not really. I have sites getting 1,000 uniques a day that make more through affiliate programs than other sites getting 100,000+ uniques a day do. it's all about the quality of the traffic. generally though when the traffic is high quality there are better things to do with it than adsense/ypn.
I don't think this is possible unless you know someone there - however, ad blocking is definitely the way to go.
I know people that have done 2x that in 1 day for over a month. I am not going to say if I have ever done it myself, but it is very possible.
YPN has stated several times that they have no way to "tweak" ad serving an a per site or publisher basis. They are open to feedback, but any changes affect all publishers. You can use their targeting, blocking, and adjust content on your site.
No you won't. 5 x 365 = 1.8. You won't get anything close to a Yacht for that much - espacially when you count in running and crew costs.
Very valuable information, thanks for sharing. My click through rate is terrible right now so I am looking for anything to improve it.
They also wouldn't mind finding 1 fraudulent click and stripping you of the $150k revenue you earned that month :-D It's happened
