for gambling site i think you need to try affiliate and CPM ads.. because you can earn from CPM if you dont get anything from affiliate.... always use 2 or 3 different options to earn money... trust me on this.. and you will earn from any one...
Due to recent screw ups with adbrite.. i Highly recommend bidvertiser. I ditched adbrite and went to bidvertiser. Making a lot more money I am always paid 30th of every month by bidvertiser.. There not scammers at all. Do some research people.
Well I can say its all depending on the niche. On the thread case, he wants to monitize his gaming which I think adbrite is better.
Bidvertiser dont even have good amount of advertiser,they usualu show their own ads again n again, There is no comparison between adbrite and bidver. So go for Adbrite.
It is depend on your CTR and impression. If you have high traffic with low CTR, go for adbrite. If your website have low traffic, then choose bidvertiser.
I have experementing this on my site. after 2 weeks. adbrite gives me $7 and guess what bidvertiser give??! it is solid egg figure $0!
+1 for Adbrite. Been using them for the past 4-5 months and have been making mid-high $XXX each month. Two thumbs up for them.
