Which scenario best illustrates using ROAS to assess campaign efficiency?

• A. When you want to measure website uptime
• B. When you want to measure revenue generated per dollar spent on ads
• C. When you want to track email open rates
• D. When you want to compute customer satisfaction

Answer: (B)

Return on Ad Spend (ROAS) measures revenue generated for each dollar spent on advertising, so it directly gauges how efficiently a campaign converts ad spend into sales. The scenario that best illustrates this is measuring revenue per dollar spent on ads. For example, spending $1,000 on ads that drive $5,000 in sales yields a ROAS of 5x, showing how effectively the ad spend is turning into revenue. The other options relate to uptime, email open rates, or customer satisfaction—metrics that don’t directly reflect how ad dollars translate into revenue. Remember, ROAS focuses on revenue relative to ad spend and doesn’t capture profit margins or other costs.
