The business

A vertical SaaS company had been running a $1.2M annual advertising budget largely on autopilot since its original launch campaign. The core targeting, placement and scheduling settings had barely changed in years; the account simply kept spending to a plan set long ago, on the reasonable-sounding assumption that a large, established budget was being managed with proportionate care.

What triggered the audit

Efficiency had decayed slowly and, tellingly, no one clearly owned the day-to-day media hygiene of such a large account. The audit ran a full delivery-quality teardown to establish where the impressions were physically going, on the principle that on a seven-figure budget even a modest percentage of waste represents a very large absolute number.

What the audit found

The teardown found an account coasting on stale settings while its delivery quality quietly degraded. Placement targeting, dayparting and geo-controls had never been meaningfully optimized since launch, so a large share of impressions — around 40% — was landing on out-of-hours slots, out-of-market geographies and low-value placements that buyers in this vertical never convert from. None of it was catastrophic in isolation; it was simply budget being sprayed inefficiently, day after day, because the account was on autopilot and no one was watching the delivery detail. On a $1.2M base, that inefficiency compounded into roughly $74k a year of spend reaching inventory with effectively no chance of producing a customer.

How we produced this finding

MarginFix arrived at the media efficiency finding by refusing to take attribution at face value — the SaaS spend was run through the agentic AI audit framework and tested for real, incremental impact, then checked and signed off by a named senior auditor before anything was reported.

Data sources: Spend by channel, campaign, creative and audience, joined to conversion and revenue data.

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: ad impressions hitting no-convert inventory traced line by line and reconciled to recognized revenue in the ledger over a matched period. Line items representative and redacted; the recovered figure is the reconciled audit finding.

What we changed

Rebuilt placement exclusions, dayparting and geo-targeting around exactly when and where buyers in this vertical actually convert, rather than the launch-era settings the account had coasted on.

Cut the long tail of junk and low-value inventory that had been absorbing a large share of the budget while returning effectively nothing.

Established a monthly delivery-quality review with a clear, named owner, so the hygiene gains hold rather than decaying back to autopilot over time.

Reallocated the recovered budget into the high-performing placements that had previously been starved by all the wasted delivery.

The result

$74k a year of wasted delivery eliminated — a 12× return on the $5,950 Audit + Sprint fee — with reach concentrated on inventory that converts. For anyone overseeing a seven-figure media budget, the number is a warning: 40% of impressions were landing where buyers never convert, purely because the account ran on autopilot. On a budget this size, even modest waste is a very large figure, and it accrues every single day nobody owns the hygiene. A structured audit teardown finds it in days, and the monthly review that follows pays for itself many times over.

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