Which metric is a clear indicator of digital promotion effectiveness?

• A. Manufacturing throughput
• B. ROAS (Return on Advertising Spend)
• C. Supplier lead time
• D. Inventory turnover

Answer: (B)

Measuring how well digital promotions perform comes down to how efficiently ad spend translates into revenue. ROAS (Return on Advertising Spend) does exactly that by showing how much revenue is earned for each dollar spent on ads. A higher ROAS indicates that the digital promotion is effectively driving sales relative to the investment, making it the best indicator of promotional performance and a useful basis for optimizing campaigns, channels, and creative.

The other metrics relate to different parts of the business: manufacturing throughput starts with production capacity, supplier lead time focuses on procurement speed, and inventory turnover concerns stock management. While these can be affected by demand shifts, they don’t directly measure how well digital promotion converts spend into sales.
