I think it will affects the navigation and delay site loading though if it is 15-20 second or less it can be work out.
I got some adsense clicks from it and it gives a lot of traffic however I'm not sure if it's worth the money it costs in the long run
Wait. Are you meaning as a publisher or as a advertiser? I think some people are confused by the looks of this thread
For publisher, Valueclick media (IF YOU CAN). Else adbrite is best Advertiser, stick with adbrite as they are used often. But it is only worth it for some sites.
Thank you for the advice. It's not cheap but I noticed that after choosing specific channels my average viewing time went up to 260 seconds so it's not bad
dude adbrite ads r lil cheap but dey don't ban u ......u will earn more cash from dat fullpage ads ......according 2 me....bcoz i hav tried it and i suceeded also.....
