Freelance writing is such a great industry to get involved in if you want to work remotely. There’s plenty of work available and it’s typically one of the most flexible gigs in terms of scheduling. (You can often do the work whenever and wherever you choose.) Even better, it’s pretty easy to get started with a degree or previous writing experience.

Specifically, this subreddit has a great, stickied list of sites and services you can use to make a little extra cash. I recommend reading through it in its entirety and thinking about what makes the most sense from a time/reward standpoint—as well as your personal preferences. You might actually enjoy filling out a ton of surveys, say, over dealing with researching and finding new Mechanical Turk projects to complete.
This next category is one of my favorites. And, it applies to almost everyone looking for a good side hustle. Why? Because it is something everyone should be doing regardless of whether they are looking for a little something to earn a few pennies during commercial breaks that requires minimal effort or they are looking to create a full-time income from home.
If you are really short on cash and need some immediate funds then you should start by looking around your house. Clear out your cupboards and find any items lying around that you don’t need or haven’t used for a while. Then sell them on eBay. Just because they are gathering dust in your cupboards, doesn’t mean someone else won’t snap them up. Simply sign up with eBay, list your products and then, as they are sold, send them off to the buyers.
In today’s world, there are hundreds of ways by which you can make money online and I have personally tried many of them. In the process of doing so, what I have observed is that earning money online is not that tough. In fact, anybody can earn money online when we talk about short term. But when it comes to earning money from the same method to a longer period of time, then it becomes really tough. It might sound contradictory but it is actually true.
Your camera's lens cap spends more time off than on. Being behind the camera and capturing everything from nature to the food on your plate is one of your favorite pastimes. You could be selling your photos online. Digital cameras and the Internet make it easier than ever for you to sell your photos. Upload your photos to sites like Fotolia, Shutterstock, iStockPhoto and DreamsTime. Their compensation plans vary by site but the concept is the same ... you earn money when someone purchases and downloads your photo.
People are turning to audio and visuals when it comes to technical subjects. However, you should consider doing an ebook first and turning it into an audiobook through a resource like Audible's ACX platform. You can hire a producer either through a royalty share program, so you don't have to shell out upfront cash, or you can do a pay-per-hour hire as well.
You can set up a website, gradually build up the content (articles, videos, podcasts, etc.), then eventually monetize the site through advertising, affiliate marketing, or even the direct sale of specific products or services. Even better, you can generally find whatever services and technical assistance you need online and free of charge. Later on, when your site develops a reliable cash flow, you can begin working with paid providers who can take your blog to the next level.
A site called User Testing will actually pay you a fee to evaluate websites. It typically pays you $10 for each video that you review – which typically takes about 20 minutes. If the work is there, and you are particularly good at it, you could earn up to $30 per hour. That’s a pretty solid pay rate for a work-at-home job. You wouldn’t have to work a whole lot of hours to generate a decent part-time monthly income.
Blogging has become a popular medium of earning in the past couple of decades for those who possess exclusive writing skills.

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. 
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
