FAQs

See all

What is the difference between incrementality and attribution?

Incrementality testing measures the causal impact of a marketing activity. What would have happened if we hadn't run this campaign? By establishing a counterfactual, incrementality testing measures the additional value generated from the marketing activity.

Attribution assigns credit to different channels and touchpoints. Which channels contributed to this conversion? It distributes credit across channels or tactics – often in the form of views, clicks, or impressions – but doesn't measure if the conversion would have happened without the marketing activity. Attribution doesn't measure causality.

What is the difference between incrementality and MMM?

Marketing mix models (MMMs) are statistical models – often regression-based – that aim to quantify the impact of marketing and non-marketing variables (like seasonality or pricing) on business KPIs (like sales or conversions). Importantly, they use historical aggregated data to feed the model. Traditional MMMs can be helpful in illustrating correlations, but won't explain what caused or will cause business outcomes.

Incrementality testing measures how a change in tactics impacts a change in outcomes. Haus' Causal MMM is built on incrementality test results, meaning it's fundamentally powered by causal data that can provide more accurate recommendations on budget allocation and business decisions.

What is the difference between incrementality testing and A/B testing?

A/B testing compares two variants side by side, measuring which one is more effective. Incrementality gets at the causal impact of a marketing tactic by creating one group that receives the tactic and one group that doesn’t, isolating how business outcomes would differ in the absence of that tactic.

For more on this, we recommend checking out this article.

Can incrementality testing work with offline marketing channels?

Yes. If It's geo-segementable, it's eligible for incrementality testing.

Learn how Haus helps brands measure the incrementality of offline campaigns like billboards, regional, linear TV, store openings, and out-of-home (OOH) activations with Fixed Geo Tests.

How often should a brand be incrementality testing?

Incrementality is a continuous practice. It's not a once-or-twice-and-done thing – because incrementality experiments represent a point in time, you're never "done" testing. There is always something new to test, learn, and optimize. High-velocity testing = more learnings = better business decisions.

Not having an incrementality test running is a missed opportunity to run an efficient business.
