You can sell your ebooks through Amazon's Kindle program or Apple's iTunes Connect, which gives you access to a large majority of the digital-book reading market and the barriers for entry are incredibly low.

More and more businesses are recruiting social media managers to run and organize all their social media. And to save money, social media employees are often employed as online freelancers.
If you're looking to address some immediate financial needs, then the app economy is likely right for you. Thanks to the global sharing phenomenon, launched in part by our smartphones and ever-burgeoning global connectivity, you could easily opt for some quick active income by using well-known apps. From ride sharing to deliveries and even quick tasks, there's an app for that today, as the saying goes. 
While you play, the app works in the background and transfers small sums from your checking account into a high-yield Blast savings account based on “triggers” you set — things like the number of opponents you defeat or enemy bases you destroy. You can earn extra cash by completing “missions” that allow you to test new games or take familiar games to the next level.

If you have decent writing ability (no, you don’t need a journalism degree!), and knowledge in a few specific topic areas, you can be one of those writers. It’s an opportunity to make money online and without ever leaving your home. It’s also the kind of venture that can start out as a small side business, but grow into a full-time career.
Don't sacrifice morals for a quick buck — At the outset, you'll want to do all sorts of things to make money online, but don't sacrifice your morals for a quick buck. Not only will you put people off, but you'll lose Google's trust. You also shouldn't concern yourself with things like Adsense or other ads on a blog before you have around 100,000 visitors per day. Yes, per day. 
Online business is how I’ve made a living since 2003 and what has helped me retire early.  I make over $40,000 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.

There are a variety of tasks that you may be asked to perform. This can include delivering documents, delivering food or restaurant meals, taking pictures of a building for a real estate developer, taking pictures of a menu in an upscale restaurant, or even delivering auto-parts.

More than half a billion products are sold on Amazon every month, making it an incredible opportunity to make money online. But, like everything else that involves making money online, you have to do quite a bit of work to earn it. One option on Amazon is to find products that are already made and buy and sell them at a discount.

One factor that you must be aware of though is that Care.com is a peer-to-peer arrangement. That means that you will be in direct competition with other pet sitters in your area. You must price your services competitively in order to get business. Once you begin to develop a list of regular clients, you will be in a better position to raise your rates. This will be particularly true as you get referrals from those customers.

You could be paid for sharing a business’s information, recommending restaurants or hotels, or tweeting pictures of you using or wearing products.

26. Services – You can offer a paid service, such as life coaching, blog coaching, goal setting or financial planning. Just be sure to investigate all the legal implications and make sure you’re not claiming to be a professional if you’re not one. With a service like this, you’re basically using your blog to sell yourself. You’ll need to convince people that you’re worth buying and then be able to back up your claims once they purchase your service.
No matter what method you select for generating your online income, there's one very important thing to understand. Today, across this globe, with its 7+ billion inhabitants, there are two recurring things that people are looking for more of. Either people want more time or they want more money. The truth?
