Let's say I have an offer in Prosper, but with POF I'm targeting different demos and groups, should I somehow separate this in Prosper? For example right now in Prosper I have a campaign called "BB People Meet" - and all my different targeted ads on Prosper are using the same link (but I'm using {age:} and {state:} in the c1 and c2 fields). My question is is this ok to do or should I make new campaigns in Prosper like "BB People Meet 25-30" and "BB People Meet 31-36", etc. or is this not necessary? Hope this makes sense.
I would set a campaign per offer/angle - but not per demo.
As you are doing.
Use the c1-c4 variable and "Group" analyses to analyse additional demo data and ads.
