Another seemingly free site you can make money from is Wikipedia. People who say it’s easy to edit Wikipedia have clearly never tried editing Wikipedia – it’s a pain. Thankfully it’s a pain for companies as well, so many of them are willing to pay editors to assist them in the editing process. You’ll become a bounty hunter in a way, choosing your own lines to cross and keep. If editing is something you like to do, and you’re willing to put in the work it takes to learn Wikipedia’s dispute process, roll up your sleeves and try this one out.
Creating and selling courses on your blog can be a successful way to make money online. The course itself should be relevant to your blog, and based on a topic that will benefit your audience. Although it may take time to create the course in the first instance, once completed, you can then repeatedly make money from the course each time you sell it.
Ebay is a bellwether. It's been around since nearly the start of the online boom. But, like any other platform, success can seem fleeting if you don't know what you're doing. Selling items on eBay, professionally that is, can be an art form. Getting people interested in your auctions isn't always easy, especially when there's hefty competition and low demand for what you're selling.
It’s one of the oldest and most proven ways to make money – buy low, sell high. The buy low part comes from searching garage sales, estate sales, and even thrift stores to find items that are in good condition (“gently used”) but selling well below what they would if they were brand-new. In this way, you might be able to acquire an item for $5, and later sell it for $50.
