I'm trying to find a way to use subids for multivariate split tests in prosper. For example: If I run a campaign on POF, maybe I want to use c1, c2, c3, c4 in prosper to track things like age (using the token), buttons, or other variables. Then I can look at the "Group Overview" report and filter by c1 to see how all the ages stack up. The problem is, the CPC data will be wrong. Therefore the ROI will be wrong. I cant figure out how to get a report like this and get an accurate ROI for each age. I can download the report from prosper to excel, but I have no way to get the cost data for each age from POF. It's nice that Prosper can capture those subids, and filter by the values in reports, but it's sort of useless without accurate cost and ROI. Has anyone found a way to do this? I would like to be able to make accurate comparisons by factors other than creative id.
I have the same question.. how to clculate CPC from CPM.. like if I bid 0.71 cpm.. how to put that in prosper where it says cpc??
