Which metric directly measures the value gained per unit cost for conversions?

• A. Impressions
• B. Click-through rate
• C. Interaction rate
• D. Conversion value per cost

Answer: (D)

Evaluating how efficiently your ad spend translates into value is captured by conversion value per cost. This metric divides the total value generated from conversions (such as revenue or assigned conversion value) by the total cost of the ads, giving you value earned for each unit of currency spent. It directly answers how much value you gain per dollar spent, which is the essence of profitability and return on investment. Impressions measure exposure, not value; click-through rate and interaction rate gauge engagement but not the value returned per unit cost. So conversion value per cost best reflects value gained per cost for conversions.
