If NameDrive, Paid near as well as their templates look, they would be great. Unfortuantly, NameDrive's RPC, just isn't very good. Perhaps Ed could tell us why?
In general though, My RPC fluctuates from day to day, Here of late, It has been the lowest i have seen it in a very long time. It will pick back up.
Many times, Advertisers max out their budget, and will not be on a parking page for a few days. then they will return, that brings in the lower budget advertisers. That brings RPC's as low as 0.09 per click in my case. On certain names. They usually pick back up in a couple of days though.
