Depends on what kind of website you have.
Before, when Justin TV is still up and running before it became Twicth, I used to stream a live sports events there, with my website url embedded on the video and a description saying "watch it on HD on my website" or something like that and I'm getting like 10k visitors in just an hour. I have millions visitors on that website and I'm getting lots of income via adsense. It's an old technique but those where the days.
You can still do it on youtube but organic traffic is the way to go.
