Media investment reviews: from delivery to the next decision

A media investment review answers four questions: what was approved, what ran, what the business recorded, and what the evidence supports next. Keep delivery, supplier-credited response and business outcomes separate. A favourable dashboard figure does not settle whether the investment worked.

Reconstruct the investment

Start with the approved brief, booking versions and spending ceiling. Record market, offer, intended audience, channel roles, flight dates and outcome definition. Add dated changes to spend, targeting, creative and availability. Review the campaign that ran while retaining the original plan, so deviations remain visible.

Use one cost basis. Show media, directly required services and production separately, in AUD with the GST treatment stated. Distinguish commitments, actual charges and unresolved credits. This establishes the investment being judged; detailed invoice reconciliation belongs in the commercial close-out.

Record	Question it answers
Approved plan and changes	What was intended, and what changed?
Delivery and coverage	Did the bought activity run for the intended audience and period?
Channel response	What did each supplier record or credit under its rules?
Business outcome	What did the organisation record under the agreed definition?
Evidence limits	Which comparisons remain uncertain or unavailable?
Decision	What will change, and when will it be checked?

Key Elements to Include in a Media Investment Review

Approved plan and changesDocument all modifications to budget, targeting, creative, availability
Delivery and coverageConfirm placements ran for correct audience and duration
Channel responseRecord supplier-reported activity under their rules
Business outcomeUse agreed definition; include duplicates and exclusions
Evidence limitsIdentify unverifiable or unavailable comparisons
DecisionState action, amount, reason, owner, effective date, next check

Compare delivery with the intended opportunity

Check placements, dates, spend and audience coverage against matching plan fields. A reach forecast is an estimate for its specified settings; it is a delivery commitment only if the agreement makes it one. Delivered reach may be modelled or unavailable. Compare like units, populations and periods, and show missing audience evidence as missing rather than zero.

Interpret a variance against the channel's job. A buy can meet its impression target while concentrating exposure among fewer people than intended. Another can run on schedule outside the useful service area. Record the affected line, measurement limit and practical consequence before choosing a response.

Approved Plan vs. Delivered Activity: Key Differences

Placements: Check against planned dates and locations
Spend: Compare approved ceiling with actual charges (GST included)
Audience Coverage: Match intended demographic to delivered reach; show missing evidence as 'not available'
Delivery Timing: Ensure flight dates align with original plan; note deviations

Explain the result without double counting

Present the agreed business outcome once, with its source, period and treatment of duplicates and exclusions. Put channel delivery and supplier-credited actions beside it as diagnostic evidence. Suppliers may use different conversion windows and counting rules; more than one report may credit activity connected to the same customer. Adding those figures does not produce a unique campaign result.

Build the account in time order: activity, offer availability, recorded response and business outcome. Include material changes such as a price revision, stock gap or broken enquiry path. Distinguish an observed change from a claim that media caused it. Estimating additional outcomes requires a suitable comparison method and its assumptions.

Identify evidence gaps

A poor measured outcome and poor evidence are different findings. One channel may have delivered valid activity but few accepted enquiries. For another, the intended placement, audience or outcome may be impossible to check. For each evidence gap, record the affected spend where it can be identified, the missing link, whether it can be recovered and the decision it prevents.

Do not call untracked sales zero sales. Equally, a measurement gap does not excuse a placement shown to have missed the brief. The review can identify a delivery fault while leaving its business effect unknown.

Assess platform-related context

For a review involving digital platforms, distinguish campaign results from wider evidence about consumer and competition risks. The ACCC’s tenth and final Digital Platform Services Inquiry report, published on 23 June 2025, said Australian consumers and businesses continued to encounter harmful practices across a range of digital platform services.

The ACCC reported that 72 per cent of Australian consumers surveyed had encountered potentially unfair online shopping practices, including accidental subscriptions or hidden fees. This is a national survey finding, not a campaign performance measure; do not use it as a target or as evidence that a particular campaign caused harm.

The report described manipulative design practices, such as interfaces directing people to more expensive subscription or purchase options. Where relevant to the campaign, record whether the customer journey involved these kinds of practices and whether they could affect the interpretation of response or business outcomes.

The ACCC also cited examples of small businesses losing access to customers when an account is deactivated, or facing a fake review on a search engine or marketplace. If such an issue affected the campaign, include its timing and practical effect in the decision record rather than treating platform-reported activity as the whole account.

ACCC Survey Findings on Digital Platform Risks (Australia, 2025)

Consumers affected by unfair practices: 72%
Small businesses impacted by account deactivation: Reported cases exist

Use wider evidence carefully

The ACCC’s consumer survey found that 82 per cent of respondents agreed there should be a specialised independent external dispute resolution body for digital platform services. This indicates concern reported by survey respondents; it does not establish a campaign-specific result or determine the appropriate media investment decision.

The ACCC administers and enforces the Competition and Consumer Act 2010 and other legislation. A media review can flag a platform or customer-practice issue for appropriate follow-up, but should not present a campaign performance finding as a legal conclusion.

Using ACCC Survey Data in Media Investment Reviews

Pros: Highlights systemic risks in digital platforms that may affect campaign performance
Cons: Not campaign-specific; cannot be used as direct performance evidence or legal justification

Make the next investment decision

For each channel, record a dated action: maintain, reallocate a bounded amount, retest a specific uncertainty or stop future spend. State the evidence behind the choice. Check commitments and the receiving channel's capacity before moving money. If the proposed decision depends on additional business caused by a channel, use an appropriate effect estimate or make a smaller decision supported by the available evidence.

Close with the action, amount or scope, reason, owner, effective date and next check. Carry unresolved questions into the next brief.
