man, do you remember back in the day when facebook was just click, test, scale? those were the days. now its like every pixel has a secret handshake and you need a phd in data science just to figure out why your ads die overnight. i was running a simple skin care offer, pushing on facebook, got CR up to 4.5% on sleeper lp, cpa was hanging around 15, everything smooth. then ios 14+ hit like a freight train, and suddenly, what used to be a no-brainer just turned into a guessing game. so i shifted over to tiktok, tried some native style creatives, and it's weirdly working better than fb for now, cr is climbing, cpa's holding. but man, remember when google ads was just search and a bit of display? now it's like trying to solve a Rubik's cube blindfolded with all these auto-bids and smart campaigns. still, gotta say i miss those simpler days. now it's like, you gotta be a hacker, a designer, and a data scientist just to get a stable week. anyone else nostalgic or is it just me holding onto old memories?
