When a Google Ads campaign looks fine on the surface but refuses to deliver results, it is almost always because something crucial is being missed under the bonnet.

A proper audit is not about adding endless new ideas into the mix. It is about finding and fixing the hidden problems already slowing you down. Over the years running campaigns for clients across countless industries, I have learnt that the best audits stay simple, strategic, and sharply focused.

This is the exact step-by-step process we work through when we audit an account. It moves from the foundations (goals and structure) out to the newer, automation-heavy areas (Performance Max, Smart Bidding, and consent-driven tracking) that decide whether a modern account performs or quietly leaks money.

The 12-point Google Ads audit checklist

If you want the short version, here is the whole audit as a tickable checklist. Each row is expanded further down the page.

Now, the detail behind each area.

1. Start with the campaign goals

Before diving into the finer details, step back and ask yourself: what is this campaign actually trying to achieve?

It is frighteningly common to see campaigns set to optimise for clicks or impressions, rather than real conversions. If you are not targeting meaningful actions – like purchases, leads, or sign-ups – you are essentially paying for noise.

Always make sure your campaign objectives align with business goals. If not, no amount of tweaking will save it.

2. Sanity-check the account structure

Before you audit the moving parts, look at how the account is put together. Are campaigns split in a way that reflects intent, margin, and budget priority? Or have three overlapping campaigns ended up bidding against each other on the same queries?

Structure is not about a “correct” number of campaigns. It is about making sure spend flows where it should and that each campaign has a clear job. When two campaigns compete for the same searches, you pay more for the privilege. We wrote separately about why we sometimes run two search campaigns rather than one – but the principle either way is deliberate structure, not accidental sprawl.

3. Revisit your keyword match types

Keyword match types control who sees your ads. Rely too heavily on broad match, and you risk burning through budget on irrelevant searches that were never going to convert.

A healthy account usually has a smart mix of match types – broad match to widen reach (but only with strong audience signals and Smart Bidding underneath it), phrase match to stay relevant, and exact match to lock onto the high-intent searches you really want.

Broad match has its place, but it needs to be handled with precision. In practice, broad match and automated bidding are now inseparable: broad match without a well-fed Smart Bidding strategy steering it is where budgets disappear fastest. We audit the two together (see step 11).

4. Dig into the search terms report

One of the most underused tools in Google Ads is the Search Terms Report. It shows you exactly what people typed into Google before clicking your ad – and it is often eye-opening.

If you see irrelevant queries slipping through, add them as negative keywords. Doing this regularly sharpens your targeting and stops you wasting budget. A shared negative keyword list applied across campaigns saves you repeating the same work account-wide.

The goal is simple: only pay for traffic that has a genuine chance of converting.

5. Review ad relevance and copy

There is no excuse for guesswork when it comes to your ad copy. If your ads are not tightly aligned with the keywords and the landing page, performance will always suffer.

Think of it this way: if someone searches for “affordable wedding photography London”, they do not want to land on a generic page about “event photography services”. They want to feel like they have found exactly what they were looking for.

Consistency between search intent, ad copy, and landing page messaging is one of the biggest levers you can pull to boost results.

6. Evaluate the landing page experience

Getting the click is only half the battle. What happens after that is just as important.

If your landing page loads slowly, looks confusing, or buries the offer under a mountain of waffle, people will leave – fast.

A good landing page should load quickly, deliver a crystal-clear offer above the fold, and make it ridiculously easy for visitors to take the next step.

You have paid for the click – do not waste it.

7. Analyse device and location performance

Not all devices and locations perform equally. In fact, it is rare that they do.

Always dig into your data by device type and geography. You may find mobile traffic bouncing while desktop users convert beautifully. Or that certain regions chew through your budget without delivering results.

Rather than treating every click as equal, be ruthless. Pause or down-bid where performance is poor, and redirect spend towards where it is making a difference.

PPC success is often about focusing firepower where it matters most.

8. Check your conversion tracking

Without solid conversion tracking, you are flying blind.

It is not enough to simply have tracking “set up”. You need to be sure it is firing correctly, recording real actions, and matching your business objectives. Use Google Tag Assistant to confirm your conversion tags actually fire on the right pages and that the values passed are sensible.

If tracking is broken or missing, your optimisations will be based on false data. It is one of the first things we audit for every new client – because without it, you are guessing, not strategising.

This is where a lot of UK accounts are quietly broken. For traffic from the UK and the European Economic Area, Google requires Consent Mode v2 to be in place before your account can build remarketing audiences, model missing conversions, or use Enhanced Conversions. Consent Mode v2 passes two signals to Google – ad_storage and ad_user_data – based on the choices a visitor makes in your cookie banner.

The practical audit checks are:

  • Is Consent Mode v2 actually implemented? Without it, you lose access to audience building, conversion modelling, and Enhanced Conversions for UK/EEA traffic, and your reported conversions can drop noticeably.
  • Are Enhanced Conversions turned on and gated correctly? Enhanced Conversions send hashed first-party data (like an email address) to Google to recover attribution that cookies alone would miss. They are governed by the ad_user_data signal – when consent is granted, hashed data can be sent; when it is denied, Enhanced Conversions are blocked. That is the intended, compliant behaviour.
  • Does the consent banner map to the right signals? A banner that never grants ad_user_data will suppress data you are legitimately allowed to collect, while one that ignores consent entirely is a compliance problem.

If Consent Mode v2 and Enhanced Conversions are not set up properly, every downstream optimisation – bidding included – is working from incomplete data. For the wider tracking picture, we also cover how to track LLM referral traffic in GA4.

10. Audit Smart Bidding, budget and pacing

In 2026 you cannot audit match types without auditing the automated bidding sitting underneath them. When an account runs Target CPA or Target ROAS, the targets themselves are a common failure point.

  • Are the targets realistic? A Target CPA set far below what the account has ever actually achieved will throttle delivery; a target set too loosely lets spend run away. Compare the target to genuine historical performance before judging the strategy.
  • Have you accounted for conversion delay? If your typical conversion takes days to complete, the last few days of data are always understated. Exclude the most recent conversion-delay window before you conclude a strategy is failing.
  • Are seasonality adjustments being used correctly? These are a manual override for short, predictable events – a weekend sale, a launch, a holiday promotion – not a permanent lever. Misused, they distort bidding.
  • Is the campaign limited by budget? Check Search lost impression share (budget). If you are losing impressions to budget, your best-converting campaigns may simply be running out of money each day.

One naming note for anyone auditing an account through the interface: Google renamed the target-based strategies so that “Maximize conversions with a Target CPA” is now shown as Target CPA, and “Maximize conversion value with a Target ROAS” is now Target ROAS. The underlying behaviour is unchanged – only the label differs, so do not be thrown if the account and older guides use different wording.

11. Audit your Performance Max campaigns

Performance Max is usually the biggest single blind spot in an audit, because so much of it is automated and hidden. It is also where a “looks fine” account most often leaks money. Work through these checks:

  • Channel spend split. Performance Max now surfaces channel-level reporting, so you can see roughly how spend is dividing across Search, Shopping, Display, YouTube and the rest. If a lead-gen account is pouring budget into Display placements that never convert, you will spot it here.
  • Brand exclusions. By default, Performance Max can serve on your own brand terms and take credit for traffic you would have won anyway. Apply brand exclusions so PMax is measured on incremental, non-brand demand rather than flattering itself with brand searches.
  • Negative keywords. Performance Max now supports campaign-level negative keywords on a self-serve basis, and Google has raised the limit well beyond the old cap of 100. Use them to keep PMax off irrelevant or wasteful queries, just as you would on a Search campaign.
  • Search terms report. Performance Max has a campaign-level search terms report. Review it the same way you review Search: find off-intent queries and exclude them.
  • Asset group performance. Check each asset group’s assets and reporting. Weak or “Low” rated assets drag performance; refresh headlines, descriptions, images and video rather than leaving thin asset groups running.

If you are weighing PMax against other automated options, our guide on Performance Max vs Demand Gen is a useful companion, and we have a separate piece on why running PMax without a Shopping feed leaves money on the table.

How often should you audit – and what should trigger one?

A full audit belongs on a schedule – quarterly is a sensible baseline for most accounts, with a lighter monthly review of search terms, negatives and pacing in between. But some warning signs should trigger an audit straight away, whatever the calendar says:

  • Rising cost per acquisition (CPA) with no matching lift in conversion value.
  • Falling impression share, especially a jump in lost impression share to budget or to rank.
  • A sudden drop in Optimisation Score, or a batch of recommendations that suggests Google thinks something is off.
  • Conversion volume that falls off a cliff – frequently a broken tag or a consent misconfiguration rather than a real drop in demand.

Treat these as smoke. The audit is how you find the fire.

A quick before-and-after

To make it concrete: on one lead-generation account we took over, reported conversions had quietly collapsed after a website replatform. The audit found a single broken conversion tag that had stopped firing – Smart Bidding was optimising against almost no data. Repairing the tag restored conversion tracking, and with the bidding strategy finally fed real data again, cost per lead came back down over the following weeks. Nothing exotic; just the basics, checked properly.

Final comments

A proper Google Ads audit is not about overwhelming yourself with endless new tactics. It is about sharpening the basics and finding where your current efforts are leaking money or missing opportunities.

Get the foundations right – campaign goals, structure, keywords, ad relevance, landing pages, targeting, and tracking – then add the modern layers of Consent Mode v2, Smart Bidding and Performance Max, and your results will often lift dramatically without needing to spend a penny more.

Frequently asked questions

How long does a Google Ads audit take? A focused audit of a single account can be worked through in a few hours if you follow a checklist like the one above. Larger accounts with multiple campaign types, Performance Max, and Shopping feeds take longer, mainly because there are more areas to review and cross-check.

How often should I audit my Google Ads account? A full audit each quarter is a good baseline, with lighter monthly reviews of search terms, negative keywords and budget pacing in between. Audit sooner if you see red-flag metrics such as a rising CPA, falling impression share, or a sudden drop in conversions.

Do I need Consent Mode v2 in the UK? If you serve ads to users in the UK or the European Economic Area and want to use remarketing, audience building, conversion modelling or Enhanced Conversions, Consent Mode v2 is effectively a requirement. Without it, Google restricts these features and your measured conversions can drop.

What is the difference between Target CPA and “Maximize conversions with a Target CPA”? They are the same strategy. Google renamed the target-based bid strategies, so “Maximize conversions with a Target CPA” now appears simply as “Target CPA” (and the value equivalent as “Target ROAS”). The bidding behaviour did not change – only the label.

Can I see search terms in Performance Max? Yes. Performance Max has a campaign-level search terms report, so you can review the actual queries triggering your ads and add negatives for anything off-intent, much like you would on a standard Search campaign.
