Measurement Design
Part of Media measurement planning
Choosing common business outcomes across channels
Define one countable business outcome for a cross-channel campaign while keeping channel response and delivery metrics in their proper roles.
Choose one outcome the business can define and count once, no matter where a customer saw an ad. Keep each channel's supporting metrics to explain its role. A shared outcome does not require every platform to report the same attributed total.
Define the unit of success
Begin with the decision the campaign is meant to influence. For sales, specify whether the unit is an order, a paid order, a customer or net revenue after refunds. For enquiries, define what makes one qualified and when that decision is recorded. For bookings, decide whether a request, confirmation or attended appointment counts.
Write a rule someone outside the media team could apply to a business record. Include the Australian market or service area, product set, campaign dates and the time allowed for a customer to act. Record exclusions such as cancellations and duplicate submissions. Identical labels can otherwise hide different outcomes.
Choose a source that can count across channels
The business's order, booking or lead system can often provide the combined total, if its records are sufficiently complete for the question. Confirm the agreed outcome can be extracted for the planned period. Until platform conversions and site events are reconciled with that definition, treat them as channel diagnostics.
For a hypothetical trades business, a form submission and a phone call might each become a qualified enquiry after review. The common outcome is the accepted enquiry, with duplicate contacts handled under the agreed rule. Form and call counts remain useful for finding problems in each path, but adding them together could count one prospective customer twice.
Keep supporting measures in their roles
| Question | Measure to define | What it cannot establish alone |
|---|---|---|
| Did activity run? | Delivery and reach where measurable | Business response |
| Did people respond? | Visits, calls or submitted forms | Lead quality or causation |
| Did the business objective move? | Accepted enquiries, bookings or sales | How much change media caused |
The outcome should fit the campaign's time horizon. A short campaign for a product with a long decision cycle may need an agreed intermediate measure and a later business-result review. Label that intermediate measure clearly instead of declaring success on clicks alone.
Before launch, agree on the definition, source, duplicate-handling rule and reporting date with the people responsible for the business record and channel reports. Show the shared business total once in the final review. Use channel figures to investigate delivery and response under their stated attribution rules.
Cross-Channel Metrics: Shared Outcome vs. Channel-Specific Measures
- Shared Business OutcomeAccepted enquiries, bookings or sales (counted once across channels)
- Channel-Specific Supporting MeasureForm submissions, phone calls, visits, clicks (used to assess delivery and response per channel)
- What the Shared Outcome Cannot Do AloneEstablish causation or media impact – only shows business result after customer action
- What Channel Measures Cannot Do AloneProve business success – they show engagement, not conversion or value
