If you've just started getting purchases (e.g. 2 so far), you're still in the very early learning phase—so the key is to scale gently and strategically, not aggressively. Here's how to approach it:
1) Duplicate the Winning Ad Set
Keep the creative and targeting the same.
Increase the budget slightly in the duplicate (e.g., 20–30% more).
This helps you scale without resetting the learning phase in the original.
2) Test Single Interests in Separate Ad Sets (Optional but Useful)
If you're using stacked interests now, try splitting top-performing ones into individual ad sets to see what works best.
Don't overdo it—focus on 1–2 high-potential audiences.
3) Avoid Big Budget Jumps in Original Ad Set
Never increase budget by more than 20% at once in the same ad set—it resets learning and may hurt performance.
4) Monitor Purchase Data Daily
Wait for at least 5–10 purchases before making major scaling decisions like shifting to CBO or Advantage+.
