Why does scaling kill my campaign performance?

Scaling pushes the system into less efficient inventory and broader audience. If your conversion loop is weak, CPA rises fast.

This issue is common among Meta advertisers and usually indicates a structural or optimization problem that can be resolved with the right approach. Understanding the mechanism behind the problem is the first step to fixing it.

This problem typically stems from one or more of the following:

• Check whether CVR drops after scaling or CPM rises first
• Increase budget gradually and keep edits minimal
• Scale by creative supply, not only by budget

Follow these steps to identify the root cause:

1. Check whether CVR drops after scaling or CPM rises first
2. Increase budget gradually and keep edits minimal
3. Scale by creative supply, not only by budget

Once you've identified the cause, apply these fixes:

1. Start by identifying the root cause using the diagnostic checklist above
2. Make one change at a time and wait 24-48 hours to see results
3. Document what you changed and the outcome for future reference
4. If the issue persists, consider reaching out to Meta support with specific details
5. Use the quick fix page for immediate action items
