Credit is one thing.Impact is another.

Separate credited conversions from the additional outcomes caused by advertising.

THE SHORT ANSWER

Separate credited conversions from the additional outcomes caused by advertising.

Define the question

Attribution assigns credit under reporting rules. It does not by itself show that a conversion would disappear without the campaign. Incrementality asks a causal question. Google distinguishes attributed conversions from differences measured between exposed and control groups in Conversion Lift studies.

Plan before observing

For a proposed experiment, write the decision first: would additional purchases justify expanding this campaign? Define the outcome, eligible population, duration, and decision rule. Check whether the control group can encounter the campaign elsewhere and document overlapping promotions.

Report uncertainty

Low volume or noisy data can leave a study inconclusive. That is not automatically evidence of no effect. In a weekly readout, separate observed performance, experimental evidence, and proposed actions. Strong attributed revenue can coexist with an unresolved experiment; keep both statements visible.
