Hello good people, I'm new to this site and to website marketing in general. I have a site about sports betting that is quite popular with almost 1000 uniques/day. A popunder, like one of those popus that shows the first time you interact with the site, would be a nice addition to monetize it. But how do you find companies that would want to pay for that kind of advertising? And how much can you expect in cpm income for it? I thought that a betting site would be in a high revenue so it would be worth at least something, but I don't know for sure.
