PPC audit.
Where the budget bleeds, and which fix it is.
Updated May 2026 · AI-search reviewed · 72-hour written diagnostic
A paid media account that under-performs is not one big problem. It is one of five structural layers failing while the other four still report green metrics. This door names the five, walks the diagnostic, and routes you to the page that fits the spend, the platform, and the situation.

The budget bleeds here
One layer.Five layers run a paid media account. Four can be working while one bleeds 30 to 60 percent of the spend. The diagnostic question is which one.
Short answer
A PPC audit is a structured diagnostic of paid advertising accounts. It names where the spend is being lost, why, and the fix sequence. Five structural layers fail one at a time: account architecture and goal coherence, audience signal architecture, creative and offer-message alignment, conversion tracking and attribution accuracy, and placement and search-term waste. Stan Consulting delivers the audit as a 72-hour written read after read-only account access is granted. The report ranks fixes by revenue impact, then routes the engagement to either an in-house fix, a Revenue Sprint execution, or no follow-on. The audit is the product, not the pitch. No retainer is implied.

Why this keeps recurring
Four reasons a PPC waste problem stays hidden.
The agency owns the layer.
The layer that is bleeding budget is often the layer the agency manages. The agency cannot honestly diagnose it.
PMax hides its placement mix.
Performance Max suppresses placement detail. The waste lives in Display while the report frames it as Shopping.
Conversion events fire twice.
Pixel plus CAPI plus enhanced conversions duplicate events. The dashboard inflates; the bank does not.
The pattern in one diagram
Budget enters at the top. One layer eats it.
Illustrative. The actual leaking layer is named by the audit, not by the diagram. The diagram’s point: spend exits layered, not flat.
FThe framework
The Five-Layer Paid Media Diagnostic.
Five structural layers. One is bleeding budget. The diagnostic identifies which one, and which fix sequence the operator should follow. The order matters. Optimising bids on a campaign whose conversion tracking is broken just produces faster wrong answers.
01
Account architecture and goal coherence.
Whether the campaign structure, naming, conversion goals, and budget allocation match the business model the account is supposed to serve. Most underperforming accounts have a structure that made sense two years ago and was never updated when the offer, the prices, or the buyer journey changed. The first audit question is not "is the bid right" but "is the structure right."
Diagnostic tellsConversion goals counting page views as sales, campaigns named after the consultant who launched them, brand and non-brand mixed in one campaign, budget split that does not match the margin of the products inside, PMax running on top of Search without exclusion.
02
Audience signal architecture.
What the platform has been told to find. Keywords, audience segments, custom audiences, lookalikes, broad signals. The audience signal is the platform's instruction set. Bad signals produce expensive impressions even when bidding is perfect. Common gaps: broad-match drift after Google's match-type changes, audience overlap on Meta that bids against itself, lookalikes built on the wrong source audience.
Diagnostic tellsSearch terms report full of unrelated queries, Meta audience overlap above 30 percent across active adsets, lookalikes built on All Customers instead of LTV-top quintile, custom audiences older than 180 days never refreshed, no exclusion of existing customers on prospecting campaigns.
03
Creative and offer-message alignment.
Whether the ad creative and copy match the offer the landing page makes, in the language the buyer uses. Creative-message gaps are the most common cause of high cost per click and low conversion rate simultaneously. The ad over-promises, the landing page under-delivers, the click is real and the conversion is not. Creative fatigue is real; offer-page mismatch is bigger.
Diagnostic tellsAd creative naming the discount the landing page does not show, hero image on ad different from hero image on page, headline promise that the page first paragraph cannot match, CTR above 2 percent with conversion rate below 1 percent, frequency above 4 with falling ROAS.
04
Conversion tracking and attribution accuracy.
Whether the conversion events the platform fires reflect actual revenue events, with no duplication or undercounting. The fourth layer is the one operators discover last. The dashboard shows green and the bank account shows flat. Half of "PPC is not working" cases are actually "PPC tracking is not working" cases. Pixel and CAPI duplication, GA4 and Google Ads conversion counts diverging, server-side tracking pointing at the wrong conversion event.
Diagnostic tellsGA4 conversion count differing from Google Ads by more than 15 percent, Meta Pixel firing on both view and purchase events without dedup, server-side conversions firing twice on the same order, attribution model never documented, brand-search campaign claiming credit for direct buyers.
05
Placement and search-term waste.
Where the spend actually went, vs where the operator believes it went. Search terms drift, automatic placements pull spend into garbage sites, PMax shoves the budget into Display when Shopping was the goal, broad match expands into unrelated queries. The waste audit asks one question: what is the largest line item nobody approved?
Diagnostic tellsSearch terms report showing 30 percent or more spend on non-converting queries, PMax placement data showing Display dominating Shopping, mobile-app placements pulling budget on Display, Meta auto-placements running on Audience Network with no exclusion, no negative keyword list maintained in the last 90 days.
The inflection
Bidding is activity.
Structure is strategy.
Stan Consulting · structural observation across PPC reads
Bidding harder on a campaign whose conversion tracking is broken just produces faster wrong answers. The structure decides what the bid can do.Pattern observation · Stan Consulting
Three priorities before any bid change
01
Name the layer that is bleeding the budget.
02
Verify conversion tracking before trusting ROAS.
03
Remove waste first. Optimisation lifts a clean account, not a leaking one.
The decision question
Diagnose before you bid.
Every layer has a different fix. Bid adjustments solve nothing if the conversion event is wrong, the audience signal is broad, or PMax is shovelling spend into Display. The audit identifies the layer; the fix follows.
Choosing the right tool
Paid audit vs management retainer vs free vendor audit vs platform recommendations.
| Dimension | Conversion Second Opinion | PPC management retainer | Free vendor audit | Platform recommendations |
|---|---|---|---|---|
| What it produces | Written diagnostic ranking the layer bleeding budget and the fix sequence. | Monthly execution and reporting. Sometimes a quarterly review. | A sales deck framed as an audit. Ends with a proposal. | Automated suggestions inside the ad platform. Mostly toward more spend. |
| Incentive alignment | Paid for the deliverable. No follow-on commitment, so the findings can be honest. | Paid to manage. Incentive to keep the scope. | Paid only if the operator signs the retainer. | The platform earns more when you spend more. |
| Fee structure | $999 one-time. Larger spends scoped after intake. | Monthly. Percent of spend or flat fee. Usually 6-month minimum. | Free at the audit stage; expensive after. | Free. Acted on by the operator or the agency. |
| Time to first deliverable | 72 hours after read-only access is granted. | 2 to 4 weeks for first material changes. | 3 to 10 business days. Often a templated deck. | Immediate. Quality varies. |
| Best when | Operator wants to know which layer is failing before committing to a rebuild, a retainer, or a switch. | The layer is named and execution capacity is the constraint. | Operator is shopping vendors and wants a first read at zero cost. Useful only to triangulate; not actionable on its own. | Account is healthy; small optimisations are the goal. |
| Worst when | The structural problem is at the offer or pricing level, below the ad layer. | The structural problem is the layer the agency owns. | Operator needs honest findings. Free audits cannot deliver them by design. | The structural problem requires removing spend, not adding it. |

The position
Fix the layer.
Not the bid.
Bid adjustments compress symptoms. They do not touch placement waste, broken tracking, or PMax cannibalisation. The audit names the layer that bid changes cannot reach.

FAQ
Eight questions operators ask before booking a paid audit. Answered in principal voice, not sales voice.
What is a PPC audit?
A structured diagnostic of a paid advertising account that names where the budget is being lost, why, and the fix sequence. It covers account architecture, audience signal, creative-offer fit, conversion tracking, and placement waste. The audit produces a written deliverable, not a sales pitch.
Read: Paid Advertising Management service →How is a PPC audit different from free vendor audits?
Free vendor audits are sales motions. They surface enough to start a conversation and stop short of what the operator needs to act independently. A paid audit with a written deliverable and no retainer attached is structurally able to tell the truth because there is no downstream incentive to soften findings.
Read: agencies sell activity when they cannot sell judgment →How long does a PPC audit take?
Stan Consulting's diagnostic format is a 72-hour written read after read-only account access is granted. Multi-platform accounts (Google plus Meta) can run 96 to 120 hours depending on spend size and account complexity.
Read: Conversion Second Opinion →What does a PPC audit cost?
The Conversion Second Opinion entry is $999 for a single-account read. Larger accounts (over $50K monthly spend or multi-platform) are scoped after intake. There is no retainer attached to the audit; it is the deliverable, not the pitch.
Read: CSO pricing →Should I do a PPC audit on a new account or wait?
Below 90 days of spend, the data is too thin for structural diagnosis. The exception is when the operator suspects the account is set up wrong from the beginning (broken conversion tracking, wrong campaign type, missing brand exclusion). For new accounts an audit of the setup decisions is useful; an audit of performance data is not.
Read: Google Ads 23-point review →What is the difference between a Google Ads audit and a Meta Ads audit?
The structural layers are the same; the specific failure modes differ. Google Ads audits focus on search-terms drift, brand cannibalization, match-type behavior, and PMax asset-group structure. Meta Ads audits focus on Pixel and CAPI event accuracy, audience overlap, creative-fatigue cycles, and iOS attribution gaps.
Read: Meta Ads audit →Should my agency have admin access to my ad accounts?
No. Agencies should have user-level access; admin access should sit with the account owner. Admin-level access by the agency creates lock-in risk, prevents independent audits, and makes attribution disputes harder to resolve.
Read: ad account access reference →What does a Stan Consulting PPC audit include?

Stan’s take
PPC audits should produce decisions, not proposals.
The category is choked with free audits that surface enough to start a sales conversation and stop short of what the operator needs to act independently. The structural reason is simple: a free audit's purpose is to win the retainer. Once that is true, the findings get softened wherever they would point to the wrong-shaped engagement.
A paid audit with a written deliverable and no retainer attached is structurally able to tell the truth. The audit names which layer is wasting spend. The fix order is the buyer's, not the auditor's. Sometimes the right answer is "change one conversion event and walk away." Sometimes it is "consolidate three vendors into one." It is never "we recommend a twelve-month engagement at twelve thousand per month."
The Conversion Second Opinion exists to produce that decision in 72 hours, in writing, with the platform-specific layer named.

If this is your situation
Route to the right next step. Not every account is a Conversion Second Opinion.
Monthly spend $10K to $500K, accounts open more than 90 days, reports look fine, revenue does not match. The five-layer diagnostic fits.
Conversion Second Opinion →Account is under 90 days old and you suspect the setup decisions were wrong (campaign type, tracking, brand exclusion). A setup audit, not a performance audit.
Setup audit →Diagnostic is already done and you need execution. 30-day fixed-scope, no retainer.
Revenue Sprint →You want ongoing management after the diagnostic, not a one-time fix.
Paid Advertising Management →You want a free first look before committing to a paid audit. Useful for triangulation, not for action.
