After you have created your query to explore the appropriate data, we recommend testing your data against the following data validation checks:
1. Dimension null checks | Ensure that there are no null values for registration_date, activity_date and any segment dimensions. |
2. Monthly gross revenue check | Group by monthly granularity of date_activity and sum gross_revenue_primary. Check that the total values match your internal accounting and dashboards for monthly revenue. |
3. Monthly marketing spend check | Group by monthly granularity of date_activity and sum marketing_spend. Check that the total values match your internal accounting and dashboards for monthly marketing spend. |
4. Daily active users check | Group by monthly granularity of date_activity and sum active_users. Check that the total values match your internal dashboards for DAU. |
5. Check revenue only on active days | Check that no rows exist which have gross_revenue_primary and no active_users or active_payers (depending on which fields provided). |
6. Check active_users > active_payers | If both fields are provided, ensure that active_users >= active_payers. Check this at a segment level. |
7. Check active_users always smaller than cohort_size | Check that active_users for all instances where registration_date != activity_date is less than active_users where registration_date = activity_date, i.e. cohort_size. Check this at a segment level. |
8. Marketing spend only provided by calendar date | Check that marketing_spend is null when registration_date != activity_date as marketing_spend is provided as a calendar date time series and not at a cohort level by days since registration. |
9. Active user value for first day of any cohort with data in | Check that day 0 (where activity_date = registration_date) has an active_user value if any rows exist with data for the registration_date in question. Check this at a segment level. |
10. Check no activity data before start of cohort | Check that no rows exist where activity_date < registration_date. |
