What this audit is
A scoped Meta Ads account review delivered in 5 business days. The audit covers five structural layers: Pixel and CAPI event accuracy, audience overlap and signal architecture, creative fatigue cycles, iOS attribution gaps, and placement waste across Audience Network and Reels.
The deliverable is a 1-page written summary naming the top three findings and the priority fix sequence. Optional 15-minute walkthrough call included on request. No retainer attached, no upsell pitch, no obligation to engage further. If the work points to a Pixel fix the agency can ship in a week, that is the recommended path.
What this page covers
Why this keeps recurring
Pixel-only tracking misses up to half of iOS conversions. CAPI is not a nice-to-have; it is the structural fix.
Multiple adsets bidding against the same audience inflate CPM. The audit names overlap above 30 percent.
Audience Network and Reels pull spend that the campaign-level report does not flag. The breakdown shows it.
Frequency above 4 with falling ROAS signals fatigue. Most accounts run on the same hero asset for months.
The pattern in one diagram
Illustrative. The actual visibility number depends on platform mix, iOS share, and event dedup configuration.
FThe framework
Five structural layers. One is suppressing the account. The audit names which one and the fix sequence.
Whether the conversion events the account reports reflect actual revenue. The structural cause of half of "Meta is not working" cases is event misconfiguration, not creative.
Multiple adsets bidding for the same audience inflate CPM and steal each other’s reach. Audience overlap is a structural waste source independent of creative or bid.
Frequency above 4 with falling ROAS signals fatigue. Creative volume is a downstream symptom; the audit reads the rotation rhythm.
Pixel-only tracking on iOS underreports 30 to 50 percent of conversions. CAPI plus Aggregated Event Measurement priorities are the structural fix.
Audience Network, Reels, and Instagram Stories pull spend that the campaign-level report does not flag. Advantage+ obscures placement detail.
The inflection
Stan Consulting · structural observation across Meta reads
Producing more creative for a Pixel that under-reports half the conversions is producing more proof that the agency is busy. It is not the layer that moves the result.Pattern observation · Stan Consulting
Three priorities before more creative
01
Deploy CAPI with correct dedup key.
02
Resolve audience overlap above 30 percent.
03
Order AEM priorities to match revenue events.
The decision question
Meta’s algorithm needs accurate signal to optimise. Bad signal means even great creative compounds slowly. The audit names the signal gap.
Where the gap typically lives
Illustrative pattern. Pixel / CAPI accuracy is consistently the largest single cause across recent Meta reads.
What you receive
Each of the 5 layers scored Green / Amber / Red with one-line rationale.
The three most material structural issues, ranked by recoverable revenue and effort to fix.
What to fix first, second, third. Sequence matters; CAPI fixes often invalidate later checks.
Whether the work fits the agency, the in-house team, or the paid Conversion Second Opinion.
A live call to walk findings, on request. Not required to receive value from the written read.
The audit ends with the deliverable. No proposal, no upsell push, no commitment implied.
The position
More creative on a broken Pixel produces more noise, not more results. The audit names the signal layer that the rest of the work compounds on.

Stan’s take
The most common failure mode in Meta accounts is silent: Pixel and CAPI are both deployed, but the dedup key is wrong, AEM priorities are misordered, or iOS conversions never reach the algorithm. The account looks fine for months. The optimiser is making decisions on incomplete data. The cost shows up as creative testing that does not compound, audience strategy that does not stabilise, and ROAS that drifts down without an obvious cause.
The audit's job is to read the signal layer before the creative layer. Sometimes the finding is "your Pixel needs one parameter changed." Sometimes it is "your dedup key has been broken for nine months." Sometimes it is "Meta is not the platform; the buyer for this product is not here." Each of those is a different next step, and the audit names which one.
