From reporting to reality
An ad platform records a conversion. That doesn’t tell you whether the customer would have bought anyway. MTA sees touchpoints, but can miss the influence it couldn’t track.
Calibration uses incrementality evidence to adjust that credit. Your total revenue stays the same. The share attributed to each channel changes.
Grounded in experiments
Start with Dema’s experiment benchmark. Bring in tests from your own business. See the evidence behind the estimate, including the uncertainty.
Then choose your calibration factor. It stays explicit, with a separate setting for each channel, funnel and market that needs one.
How incrementality testing worksA range of evidence.
One explicit setting.
Your calibration, in plain sight
Choose the reporting source. Review the evidence. Set the multiplier. Explore the example below to see exactly how a channel’s attributed revenue changes.
Each channel, funnel and market can have its own calibration.
Retain 60% of the reported revenue for this channel. A different base needs its own calibration.
Bring it back to profit
Revenue is only part of the decision. Product margins, fulfilment and returns change what you keep. Read calibrated performance alongside contribution after advertising.

Higher margins. Fewer returns.

Lower margins. More returns.
Illustrative economics. Both examples have €30,000 in calibrated revenue. Contribution is after product, fulfilment and return costs, before ad spend.

Questions
Causal attribution uses evidence of incremental impact to calibrate recorded attribution. In Dema, causal factor attribution applies an explicit multiplier to a chosen baseline: ad-platform reporting or multi-touch attribution. Experiments help you assess that multiplier. The result is an evidence-informed allocation of channel credit, rather than treating a recorded touchpoint as proof that an ad caused a sale.
Multi-touch attribution divides credit among the touchpoints it can observe. It does not, on its own, establish what would have happened without the advertising. Dema can use MTA as the baseline, then calibrate its attributed value using incrementality evidence. You can also choose the ad platform as the baseline. The appropriate multiplier depends on which base you choose.
Dema shows a distribution informed by finalized incrementality experiments, together with matching experiments from your own business. Its Bayesian model combines benchmark evidence with your results. You review the distribution and experiment evidence, then choose an explicit multiplier for the relevant channel, funnel and market. A benchmark is a starting point; it is not the same as a test of your own business.
It means the calibrated channel value is higher than the selected baseline. For example, €20,000 multiplied by 1.20 becomes €24,000. This can be appropriate when the evidence suggests that the baseline under-credits a channel. The multiplier is relative to the chosen base, so a factor for ad-platform reporting cannot simply be reused for MTA.
No. It changes how revenue is attributed. When calibration reduces paid-channel credit, the difference is redistributed to the channel groups selected in your settings, such as Direct, Backfilled or Search Organic. Total revenue remains balanced. The illustrative €50,000 → €30,000 example changes channel credit; it does not remove €20,000 from the business.
The multiplier applies to the selected attributed value. When you calibrate conversion counts and keep spend fixed, CPA moves in the opposite direction: 50% of the conversions means twice the CPA. For profit decisions, look beyond revenue to contribution after product costs, fulfilment, returns and advertising. Equal attributed revenue does not imply equal profit.
Incrementality tests estimate what changed because of advertising and help inform calibration. Causal factor attribution applies that evidence to channel reporting. Marketing mix modeling takes a broader view of the mix and supports budget planning across channels. They work together, rather than being interchangeable measurement methods.
