Oh, bless your heart for thinking complexity equals sophistication.
Honestly, the reason people keep crawling back to simplicity is because Meta's algorithm after Andromeda turned into a chaotic little gremlin that loves shoving 90% of your budget into one random ad set and then wondering why nothing works. Fragmented budgets with a dozen ad sets? That's just feeding the machine conflicting signals and watching it panic-spend into a corner. At lower budgets especially, you're basically asking the algorithm to solve a Rubik's cube blindfolded.
Worked with a fashion brand burning through €50-ish a day. They had five ad sets with audience splits and creative combos because someone read a blog post about "testing everything." Meta kept concentrating spend unpredictably, CPAs bounced around like a ping-pong ball, and no ad ever got enough data to stabilise. Collapsed it into one campaign, one broad ad set, one creative system (text variations plus related media). Two weeks later, cost per acquisition went from around €38 down to about €19, and conversions actually looked like a trend instead of a seizure.
So - do you already have a creative angle that's proven itself, or are you still fishing for that winning message in a sea of "maybe this will work"?
