A CFO wants to compare the ROI of YouTube against TV and offline media. Which measurement solution provides this even comparison?
Correct Answer
Marketing Mix Model (MMM)
Why is this the correct answer?
The solution is a Marketing Mix Model (MMM). MMM uses aggregated historical data on spend and outcomes across every channel — digital, television, radio, print, out of home — with statistical modelling to estimate each one's contribution to sales. Because it relies on aggregate data rather than user-level tracking, it can put YouTube and offline media on the same footing, which digital attribution cannot: attribution depends on measurable interactions, and there is no click on a television advert. That is why MMM is the standard answer to a CFO-level question about comparable ROI across all media. Its limits are worth knowing too. It needs a long history and spend variation to work, produces channel-level rather than campaign-level answers, and is usually run periodically alongside attribution and incrementality tests rather than instead of them.
Why are the other options wrong?
Brand Lift
Brand Lift measures attitudinal change from digital campaigns through surveys. It cannot compare ROI across offline media.
Search Lift
Search Lift measures additional search activity driven by a campaign, which is a narrow digital measure.
Unique Reach
Unique Reach reports deduplicated audience reach, not return on investment across channels.
Real-world example
A retailer's MMM covering three years of spend finds television driving 22% of sales and YouTube 14%, with YouTube returning more per pound at current spend levels. The following year's plan shifts budget accordingly — a comparison no click-based report could have produced.
