Where is our media spend being wasted?
Media spend waste hides in three places: non-working spend (fees, tech taxes, and made-for-advertising placements), poor frequency management (paying to show the same ad to the same person past the point of impact), and ghost conversions (broken attribution crediting ads for sales they didn't drive). Independent audits — including the ANA's programmatic transparency study — suggest 15–30% of typical budgets produce no incremental value.
Key facts
- The ANA's 2023 programmatic media study found roughly 23% of programmatic spend goes to made-for-advertising sites and other low-value inventory.
- Only a fraction of each programmatic dollar reaches working media after fees and tech costs — the ANA traced as little as ~36 cents of value per dollar in worst cases.
- Ghost conversions from broken attribution cause platforms to scale budget into audiences that were converting anyway.
Why waste stays invisible
Platform dashboards grade their own homework: they report the conversions they claim credit for, at the frequency they chose, on the placements they selected. Without independent oversight, automated bidding happily optimizes toward low-quality signals and non-incremental conversions.
The three leak points, in order of size
First, non-working spend: supply-path fees and low-quality inventory, worst in programmatic. Second, frequency waste: uncapped campaigns hitting the same users 20+ times. Third, attribution ghosts: view-through and last-click credit claiming organic sales — which then misdirects next month's budget.
How to run a spend audit
Go beyond platform metrics: pull placement-level reports and check for MFA domains, examine frequency distributions per campaign, and reconcile platform-reported conversions against CRM or transaction data. The audit typically takes days and finds double-digit percentage savings.
When to use a third party
Internal teams are often too close to their own account structures to see the waste — and sometimes disincentivized to report it. A neutral third-party audit of spend and tracking health is the standard fix, usually paying for itself in the first month of recovered budget.
Frequently asked questions
How much media spend is typically wasted?
Independent audits consistently find 15–30% of budgets producing no incremental value — through supply-chain fees, low-quality inventory, excess frequency, and misattributed conversions.
What are made-for-advertising (MFA) sites?
Websites built purely to harvest ad spend — high ad density, clickbait traffic, minimal real audience. The ANA found roughly 23% of programmatic impressions land on MFA and similar low-value inventory.
What is a ghost conversion?
A conversion the platform claims credit for but didn't cause — typically via generous view-through windows or broken tracking. Ghost conversions mislead automated bidding into scaling non-incremental audiences.
