eBay store, you’ll want to find a drop-ship business like Doba that will store and ship items straight to your customers so you don’t have to deal with an inventory.
As my blog audience grew I began to test a method of making money I was very interested in – affiliate marketing. My first test proved positive, though initially I was disappointed that of my readership of 500 or so people (at the time), I could only sell one or two products, making $20 commission each. It wasn’t retirement money, but it was a start.
Mechanical Turk is a great way to make some extra cash. You probably won’t make much more than a few dollars an hour, but it’s also dead simple to complete many of the tasks. Most tasks take less than a minute to complete and pay a few pennies. If you do a lot of MTurk, it could add up to at least some fun spending money. Sign up for free, then complete qualifications to earn access to higher-paying tasks.
Set up a roadside stand. Depending on where you live, you could profit handsomely by setting up a roadside stand. If you live near a resort area, for example, you could buy cases of bottled water, put them on ice, and sell them to passers by for twice what you paid. Selling fruit and produce you grow yourself is also a smart idea in highly-traveled areas.
Rather than making money through subscriptions, YouTube channels are based on a traditional advertising system. Meaning the more viewers you get, the more you make. Once you’re approved for the YouTube Partner Program and can start including ads on your videos, with every 1,000 views, you will make approximately $2-$4. Which might not seem like a lot, but if you have 100 videos with 5,000 views a month each, that would be $1,000–$2,000 already. Just imagine if your videos start hitting millions of views!
SwagBucks PayPal gift card redemption is definitely not instant. Their website says it can take up to 10 business days. I have cashed in several PayPal gift cards with them and it could take anywhere from 24 hours to the full 10 days to receive them. About 5 business days seems to be most common. Don’t get me wrong…I love earning with SwagBucks. But Paypal payment is definitely not instant.
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. 
If you design a wildly popular app (which is harder than it sounds), you might be pleasantly surprised with the income they generate. Offering one or more apps at the iTunes or Android app store gives your creations wide exposure to prospects. And income can be generated by charging for the app, displaying in-app ads, or charging for in-app features and upgrades.
Cryptocurrency or digital currency is the next big thing in currency trading. It’s a digital asset that is used as a method to pay for things, that isn’t run by a government or institution. Bitcoin is the most well known digital currency and was trading at $200 per Bitcoin back in 2013. Now it is worth over $17k and is expected to be worth well over $1m in 2022.
Salvage and resell. Do you love antiques or have a knack for finding valuables at flea markets or yard sales? If you do, it might be time to consider salvaging items for resale – or even scouting out antiques to sell for a profit. While you’ll need to spend quite a bit of time searching for prospects and spend some money buying upfront, you could easily turn a profit if you know what you’re doing.
It’s something akin to picking stocks. You want to buy undervalued domains, and sell them later on at a higher price. For example, you can pick a domain that is out of favor, but could be related to some future event. So if you decide that the stock market is likely to crash in the future, you can buy a domain that includes the words stock market crash during a rising market, and then sell it in a falling market.
