The paid media audit: how to find the money leaking out of your ad account

Every ad account leaks. The questions are how much, where, and which leaks are worth fixing. A paid media audit exists to answer those three with numbers, not opinions.

There is already a checklist-style version of this on my blog: Paid media audit: what to check before you increase ad spend. This post is different. It is about method: how you trace money from the ad platform to revenue, how you put a value on each leak and how you decide which ones to fix first. A checklist tells you where to look. A method tells you what it is worth.

What counts as a leak

A leak is spend that does not produce a qualified outcome, or an outcome you have counted wrongly. That second part matters. Some of the biggest leaks are not wasted clicks. They are conversions reported twice, leads that never reach sales and brand searches taking credit for demand you already had.

If you define a leak only as wasted clicks, you will fix the small ones and miss the large ones.

Step 1: Build one table from spend to revenue

Start with a single sheet. One row per campaign. Columns from left to right: spend, clicks, platform conversions, leads recorded in your CRM, qualified leads, opportunities, pipeline and closed revenue.

The right-hand columns take effort. You need a CRM export with source and campaign fields, and your UTMs have to be reliable. If they are not, that is your first finding, and a serious one: if you cannot connect spend to outcomes, you cannot know what is leaking.

For ecommerce, replace the lead columns with orders, revenue and margin.

Step 2: Find where the numbers stop agreeing

Read the table from left to right and look for the first big drop or mismatch.

If the platform reports far more conversions than the CRM holds leads, something is being counted twice or counted too loosely. If leads are plentiful but few are qualified, the problem is targeting, the offer or the form. If qualified leads are healthy but opportunities are thin, look at speed to contact and routing inside sales. If pipeline is fine but revenue is not, the ad account may not be the problem at all.

The first place the numbers disagree tells you which part of the system to inspect first. It stops an audit from turning into a tour of every setting in the account.

Step 3: Check the six places money usually leaks

Once you know the stage, look at the usual suspects.

Search queries and placements. Read the search terms report and, for display or video, the placements. Look for irrelevant queries, job seekers, students and people hunting for free tools.

Brand traffic taking credit. Branded search often converts well and looks efficient. Separate it from non-brand, then ask how many of those people would have found you anyway.

Conversion tracking. Look for duplicate tags, conversions firing on page loads, small actions counted as primary goals and optimisation toward form fills rather than qualified leads.

Segments that never convert. Break spend down by location, device, time of day and audience. Some segments take real budget and return nothing.

Overlap and fatigue. Check whether campaigns bid against each other, whether audiences overlap and how often the same people see the same ad.

The page after the click. Slow pages, long forms, mismatched promises and slow follow-up leak money after the ad has done its job.

You will not find all six in every account. You will usually find two or three.

Sometimes the audit points away from the ad account, to slow replies, a pricing page that contradicts the ad or lead routing that sends enquiries to the wrong person. These are still leaks. Include them and name an owner outside marketing, because blaming the ads for something the ads did not do is the fastest way to lose trust in an audit.

Step 4: Put a number on each leak

A finding without a value gets ignored. For each leak, estimate the monthly cost in simple terms.

For a wasted segment: the monthly spend on that segment, minus the spend you would accept given what it produces. For double-counted conversions: the spend you credited to a channel on the strength of conversions that were not real. For post-click losses: the number of qualified leads lost, multiplied by what a qualified lead is worth to you.

These are estimates, and I label them that way. The goal is to rank the leaks, not to produce a precise figure. If one leak is ten times the size of another, you do not need decimals to know where to start.

Step 5: Fix the biggest three, not the longest list

An audit that returns forty recommendations produces no action. After sizing the leaks, rank them on two things: value and effort. A negative keyword list takes an afternoon. Rebuilding tracking takes longer but may be worth far more.

I aim for three priorities for the first 30 days, each with an owner and a date. Everything else goes on a later list. Leaks you do not fix this month will still be there next month, and you will have the sizing to come back to.

Be careful not to fix the visible small leaks first just because they are easy. That feels productive and leaves the large problem in place.

Step 6: Measure again after 30 days

An audit is complete when you can show the effect of the fixes. Return to the same table after a month. Did the gap between platform conversions and CRM leads close? Did spend move away from segments that never converted? Did qualified leads per unit of spend improve?

Some fixes will not show up straight away, particularly where sales cycles are long. Say so in advance, and decide which early signals you will accept in the meantime.

Do not judge an account on a week of data after a change. Automated bidding often needs time to adjust.

What a good audit hands back

• The spend-to-revenue table, so you can see the logic

• A ranked list of leaks with estimated values

• The three priority fixes, with owners and dates

• A tracking review, written in plain language

• A short list of things that are working, so no one breaks them

If you receive a long slide deck with no values attached, you have received an opinion, not an audit.

Where organic search comes in

Paid search shows you which queries bring buyers. When an audit finds you are paying for clicks on terms you could rank for, there may be a case for investing in organic content. I explain how I approach that on my SEO services page. For B2B software accounts specifically, my post on B2B SaaS paid acquisition shows how the pieces connect.

Start the spend-to-revenue table this week, even if the right-hand columns are blank. The blanks are a finding. If you would like a second pair of eyes, I run one-time campaign audits as part of my work. I am a solo senior operator supported by automation, and I take about four projects a quarter, so book a discovery call early and I will tell you what I would want to see first.

FAQ

What is a paid media audit?

A structured review that traces ad spend from the platform through leads, pipeline and revenue, to find where money is wasted or outcomes are miscounted, and ranks the fixes by value.

How often should I audit my ad account?

A full audit makes sense when performance stalls, before you raise spend or when you take over an account. Between audits, a weekly check on search terms and tracking catches drift early.

What do I need to run a paid media audit?

View access to the ad accounts, a CRM export with source and campaign fields, and reliable UTMs. Without the CRM data you can audit the ads but not what they produced.

Can a paid media audit show the ad account is fine?

Yes. Sometimes the leak sits in follow-up speed, the offer or the landing page. An honest audit says so and names where the problem is.
