bruh so i just realized if u wanna really crush it u gotta look at the data like a hawk. first, check the cr and epc on each offer like every day, if cr drops more than 10 percent from yesterday gotta rotate creatives or try a different geo. then look at the source stats, not just overall, split by device and OS, sometimes android is killing it while ios is dead or vice versa. also pay attention to the flow of clicks, if a bunch of clicks come in but conversions stay flat or drop, time to change the lp or the creative angle. trust the data, don't guess. if u see a sudden spike in CTR but no conversions, maybe the offer's dead or the traffic isn't qualified anymore. just simple stuff but man it's a once u get used to it. totally helps me keep my campaigns profitable instead of just throwing money at randoms.
