My Advantage+ Shopping performance dropped. What do I change?

ASC performance drops trace most often to creative exhaustion, another campaign competing in the same auction, or a structural edit that triggered re-calibration.

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 creative performance breakdown — which are getting spend?
• Check for overlapping manual campaigns competing in auction
• Check edit history for changes in past 14 days

Follow these steps to identify the root cause:

1. Check creative performance breakdown — which are getting spend?
2. Check for overlapping manual campaigns competing in auction
3. Check edit history for changes in past 14 days
4. Check Audience Segment breakdown for existing vs new customer split
5. Compare CPM week over week for seasonal competition

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
