If you’re crafty (and I mean that in more than one way, wink wink), you’ll enjoy Etsy. Handcrafted items are the bread and butter here. Plenty of people make decent side money on the site, which is basically an EBay for crafters and artists. Set up a sellers account with Etsy, and you’ll be asked to set up your virtual storefront and put up at least 5 goods for sale.
Commercial use requires 'releases' - editorial use doesn't. Stock photos can be sold for commercial (eg, marketing) or editorial (ie, journalistic) use. You'll have more opportunities to make cash if your photos are available for both, but photos containing people or property (including branding and logos) need signed releases to be sold commercially.
If you want to clear some space out in your house and have a big stack of books you’ve been holding onto for too long, you can make money selling your books and textbooks online. Stores like Half Priced Books and others will give you cents on the dollar for each of your current books while you can check what your book is worth by simply entering the ISBN number on Book Scouter.
If you have a knack for organization, you can make money online as a virtual assistant helping people to keep their days in order. A virtual assistant will do everyinthing from bookkeeping to research, database entry, booking travel, and managing email. It can also be an awesome way to rub shoulders with some very important people, build up your professional network, and of course grow another stream of income. You can find great gigs on UpWork, Fiverr, Indeed, and Remote.co.
As someone who has years of experience doing lead generation on a local blog. Getting enough “traffic” for an affiliate site is damn hard. Over the past couple of years, an injury to my foot has left me slightly disabled. Affiliate marketing makes sense for someone like me with prior blogging experience who now has limitations. I will start with one niche and add another site later. I’m hoping to see good results in within about 18 months. But that’s only because I know how to do a lot of things and I know what’s involved. You have to write consistently, work your SEO, pick your poison in social media and be engaged in it. It’s a lot of hard WORK. I feel sorry for anyone who got their site shut down because they didn’t know how to transfer their site to another host. That’s terrible.
