I have about 30 videos published, but only one that has any kind of volume - you can actually see how much you make on each video over the last four weeks (or other selected measurement periods).
There are some guys on CB that make thousands each month. Not me. I am around $75 a month, but expect it to tail off as my videos age, especially the one video - it is two years old now. I made a mistake not signing up for revenue, so I think I was close to 150,000 views before I got paid anything.
