What does a media audit company do?

A media audit company independently examines how an advertiser’s budget is planned, contracted, purchased, delivered and reported. The work sits between finance, procurement and marketing: financial records establish what was paid, platform data shows what was delivered, contracts define what should have happened, and business data tests whether the reported outcome was real.

A credible media auditor does more than review campaign settings. The engagement should reconcile spend, verify performance, examine fee and incentive structures, test governance controls, and document each finding with evidence. Our paid media audit services combine those disciplines in one fixed-scope engagement.

Selection criteria

Six tests for an independent media audit firm.

Independence is not a line in a proposal. It is visible in how the firm earns money, obtains evidence and reports its findings.

No media buying

The auditor should not earn more when your media budget grows or benefit from recommending additional spend.

Direct evidence access

The team should obtain read-only platform data, contracts, invoices and source-of-truth business records rather than auditing presentation slides.

Financial quantification

Each material finding should show the affected spend, the evidence, the root cause and the practical financial consequence.

Written methodology

The testing approach, limitations and review process should be clear enough for finance, procurement and an audit committee to challenge.

No software dependency

The conclusion should not depend on buying a dashboard, licence or retained service from the company that performed the review.

Partner accountability

Senior practitioners should own scope, judgment, internal review and the final stakeholder readout.

Media Audit Group

Our operating model is designed around independent assurance.

01

Structurally independent

We do not buy media, take agency commissions, accept platform rebates or sell optimisation software.

02

Finance-grade evidence

We reconcile platform, invoice, contract and business records so conclusions can be traced back to source evidence.

03

Fixed-fee projects

Scope and fees are set in the engagement letter. Compensation does not change based on what we find or recommend.

04

Written conclusions

Clients receive a report, supporting schedules and a partner-led readout—not another dashboard to monitor.

Questions to ask before appointing a media auditor

  • Does the firm buy, manage or resell any media it may be asked to review?
  • Will it obtain platform and financial records directly, or rely on agency-prepared reporting?
  • How does it distinguish platform-credited revenue from incremental business impact?
  • What evidence must support a finding before it reaches the final report?
  • Who reviews the work, and who presents the conclusions to senior stakeholders?
  • Does the engagement end with a report you own, or lead into a software or media-management sale?
