12 Signs Your Google Ads Account Needs an Audit

Why these signs matter more than a gut feeling

Most business owners know something’s off with their Google Ads before they can say exactly what. Cost per lead has crept up, someone mentions a competitor is everywhere, or a monthly report lands that’s technically accurate but doesn’t actually explain anything. That vague unease is worth listening to — but it’s not diagnostic on its own.

The signs below are the concrete, observable things I look for when I sit down with an account for the first time. None of them individually proves the account is being mismanaged — every account has quirks. But when two or three of these show up together, that’s usually when I tell a business it’s worth getting a proper look, rather than waiting another quarter to see if things improve on their own.

The twelve signs

Cost per acquisition is rising and nobody can explain why — a CPA trend line going the wrong way is normal occasionally; a CPA trend line going the wrong way for months with no accompanying explanation (market change, seasonality, a tracking fix) usually means nobody’s actually looking at the account closely enough to notice.
A large share of spend sits in Display or Performance Max with no visibility into where it’s going — PMax and Display can genuinely add value, but if a third or more of your budget is in a campaign type where nobody can tell you which placements, audiences or search categories are actually spending the money, that’s a control gap, not a strategy.
There’s no negative keyword list, or it hasn’t been touched in months — negative keywords are one of the simplest, cheapest levers in the entire account and the first thing I check. An account with an empty or stale negative list is almost always leaking spend on searches that were never going to convert.
Conversion actions don’t match real business outcomes — the account might be optimising beautifully towards a goal that isn’t actually your goal: counting a form submission as a conversion when half of those never become a real enquiry, or tracking a phone number click rather than an answered, qualified call. Smart Bidding will hit that target with total precision — it’s just the wrong target.
The account structure was inherited from a previous agency and never rebuilt — campaigns, ad group names and naming conventions that clearly belonged to someone else’s process, still sitting there untouched months or years after you switched, are a strong sign nobody’s actually rethought the account for your business as it is now.
Nobody can tell you the target CPA or ROAS, or why it was set where it is — Smart Bidding needs a target to aim at. If that number was set once, a long time ago, and nobody currently working on the account can explain the logic behind it today, it’s probably stale relative to your current margins and average order value.
You’ve never seen a search terms report — the search terms report is where you find out what people actually typed before your ad showed. If you’ve never been shown one, or don’t know it exists, there’s a good chance irrelevant traffic has been quietly funded for a long time.
The same ads have been running unchanged for a year or more — ad copy does go stale, and Google’s own per-asset performance data — which replaced the old Low/Good/Best labels with full stats per headline and description in 2025 — is there for a reason. Untouched ads for twelve months plus usually means nobody’s testing, which usually means nobody’s trying to improve the account, just maintain it.
Budget is spread thinly across too many campaigns — Smart Bidding needs a reasonable volume of conversions per campaign to learn properly. An account with a dozen campaigns each getting a handful of conversions a month is starving every one of them of the data it needs to bid well.
Conversion tracking hasn’t been checked since the day it was set up — tracking breaks quietly. A site migration, a cookie consent tool, a form plugin update — any of these can silently stop conversions recording weeks before anyone notices the numbers look thin.
Reporting only covers impressions, clicks and cost — those are activity metrics, not outcome metrics. If a report never mentions cost per lead, cost per sale, or how those figures moved against the previous period, it’s describing effort, not results.
You don’t actually know how your PPC person or agency is paid — a flat management fee, a percentage of spend, and a media markup baked into the cost of clicks all create very different incentives. If you can’t say which one applies to your account, it’s worth finding out before assuming the incentives are aligned with your growth.

Being honest about this

Not every account with one or two of these signs needs urgent surgery. Small accounts with modest budgets often can’t support twelve pristine campaigns and a fully populated negative list — that’s a reasonable trade-off given the spend involved. I’ve audited accounts that turned out to be in decent shape and told the client to stay put. The point of an audit is to find out which situation you’re actually in, not to manufacture a reason to change something that’s working.

What a proper audit actually checks

Conversion tracking integrityWhether the conversion actions Google Ads is bidding towards match real, qualified business outcomes, and whether the tracking itself is firing accurately and once per genuine action.
Account structure and historyHow campaigns, ad groups and settings got to their current state, and whether that structure still fits the business or is a legacy of how a previous team worked.
Search terms and negative keyword coverageWhat’s actually triggering your ads, how much of that spend is relevant, and how well-maintained the negative keyword infrastructure is across campaigns.
Budget allocation and bidding strategyWhether budget is concentrated enough for Smart Bidding to learn properly, and whether targets (CPA, ROAS, tCPA) reflect current margins rather than historical guesswork.
Reporting and transparencyWhether what’s being reported actually reflects business outcomes, and whether the fee structure and incentives behind the account are clear.

What to do if you recognise several of these

If you’ve read this and recognised three, four, five of these signs in your own account, the honest next step is a proper independent look — not another internal glance at the same dashboard by the same person who set it up. An audit is a fixed, one-off diagnostic: I go through the account, tell you plainly what I find — including if the answer is that it’s actually fine — and hand you a clear list of what needs fixing and in what order.

If you’d rather not wait for a formal audit, the fastest self-check is simply asking whoever runs your account to explain, in plain terms, your current CPA target, your negative keyword list, and what’s actually driving your PMax spend. If those answers come quickly and make sense, you’re probably in reasonable hands. If they don’t, that’s usually all the confirmation you need.

Frequently asked questions

How often should a Google Ads account be audited?

There’s no fixed rule, but a sensible baseline is once a year for a stable account, or immediately if you notice several of the signs above, if performance has changed sharply, or if you’ve just taken over an account from a previous agency or freelancer.

Will an audit disrupt my current campaigns?

No. An audit is a read-only diagnostic — I review the account, its settings, tracking and history without making changes. Any fixes identified are then yours to action, whether that’s with your current person, a new one, or by working with me going forward.

What if the audit finds my account is actually fine?

Then I tell you that. Being upfront is central to how I work — I only take on work where I can genuinely add value, and sometimes the honest finding is that your current setup is sound and you should stay where you are.

Can I audit my own account without hiring anyone?

Partially. You can check for an empty negative keyword list, ask what your conversion actions actually measure, and look at how long your ads have been running unchanged. What’s harder to self-diagnose is whether your conversion tracking is accurate and whether your account structure and bidding targets are genuinely suited to your business — that usually needs an independent, experienced set of eyes.

Does a bad audit mean my previous agency was incompetent?

Not necessarily. Accounts drift for all sorts of reasons — staff changes, business pivots, tracking that broke silently, or simply time. An audit is about establishing where the account stands today and what to fix, not assigning blame for how it got there.

How much does a Google Ads audit cost?

It depends on account size and complexity, so I don’t quote a fixed figure without seeing the account first. Get in touch and I’ll give you a straight answer on scope and cost for your specific setup.
