Why most Google Ads audits miss the real issue.

We have run more than two hundred Google Ads audits in the last few years. Every one is different — different vertical, different scale, different team behind it. But after the hundredth or so, patterns become impossible to ignore. The interesting problems in most accounts are never the things people think they need an audit for.

When prospects book audits with us, they almost always frame the question as a tactical one. "Our CPCs are creeping up." "Our ROAS is plateaued." "Our PMax is underperforming." These framings are reasonable but rarely correct. The real issue is almost always upstream of where they are looking.

Three structural issues appear in roughly 80% of accounts we audit. Each one undermines every other optimization effort until it is fixed. None of them have anything to do with bid strategy, keyword choice, or ad copy.

Issue one: brand and non-brand traffic mixed in the same campaigns

When you bid on your own brand name and somebody searches it, they were probably going to find you anyway. They typed your brand into the search bar. They might have come from organic, an email, an Instagram ad, or just remembering you. Counting those conversions as paid acquisition revenue is a measurement error — but most accounts make it routinely.

The accounting sin compounds. Smart Bidding optimizes toward conversion volume. Brand searches convert at extremely high rates because of intent. So the algorithm decides to spend more on brand keywords. Reported ROAS goes up. Real incremental revenue does not change. The CFO is confused about why margin keeps shrinking despite "improving" ad performance.

Issue two: conversion definitions that have not been audited in years

Most accounts have conversion actions configured years ago by someone who is no longer at the company. Half of them are misconfigured. Counts that include duplicates from confirmation page reloads. Lead form fills counted alongside completed checkouts. Engagement events being treated as conversions. We open the conversion settings and find six active conversion actions, four of which contradict each other.

This matters because Smart Bidding optimizes toward whatever you tell it to. If your conversion definition is wrong, every bidding decision in the account is optimizing toward the wrong outcome. Fix the conversion definition and reported performance often gets worse — but real performance gets better, because the optimization finally points at something true.

The fix is straightforward but tedious. Audit every conversion action. Define exactly what counts. Document the definition. Then check it monthly. Almost no agencies do this work because it is boring and not glamorous, but it determines everything downstream.

Issue three: the 30% of spend that nobody can explain

In nearly every account we audit, somewhere between 20-40% of monthly spend cannot be reasonably defended. Old display campaigns left running. Geographic targeting that includes regions the brand does not ship to. Audiences that overlap so heavily they cannibalise. Search terms attracting clicks that obviously will never convert. Negative keyword lists that have not been touched in eighteen months.

This waste is hard to see because the dashboard reports the account as profitable. The waste sits inside accounts that are still beating their ROAS target on average. Cut the waste and the same revenue is achievable on 30% less spend — or the freed budget produces incremental revenue when redirected to working campaigns.

The pattern is consistent enough that we now factor it into how we scope new engagements. The first 90 days of work for any account are foundation cleanup, not tactical optimization. The interesting work — bid strategy, creative testing, audience expansion — only compounds after the foundations are right.

Why this matters more than tactics

Tactical advice — "use broad match for these keywords", "increase your tROAS by 10%", "test responsive search ads with these headlines" — is everywhere on the internet. It is also mostly useless if your foundations are wrong. The same tactical move applied to a clean account compounds. Applied to an account with broken conversion tracking and brand cannibalisation, it just shifts the noise around.

The unglamorous truth of paid media is that 70% of the work that matters is foundational. Account architecture, conversion definition, attribution setup, audience strategy, exclusion logic. The remaining 30% is tactical execution. Most agencies invert that ratio and wonder why their work doesn't compound.

If you have not had a serious foundational audit on your account in the last twelve months, you almost certainly have one of these three issues. Probably more than one. Run our free audit, or run someone else's. Just do it.
