After setting up conversion tracking, you want to add a column for conversion value per cost. How would that be calculated?

Conversion value per cost is a key metric for understanding the return on investment (ROI) of your Google Ads campaigns. It directly measures how much conversion value you're getting for every dollar spent. Therefore, dividing the total conversion value by the total cost of all ad interactions (clicks, impressions, etc.) accurately reflects this ratio. The other options are incorrect because they measure different metrics: Dividing total conversion value by the number of conversions calculates the average conversion value, not value per cost. Dividing total cost by the number of conversions calculates the cost per conversion, not conversion value per cost. Dividing the number of conversions by total eligible interactions calculates the conversion rate, not conversion value per cost.
