For most webmasters it’s all about getting the sponsor converting, if they don’t convert well, they are history. I’m not saying thats exactly a bad plan, but here’s something else to think about…
Over the years one thing I’ve noticed about some sponsors, while they might be tough to get that first sale with the surfer, on the other hand, they can recur quite well. In the long run, numbers of rebills that keep on going can be a nice steady income. Some sponsors are just better at keeping members than getting them on board.
So before you blow off that sponsor because they might not be selling off the bat, look at your rebills or think about giving them a longer run.
I’m not saying to waste your traffic wad on a crap sponsor, just something to think about.

I second that thought — I look at the reoccurring at what I am sending uniques wise — the higher RPC — the more traffic I send
So, if a sponsor has a horrible reoccurring — its RPC will reflect it
