You're running a campaign and want to assess the ROI. Which conversion column within a given report would show you the ROI for a campaign?

The Conversion value/cost column is the correct selection because it provides a direct calculation of return on investment (ROI) by dividing the total revenue generated by the total amount spent on the campaign. While "Conversion value" shows the gross income and "Cost per conversion" measures efficiency in acquiring a single lead, only the Conversion value/cost metric—often referred to as Return on Ad Spend (ROAS)—tells a marketer exactly how many dollars in value were returned for every dollar invested, making it the essential KPI for assessing true profitability.
