remember when we just looked at EPC and cr and thought we were crushing it? now every network throws 20 metrics at you and half of them are fake or useless. i've been burned more times than i can count by weird inflated stats that looked good on paper but vanished once you dug deeper. my advice is focus on the real numbers - conversions, epc, payout delays. always ask for raw data, see if the numbers make sense with your traffic. some networks cook the books with ghost clicks or fake leads. keep it simple, test, scale, repeat. don't fall for shiny reports, verify every stat before you go big.
