If you learned Meta ads before 2022 and have not rebuilt your approach, you are almost certainly leaving money on the table, or losing it. The platform changed underneath the playbook, and a lot of agencies are still selling the old one.
What used to work
The 2018 to 2020 playbook was about targeting. You found narrow interest audiences, layered them, excluded aggressively, ran many small ad sets with tight budgets, and manually adjusted bids and budgets daily. Creative mattered, but targeting precision was the lever. It worked because the algorithm needed help finding the right people.
What changed
Two things. First, Apple's privacy changes cut the signal Meta received from outside its own platform, so granular targeting and tracking got less reliable. Second, and more importantly, Meta's own machine learning got dramatically better at finding buyers on its own, given enough budget and enough creative to learn from. The result: the algorithm no longer needs you to hand-pick tiny audiences. It needs you to give it room and raw material.
Why the old playbook now backfires
- Narrow audiences now limit the algorithm's ability to find buyers you would never have targeted manually. Broad plus strong creative usually beats layered interests.
- Many tiny ad sets split your budget so thin that no single ad set gets enough conversions to exit the learning phase, so nothing optimises properly.
- Daily manual tweaking resets learning and injects noise. The system needs stable conditions to learn.
- Too few ads is now the number one cause of plateaus. With five ads you give the algorithm five probes into the market; it exhausts them in weeks and costs climb.
What works now
The modern playbook inverts the old one. Go broad on targeting and let the algorithm find buyers. Consolidate budget so ad sets actually exit learning. Stop micro-managing and change inputs deliberately, not constantly. And above all, feed the system creative volume: we test 100+ ads a month on scaling accounts, because creative is now the main lever the algorithm has to work with. The full mechanics are in our Meta ads guide.
The uncomfortable part
You cannot micro-manage your way out of weak results anymore. If the creative is not strong and the volume is not there, no amount of bid tweaking saves the account. That is a harder job than adjusting audiences, which is exactly why the brands that adapt pull away from the ones still running 2020 tactics.
