Tipss..hmm.. too be frank.. i don't have much tips to be given.. it just good sites having some good traffic..and kontera giving fixed CPM for the traffic. Thats it. So, if you also have some big sites and you think your visitors will convert well, you can run them and may be after seeing the performance of 4 or 5 months, you can talk to them about fixed CPM rates.:d
I dont use Kontera so I am not sure about this. It is an in-text ad network so you think it can work on a file hosting site with traffic and content? We need to talk to em to get the fixed cpm? Great going. Good Luck
Adbrite ads look just like Adsense. Isn't this against Google TOS? I am wanting to try them but a little worried.
