I'm going to be honest and it may not be an answer you like but it is the truth: it's going to require real work.
Websites that are most likely going to be posted here as answers by other users like Swagbucks will not make you easy money, haha.
You need to approach making money online seriously and start a business. I am currently making decent money through affiliate marketing so I can confidently answer this question.
The real ways to make money online are going to take real work to get there and it WILL be an uphill battle...most people can't get themselves to do the work without seeing any result in the beginning which is why 99% drop off and fail to make a dime...
I've been doing affiliate marketing full time for 3 months now. The first month I made...get this: $0. I was uploading and editing a video every single day to YouTube. Last month I made $300. This month I am closing the month at $1,000, and expect to hit $1,600 - $2,000 for June, then over $3,000 for July.
It takes real work and sacrifice but anyone can get there. Model the successful people and follow a system that works.
And no matter what you do - do NOT invest in courses and "shiny objects" because you are only making other people money by doing so!
Sometimes you just have to be real. I know this wasn't the answer you were looking for but there isn't a "push a button and get rich" system that works ANYWHERE. It just isn't real.
The nice thing is that once you get over that hill, you can outsource/automate most of your business very cheaply and it then only takes up a small fraction of your time. But in the beginning you are going to be working like a dog.
