Ever since the idea of online auctions came into existence, the online selling market has been on the rise. Many are interested, but don’t know how to get started. There are still all kinds of ways to make money by selling online, whether you’re selling what you already have or buying and selling like a store. Before we get started, here are a few general tips when selling anything online:

If you’re not ready to go through the complex process of setting up a full online business, you can make a little easy money by filling out online surveys or doing paid micro-tasks, like odd jobs on Amazon’s Mechanical Turk website. You can also try selling some items on eBay or putting a few designs up on a free CafePress account to try to make a little side income. With any of these approaches, it may take some time for you to get any payout!
Now, I know what you’re thinking. Most of the software and apps you use on a regular basis are made by massive companies or established development studios. Well, yes. But many successful apps, particularly those in the Apple and Google stores, are created and marketed by individuals and small businesses. In fact, independent developers made $20 billion in the App Store in 2016 alone.
And while it will take time to build up a big-enough audience to attract advertisers and other ways to make extra income from your podcast, the opportunity is there. John Lee Dumas interviews entrepreneurs seven days a week for his podcast Entrepreneur on Fire and now makes more than $200,000 a month from it. In fact, John publishes all his income online and showed that he’s made almost $13 million since launching in 2012.
But cutting costs only goes so far. Unless you already make a lot of money and spend like a bon vivant, most people can’t eke out that much more from their budget by decreasing expenses. Plus, the more you retrench, the more your quality of life suffers. (It’s all relative, though — certainly some overspenders could actually improve their lives by tempering their expenditures. Here are 101 ideas for saving money.)
28. Subscription – If you think of something valuable (newsletter, online magazine, etc.) that you can consistently offer on a certain basis (weekly, monthly, etc.), you may want to offer a subscription service. This could be a fee charged each time your product is sent out or on a monthly basis. Either way, this has to be something that your customers can only get by subscribing to your website.
As the internet grows and expands, not only is SEO going to get more competitive, but it's also going to grow more lucrative. You could quite easily capitalize on this industry if you know what you're doing. This doesn't just go for doing work for clients, but also for yourself. You could launch any number of online businesses, niche websites, and blogs with the right amount of SEO skills. 
Even in the age of automation, some jobs still require a human touch. Companies often outsource those jobs via services like Amazon’s Mechanical Turk. These jobs can be tedious — tagging images, transcribing videos, classifying receipts — and can take anywhere from a few minutes to a few hours. Pay depends on the task, and the person requesting the work gets to approve the finished product before paying you. That can leave room for scams, so do your research and join a community like TurkNation, which can steer you away from shifty dealers. Read more about doing tasks on Mechanical Turk.
