FAQs
ROAS (Return on Ad Spend) = Revenue / Ad Spend. ROI = (Revenue − Total Cost) / Total Cost. ROAS ignores non-ad costs (product cost, fulfillment) while ROI gives a complete picture. A 4:1 ROAS may still mean negative ROI if margins are thin.
Google estimates an average of $8 revenue for every $1 spent on Google Ads (8:1 ROAS). However, this varies enormously by industry. A profitable ROI depends on your margins — a 200% ROI on 80% margin products is very different from 200% on 10% margins.
