Last year I decided to make an experiment with youtube. I wanted to check out if I was able to earn money with it and get some values regarding how many views/clicks are neccessary to get some money.
To do so your youtube account have to qualify for monetarization / Youtube Partner Program.
Your channel have to have at least 10.000 views to qualify for this.
After activation of the monetarization program you have also to create a AdSense Account and link it with your Youtube account. After this you need to enable monetarization for your videos and hope for some clicks. If you reach 70€ they pay:
After this experiment I can say in 2017 – 200.000 monetarized views on your videos generates about 80€
