Incrementality
The portion of conversions a marketing channel actually caused — as opposed to conversions that would have happened anyway.
Full Definition
Incrementality measures the true causal impact of a marketing channel by comparing performance with and without that channel running. Brand search ads, retargeting, and TV historically claimed credit for many conversions that would have happened organically. Incrementality testing — typically via geo-holdouts or pause tests — reveals each channel’s true contribution.
For furniture brands, brand search and retargeting typically test as the least incremental channels.
Why It Matters for Furniture Brands
Most attribution models over-credit channels closest to conversion (retargeting, brand search, last-click email). Incrementality testing reveals which channels actually drive new revenue versus which just intercept existing demand. Brands that test incrementally consistently shift budget toward upper-funnel.
