The business

A vaccines and public-health brand ran media campaigns to drive uptake, flighted and targeted on a broad calendar. Eligibility for the vaccine was defined by specific populations and windows, but media planning largely followed general seasonal patterns, so how much spend landed outside the genuinely eligible audience and timing was never closely examined.

What triggered the audit

Media efficiency was weaker than the budget and reach implied, hinting a chunk of spend was reaching people who couldn’t act on it. The audit compared media delivery against the eligible population and the windows in which they could actually be vaccinated, testing how much spend fell outside them.

What the audit found

A significant portion of the media was running outside the eligible-population windows entirely. Because flighting followed broad seasonal habit rather than the specific timing and demographics of eligibility, spend was reaching audiences who either weren’t eligible for the vaccine or were being reached well outside the window in which they could act — impressions that could not, by definition, convert to uptake. The campaign looked active and well-delivered on standard reach metrics, so the misalignment between media timing and real eligibility stayed invisible. Concentrating spend on the eligible population within the windows that matter recovered the waste, which across the campaign amounted to roughly $58k a year of out-of-window media.

How we produced this finding

The eligibility targeting finding here rests on causation, not correlation. MarginFix ran the pharma account’s spend through its agentic AI audit framework, then confirmed the incremental effect with a controlled test — and a named senior auditor signed the result off before it left the building.

Data sources: Spend by channel, campaign, creative and audience, joined to conversion and revenue data — plus a geo-holdout test built to isolate what eligibility targeting genuinely caused rather than what it merely claimed.

Key frameworks: Geo-holdout incrementality testing, Marketing Mix Modeling (MMM) and attribution-correction and inflation-factor analysis, cross-checked against Analytic Partners ROI Genome, Google Meridian and Meta Robyn.

Human validation gate: Every incrementality read is re-run against your own data and signed off by a named senior auditor before it ships — no automated output ever leaves the building unreviewed.

Working paper: media spend outside eligible-patient windows traced line by line and reconciled to territory spend in the finance ledger over a matched period. Line items representative and redacted; the recovered figure is the reconciled audit finding.

What we changed

Realigned media flighting and targeting to the eligible population and the specific windows in which they can actually be vaccinated.

Cut the spend that fell outside eligibility by demographic or timing, where it could never convert into genuine uptake.

Concentrated budget into the in-window periods and eligible audiences that genuinely drive vaccination rather than broad seasonal reach.

Made in-window, in-population delivery a monitored metric, so future flighting tracks real patient eligibility rather than the seasonal calendar habit it had always followed.

The result

$58k a year recovered by spending media only where and when the eligible population can act — a 10× return on the $5,950 Audit + Sprint fee. For any health or eligibility-gated brand, broad flighting is the leak: reach looks healthy while spend lands on people who can’t convert. If your media follows a seasonal calendar rather than real eligibility windows, much of it may be unreachable by definition. A fixed-fee audit realigns delivery to eligibility in days, so every dollar reaches an audience that can actually respond.

From kickoff to signed-off findings: 6 days — inside our fixed 5–7 day window.
