Summary  
This chapter explains three scaling strategies—vertical scaling by incrementally increasing resources, horizontal scaling by adding parallel units or segments, and creative scaling by diversifying outputs—while emphasizing the importance of gradual adjustments, performance monitoring, and stability checks before and after each change.  

General domain of usage  
Digital advertising campaign management

After a campaign is launched and stabilized, the next challenge is scaling. But scaling too early or too aggressively can destroy Return on Ad Spend (ROAS). **Scaling** is not simply about spending more, it's about **earning more efficiently at scale**.

Ready to scale when:
 - **ROAS or CPA** is consistent for at least 2–4 weeks;
- You generate **15–30 conversions per week** per ad set;
- **Wasted spend** from irrelevant clicks is minimal;
- **Landing pages convert well** on both desktop and mobile;
- **Tracking is reliable**, with no missing data or events.

### Three Ways to Scale Campaigns
1. **Vertical Scaling**: increase the budget on winning campaigns;
2. **Horizontal Scaling**: launch new campaigns or target new audiences;
3. **Creative Scaling**: introduce new ad creatives regularly.
