Shopify discount incrementality: did the offer create the order?

A discounted order proves that a purchase happened. It does not prove the discount caused it. Here is the measurement approach that separates the two.

FOLLOW THE QUESTION

Three ways to go deeper.

A receipt, a red discount tag and blue accounting tokens sit beside an empty counterfactual path.
