I suggest using adsense with some good affiliates to get good ROI from your site, one affiliate page can make a good difference in your revenue stream.
eria, you used adsense together with bidvertiser?
if you did, you might be violating google's terms of service
Yeah I don't think bidvertiser or clicksor ads are okay with Adsense or YPN.
well not now, I used it for couple of months, but drop bidvertiser because the reasons already mentioned, and it was then when i launched my first site. that time i was not known for the adsene TOS.
