I also participate in online surveys through the following websites, that work in the US and internationally (I use them all and I'm based in Brazil, for example) - Opinion Bureau, Myiyo, and Green Panthera. All of them have a variety of surveys and pay well. All you need to make money is to have 20 min or so to answer a few questions every day/week and have an active Paypal account so you can cash out.
If you live in an area where Uber or Lyft operate, why not become a driver? If you're looking to make some short-term cash, you can definitely rake it in by working for one of these popular car-hire apps. As long as your vehicle fits within the specifications of their program, and you have a clean license, you could do this on the side, especially if you're in a crunch for cash.
Leanne, that was great stuff. I saw some interesting delineators I’d never seen before, like how many subscribers you have making a difference in whether you should start with affiliates, at what level, etc. I appreciate the “ethical” angle you weaved throughout this, too, because affiliate marketing can/does have a bad reputation due to the way it’s been abused in the past. Your article will help educate current and future affiliate marketers, much appreciated!
