How to use it
Step 1: Channel role
Finish by deciding what changes, what stays the same and when the result should be reviewed again.
Step 2: Spend
Work through the checks in the order the task happens. Mark missing information instead of filling the gap with an assumption.
Step 3: Leads
Finish by deciding what changes, what stays the same and when the result should be reviewed again.
Step 4: Conversion
Start by writing the current state without trying to improve it. That keeps the review anchored to what actually happens today.
Step 5: Decision
Record the part that changes the decision, then attach an owner and a date to anything that still needs evidence.
What a useful result looks like
Finish Marketing Channel Audit with an owner and a review point so the record does not become a static worksheet. Review each active channel by cost, role, conversion path, measurement quality and contribution to the current growth target.
Common mistakes
Leaving ownership undefined and assuming the next person will pick up the work.
