Use a metric dictionary
These are planning definitions, not a claim that every program supplies every data field. Select only measures supported by the actual Shopify and program information available to the authorized team.
| Measure | Numerator | Denominator | Observation rule |
|---|---|---|---|
| Qualification rate | Orders meeting the offer conditions | Orders evaluated under the same offer | Use the same campaign and assessment period |
| Access rate | Recipients with recorded access | Recipients with a benefit made available | Allow a consistent opportunity to access |
| Repeat-purchase rate | Eligible customers with a later qualifying store purchase | Customers in the defined eligible audience | Use the same follow-up period |
| Support contact rate | Recipients who contacted support | Recipients at the relevant program stage | Separate contacts from repeated messages |
| Cost per qualifying purchase | Attributable campaign costs | Qualifying purchases | Use compatible cost and purchase periods |
Keep money and activity in context
Return-adjusted Shopify sales, campaign costs, and support workload belong beside activity measures. A delivery count is not a profitability metric, and card use is not equivalent to another order in the store.
Explain incomplete evidence
If the denominator is unavailable or no customer has reached a stage, report that limitation rather than a misleading rate. When follow-up is incomplete, label the observation period instead of comparing newer recipients with a fully observed audience.
