I used to have a blog that was specifically about making money tips, years ago. But, there are others out there to help you do that. And, I don’t want to suggest that making money should be a primary goal. I’m at a point in my life where I will accept less money for more freedom and doing things I enjoy. But, I have collected a few over the years that I use from time to time, and I wanted to suggest them to friends and more to make money on the side, as well.
Uber/Ubereats/DoorDash/Lyft - any of these will work if you like to drive. Ubereats is my primary use of time, as I like it and makes the most of my options… I choose not to do Uber passengers like I used to.. tho that does make more. You apply via the driver app and are an independent contractor, setting your own hours… you can do this just for a trip a day, if you want, or less.
Usertesting- you click on options that are there to see if you qualify. If you do, you can make 10 dollars for 15 minutes of speaking aloud as you view a page or do a task. https://www.usertesting.com/
Amazon Mturk/ Prolific- answer questions or do small tasks for money.. Amazon has more tasks, but you need to understand how to download and use their extension and prolific pays more. https://www.prolific.com/ Mturk
Swagbucks - also can warn for answering questions, but harder to qualify. But, you can also earn for buying things, entering contests, viewing clips, and more. https://www.swagbucks.com/
Appen - Australian company that works with major us social media companies.. you apply for projects, and if you qualify can earn 10 dollars an hour doing tasks.. but pays a month after work and can end suddenly. https://connect.appen.com/qrp/v2/services/onboarding/sign-up
Ibotta - money for buying specific groceries and such https://home.ibotta.com/
So, that’s just a few. Hope it helps.
