The three-level structure
| Level | What you set | Example |
|---|---|---|
| Campaign | Objective | Conversions |
| Ad set | Audience, budget, placement | Broad + Advantage+ |
| Ad | Creative + copy | Video or carousel |
Keeping one objective per campaign and letting the ad set use broad, AI-driven targeting is the modern best practice.
Targeting and creative in 2026
Manual interest targeting has weakened as signals have become scarcer, so the 2026 approach leans on broad targeting plus AI to find converters, and creative volume to do the persuading.
“The audience is the algorithm’s job now. Your job is the offer and the creative — make those great and let Meta find the buyers.” — Priya Sharma, AdsMG AI
