BM vs MMC vs MCC: pick a stack for media buying
What Business Manager, MMC multi-account packs, and Google MCC each do — and when you need each layer to scale safely.
BM — Business Manager (Meta)
The control layer for Pages, ad accounts, pixels, and catalogs. A verified BM lets you share access safely and stop depending on a personal login.
MMC — Multi-account stack
At Zet, MMC is a pack of several accounts plus a synced BM for buying teams. Goal: no single-account dependency, split budgets, and a spare acc if one is limited.
MCC — My Client Center (Google)
The Google Ads equivalent of a BM: hold child accounts, assign roles, and watch spend.
Suggested stacks
- Small brand: 1 Google Ads + 1 Facebook Ads inside a BM
- Agency: MCC + several BM/MMC, pixel per client
- Aggressive scale: MMC with many accounts, warm rotation, 24/7 monitoring
