Bidvertiser actually is a nice alternate for google adsense.
You can manually approve ads you only want to appear on your site.
Thus you can turn down Low CPC/ CTR ads depending on their bids (you'll be able to see it on the ad status). Unlike on adsense, GA's point system controls the ads that will show up based on the category of the site, keyword/ keyphrase etc.
You should choose the category (on bidvertiser) accordingly. If you have a business site you should put it under business categ. Otherwise they might disable the ads on your site.
So far I'm earning atleast $500/ mo from it (on 1 site I own) with mearly a 1000 UV/ 3000 PV per day and gets it directly to my paypal ($10 or more).
