I've been adding Tribal Fusion's pop-unders recently as an addition to skyscrapers. I'm getting a lot of 'TF Direct' popunders, which shows 'N/A' for impressions, clicks and revenue. I'm guessing those TF Directs are for international inventory, but since they have N/A in the Net Rev column, does this mean I'm not getting paid at all for those? Also, I've summed all the pop-under views (the non-TF Direct) from one day and that hardly exceeded 200. I do have a lot of non-US visitors and a lot of returning visitors, but I'm still sure I exceed 10,000 absolutely unique US visitors each day. How does that work?
How is your experience with Tribal fusion skyskapers? Does the revenue compare to AdWords? Are you running affiliate programs side-by-side as well? I'd appreciate your experience.
