Guys, I'm using Plugrush and I've an average CPM of $6-$7. Is it good considering that I'm using Plugrush or is there a way to scale it up. It used to be around 9, but lately it has taken a dip. If it's less, please throw in few recommendations you would like to suggest. I'll work on them immediately. Thank You! BTW: I use Lordsen's tumblr + Plugrush method.
