I thought "affiliate marketing" sounded familiar and I was right, my son's been doing it for a while now. So what I'll write is what he sent me. He's using
this tool, it's a dashboard where you can see commissions, conversions, sale amount, ECPC (Earned Commission Per Click) for a time range you select. He said I should mention that you can export data to Google Sheets, as apparently, some find this very convenient. You can also check the affiliate link report to see which affiliate links are performing the best. Needless to say, I don't understand any of the things I copied from his message, but I hope it helps, maybe this kind of affiliate dashboard could be what she needs. Good luck to your daughter!
