Ok so I've been using adbrite for a while now. I have a decent site with loads of hits and a very cheap cpc rate (you can see this here . http://site.www.adbrite.com/mb/commerce/purchase_form.php?opid=124752 I've only sold cpm ads though, I don't get why no one is buying. Please help.
Your average of 11 cents for cpc is okay.. although for some markets that is too high. I did a quick check in one of my areas and found a $3.93 cpc. I would likely chalk that up to limited data, but the overall stats would not have me rushing to buy ads on your site.
Your site looks great, but the thing that would not turn me off to not want to advertise specifically on your site is the ad text is too small. If the design permits, I would make the ads a little larger, or you could try to place them horizontally and see if that works. I catch my eyes looking down instead of going right.
What if you try to purchase an ad on your own site? Does it work? You won't lose money as you can unapprove it - I'm suffering the same problem with no publisher ads showing when I know they should be showing/
