I'm not sure what the percentage is for the revenue share for Bidvertiser, but AdSense currently share 68% of the revenue. - So I'm inclined to think AdSense are pretty damn decent. The last time I used Bidvertiser, let's just say, they wasn't the best in my opinion for a number of reasons:
- Ads were never targeted that well, due to their lower amount advertisers, in comparison to AdSense for example.
- Clicks were always, always low in value
Those two points are enough to steer clear and stick with the market leader; which is AdSense.
