Your campaign structure determines everything—how budget flows, how the algorithm learns, and whether you can scale. Get it wrong, and you're fighting the platform instead of leveraging it.
After managing $100M+ in Meta ad spend at MBell Media, we've tested every structure imaginable. Here's what actually works in 2025.
The Hierarchy: Campaigns, Ad Sets, Ads#
Campaigns hold your objective and budget (if using CBO). Ad sets hold targeting, placements, and optimization. Ads hold creative. Each level serves a specific purpose.
The Recommended Structure#
For most accounts: ASC Campaign (60-70% budget) for broad prospecting. Manual Campaign (20-25%) for creative testing. Retargeting Campaign (10-15%) for warm audiences. See our ASC guide.
Common Structure Mistakes#
- Too many ad sets (fragments budget, prevents learning)
- Overlapping audiences (bidding against yourself)
- No clear testing vs. scaling separation
