You should try to recruit both SFI affiliates (PSAs) that people who shop from TripleClicks.
It would be better SFI affiliates because they are more likely to gain once they reach the state of EA and you gain all the months that they maintain it.
Regarding TripleClicks it has the gain only when people make purchases, so if for some months do not buy anything, do not even have the percentages of gain.
Good job
