Level: Advanced
These two major measurement approaches answer similar questions in fundamentally different ways, and understanding when each is genuinely appropriate prevents relying on the wrong one.
Multi-Touch Attribution Works at the Individual Level
This approach depends on tracking individual user journeys across touchpoints, which makes it vulnerable to the same tracking and privacy limitations affecting browser-based measurement generally.
Media Mix Modeling Works at the Aggregate Level
This approach analyzes overall spend and outcome patterns over time using statistical modeling, sidestepping individual tracking limitations but requiring substantial historical data and modeling expertise.
Many Sophisticated Operations Use Both Together
Combining the granular, real-time insight of multi-touch attribution with the privacy-resilient, big-picture validation of media mix modeling often produces a more complete and more trustworthy measurement picture than either alone.
Next step: Use the Sales Letter Writer to whichever measurement approach you rely on, remember both are ultimately measuring the effect of your actual creative — invest in strong copy regardless of which model you're using to evaluate it.
