Click Apply to save all column changes
Success🎉
Your Ads Manager now displays:
NC Purchase (Total) - Number of new customers acquired
NC Purchase (Cost) - Cost per new customer
NC-ROAS - Return on ad spend from new customers
⚠️Important: Initially, no NC Purchase data will appear in Ads Manager because Meta does not support attributing custom conversions from the past. Data only populates for conversions occurring AFTER setup.
