Which statement correctly describes CPM in cost-effectiveness measurement?

• A. Cost Per Thousand People
• B. Cost Per Message
• C. Cost Per Thousand
• D. Cost Per Million

Answer: (C)

The concept tested is understanding what CPM represents in media cost measurements. CPM stands for Cost Per Mille, with “mille” meaning thousand, so it measures the cost to reach 1,000 impressions of an audience with a message. This unit—1,000 exposures—lets you compare how expensive it is to deliver the same amount of reach across different channels or campaigns, regardless of how many individual people actually see it. It’s about cost per thousand impressions, not per person or per message, and not per million. That’s why Cost Per Thousand is the correct description.
