i signed up with adbrite for cpm ads.. but i guess there are no advertisers for my selected category.. instead of real ad, "advertise on this site, powered by adbrite" is displayed.. i dont want that.. do you know any cpm site that will surely display ads for my site.. this is my site.. http://laughreal.com
Wait for 1-2 weeks for ads to come on your site, as advertisers take time to select your site for advertising.
