I also use InboxPounds, a site where you earn for web searching, completing surveys, doing small tasks, reading emails, playing games, and more. I use InboxPounds for searching, instead of using Google, and earn money for each completed search. You can also visit the site for offers a few times a week and complete tasks. You can cash out using Paypal as well.
The peer-to-peer concept is coming to virtually every corner of human existence. That includes the hospitality industry. Through AirBnB you can actually rent out your house for various lengths of time for a predetermined fee. That gives you an extra income on your house and gives the visitor the benefit of having an entire house, rather than being crammed into a single hotel room.
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.
Last but not least, you can also earn money online by building an online community, although the monetization strategies you can pursue will vary a lot depending on your goals. You can build a community with a blog, for example. You can also build an online forum and charge people for membership. You could even build up a Facebook group and use your influence there to sell and promote products.
eBay is the most popular global auction site around and is a great place to sell items you no longer want. If you are looking to earn some extra cash, start out by looking around your house for things you no longer want; list them on eBay and watch as customers bid on them. You can also purchase clearance sale items and thrift store finds and make a couple dollars profit by listing them as well. The key to selling on eBay is to do your research and find out what the hot items are.
