When even a small budget increase hurts performance, it's a sign Meta’s algorithm is shifting away from your best-performing audience pocket. This is common when campaigns are finely tuned at a specific spend level.
- If you're testing a 5% increase, give it 3–4 days to see if performance normalizes.
- If results stay poor, revert to your original budget—it clearly works better at that level.
- Another option: duplicate the campaign with the higher budget. This lets you test scaling without disrupting your current performance.
