When Facebook Advantage+ Wins
E-Commerce Brands ($1K-50K Monthly Spend)
Facebook's visual-first approach and detailed behavioral targeting excel for product-focused businesses:
- 38% higher click-through rates for fashion, beauty, and consumer goods

Local Service Businesses
For restaurants, salons, gyms, and professional services:
- Location-based targeting is more precise than Google's radius targeting
