Summary
This episode demystifies incrementality, a critical concept for ecommerce operators to understand truly effective marketing spend. It clarifies how to differentiate between correlation and causation in ad performance, helping brands identify where their next marketing dollar will generate the most profitable, incremental growth that wouldn't have occurred otherwise. The discussion emphasizes moving beyond basic attribution to focus on causal impact and optimize for genuine business contribution.
Key takeaways
Incrementality measures where the next dollar is best spent to drive profitable, incremental contribution that wouldn't have otherwise occurred, focusing on overall business contribution rather than channel-specific attribution.
GeoLift tests use holdout or scale groups to measure the incremental impact of ad dollars, providing a causal link between spend and outcome, as opposed to correlative relationships.
Implement an incrementality factor (a multiple) against platform-reported ROAS to get a more accurate "incremental ROAS." For example, if Meta ROAS is 1.5 and incrementality is 200%, the incremental ROAS is 3.0.
Re-evaluate incrementality multiples quarterly for core channels (e.g., Meta, Google Search/PMax) via GeoLift tests to account for changes in product mix, market conditions, and other variables.
High incrementality on a channel like Meta (e.g., incremental ROAS close to 3x) suggests that maximizing spend within that channel through new creatives, angles, and audiences might be the highest impact activity for the brand, rather than immediately seeking new channels.
