Measurement

Incrementality Testing

A controlled experiment comparing exposed and withheld groups to isolate the additional results genuinely caused by a campaign.

What it means in practice

A valid test assigns comparable units to treatment and control conditions while limiting spillover between groups. The measured difference estimates causal lift under the experiment's audience, timing, and campaign conditions.

Why it matters

Incrementality testing helps prevent conversions that would have occurred naturally from being treated as campaign impact.

How it is used

Brands hold back a comparable audience from creator media and compare outcomes with the audience receiving the campaign.

Also called

incrementality, lift testing
