  • Verify the dates, attribution window and conversion definition for purchase event in this verification checklist.
  • Verify one purchase event cause the evidence can prove or reject.

What to check

At this stage, start with what changed before refreshing creatives. Compare purchase event, GA4 attribution and the business result.

For the next review, attach one observable proof to each completed check. If the numbers do not say what to do next, verify the input before editing.

  • Events are duplicated or missing when reviewing purchase event as a verification checklist.
  • Conversion value is incomplete when reviewing purchase event as a verification checklist.
