A Google Ads audit isn’t a checklist you tick off. It’s finding the money your account is leaking, then fixing it in order of what pays back fastest.
A Google Ads audit is a structured review of an advertising account that checks whether every dollar is working: the right things tracked, the right searches targeted, the budget pointed at what converts. Most advertisers never run one. They tweak a bid here, pause a keyword there, and never step back to see the whole account at once, which is exactly how a profitable account quietly turns into a leaky one.
This is the complete, current framework we use to audit accounts every week, written out so you can run it yourself. It’s free, there’s no email gate, and it covers both the timeless fundamentals and the 2026 platform shifts most checklists still ignore. If you’d rather we run the audit for you, that’s what we do, but you’ll get further reading this than you will from any “free Google Ads audit” tool that hands you a score and a sales call.
- A Google Ads audit is a structured review that finds where an account is leaking money: mistracked conversions, wasted spend, weak structure, and underused automation.
- Audit in eight areas: account structure, conversion tracking, keywords and search terms, bidding and budget, ads and assets, Quality Score, targeting, and the 2026 automation layer (PMax, AI Max and signals).
- Most free Google Ads audits are lead-generation, not diagnostics. A real audit takes expert hours and judgement, not a one-click score.
- The 2026 layer most checklists miss: PMax brand exclusions, channel distribution, AI Max query drift, branded-versus-non-branded splits, and data-driven attribution.
- Australian realities change the maths: 10% GST distorts reported ROAS, a smaller market makes Smart Bidding's signal-density threshold harder to hit, and the location-targeting default quietly widens your reach.
- Prioritise findings by revenue impact, not audit-tool severity. Fix what recovers the most money first.
What is a Google Ads audit?
A Google Ads audit is a systematic review of an account’s structure, tracking, targeting and spend to find where performance is being lost and what to fix first. It answers one question: is this account turning budget into profitable customers as efficiently as it could be, and if not, where exactly is the leak?
A PPC audit means the same thing in practice. “PPC” (pay-per-click) is the broader category that covers Google Ads, Microsoft Ads and others, so a PPC audit and a Google Ads audit use the same method; this guide focuses on Google Ads because that’s where most Australian search budgets sit.
What an audit is not: it isn’t a one-click score from a tool, and it isn’t a list of 40 settings ticked off in isolation. A real Google Ads account audit reads the account as a connected system. A “good” Quality Score means nothing if conversions aren’t tracked properly; a tidy structure means nothing if the budget is starved. The value is in the judgement, not the checklist.
When (and how often) should you audit your account?
Some moments demand an audit before you do anything else. You’ve inherited an account, or a previous agency built it and you’ve no idea what’s underneath. Performance has plateaued or slipped and the usual tweaks aren’t moving it. You’re about to scale spend, and pouring more money into a leaky account just leaks faster. You’re going through an agency handover and want to know what you’re actually taking on.
Then there’s routine hygiene. We recommend a full audit quarterly for active accounts, with a lighter monthly check on tracking, search terms and budget pacing. Google changes the platform constantly, and an audit method that was right in 2023 can quietly mislead you in 2026.
The symptoms a good audit catches are the ones that don’t announce themselves: conversions double-counted so your reported cost-per-acquisition looks better than reality, a Performance Max campaign quietly eating your brand traffic and claiming the credit, a budget cap throttling your best campaign while a weak one spends freely. None of these show up as an error message. They show up as money you never see.
How to audit a Google Ads account: the framework
Work through eight areas in order, and for each one apply the same four-part rhythm: what to check, why it matters, what good looks like, and the red flag that tells you something’s wrong. That rhythm is what separates an audit from a settings checklist, because it forces a judgement at every step instead of a tick.
- Set your baseline. Pull 30 to 90 days of data and note the headline numbers (spend, conversions, cost-per-acquisition or ROAS) before you change anything.
- Verify the data first. Audit conversion tracking before anything else. If the numbers are wrong, every other judgement is built on sand.
- Work the eight areas in order. Structure, tracking, keywords and search terms, bidding and budget, ads and assets, Quality Score, targeting, then the 2026 automation layer.
- Log every finding with its money impact. Note what's wrong and a rough estimate of the spend it's wasting or the revenue it's costing.
- Prioritise by revenue, then act. Rank fixes by money recovered, not by how many issues sit in each area. Fix the biggest leaks first.
Here are the eight areas as a checklist you can copy and use as your own Google Ads audit template.
Account structure and settings
- Check: campaign-type separation, brand versus non-brand split, naming conventions, whether Search and Display are mixed in one campaign, ad rotation settings, and the location-targeting setting.
- Why it matters: structure decides where budget can flow and how cleanly you can read performance. Mixed campaigns hide which surface is actually working.
- What good looks like: brand and non-brand separated, Search and Display split apart, a consistent naming system, and location set to Presence (people in your target area) rather than the default.
- Red flag: location left on Presence or interest, the Australian default that also serves people merely searching about your area from anywhere in the world. It quietly inflates reach and waste.
Conversion tracking and data integrity
- Check: are you counting the right action, once; is Enhanced Conversions on; is Consent Mode set up; and for lead-gen, are qualified leads imported back via offline conversion import?
- Why it matters: this is where the most expensive mistakes hide. If tracking is wrong, Smart Bidding optimises towards the wrong thing and every report lies to you.
- What good looks like: one primary conversion that reflects real business value, deduplicated, with Enhanced Conversions live and lead quality fed back to Google.
- Red flag: every form view and page load counted as a conversion, or the same lead counted three times. Inflated counts make a failing account look healthy.
Keywords and search terms
- Check: match-type discipline, negative-keyword coverage, the actual search-terms report, and whether keywords compete with each other (cannibalisation).
- Why it matters: the search-terms report shows what people really typed. It's where you find the spend going to queries you'd never knowingly pay for.
- What good looks like: match types chosen on purpose, a maintained negative list, and search terms that read like genuine buyers, not noise.
- Red flag: in lead-gen, spend on job-seeker, DIY, support or competitor-research queries. These are the classic pollution patterns a search-terms review catches in minutes.
To audit the competitive side of your keywords, it helps to see what rivals are bidding on. Our guide to seeing your competitors’ Google Ads for free walks through the tools that surface their live ads and angles.
Bidding and budget
- Check: does the bid strategy fit the goal and the data volume; is it stuck in the learning phase; which campaigns are budget-limited; and what happens to cost-per-acquisition as you scale?
- Why it matters: Smart Bidding needs data to work. Below roughly 30 conversions a month, a campaign rarely has enough signal for Target CPA or Target ROAS to learn well.
- What good looks like: bid strategy matched to conversion volume, no critical campaign throttled by its budget, and a clear view of marginal cost at higher spend.
- Red flag: a high-value campaign flagged Limited by budget while a weaker one spends freely, or Smart Bidding running on a campaign with barely any conversions to learn from.
Ads and assets
- Check: responsive search ad strength, how thematically tight each ad group is, asset and extension coverage (sitelinks, callouts, images), and any disapprovals.
- Why it matters: assets lift Ad Rank at no extra cost per click, and tight ad groups keep ads relevant to the search, which improves both clicks and Quality Score.
- What good looks like: strong RSAs with varied headlines, a full set of relevant assets, and ad groups built around a single theme.
- Red flag: one generic ad per ad group, missing extensions, or disapproved ads sitting unnoticed and dragging delivery.
Quality Score: what it tells you (and what it doesn't)
- Check: Quality Score and its three diagnostic components, expected click-through rate, ad relevance, and landing page experience, at the keyword level.
- Why it matters: Quality Score is a diagnostic, not a target. A low component points you straight at the fix: the ad, the keyword match, or the page.
- What good looks like: components reading Above average, used to find weak spots rather than chased as a vanity number.
- Red flag: treating Quality Score as a goal in itself. It's a symptom dashboard; the cure lives in the ad and the landing page.
Quality Score is also a direct cost lever, because better ad quality lowers what you actually pay per click. We unpack that mechanism in how much Google Ads cost, and the competitive view of where you sit in the auction comes from auction insights.
Targeting: geo, schedule, device and audience
- Check: geographic targeting and bid adjustments, ad scheduling, device performance, and the quality of any audience signals you've added.
- Why it matters: targeting decides who sees the ad. Poor settings here waste budget on people who'll never buy, or on times and places that don't convert.
- What good looks like: location set to presence, adjustments based on real conversion data by region, time and device, and audience signals that genuinely describe your buyer.
- Red flag: the Presence or interest location default again (cross-check with area 1), plus device or schedule adjustments that were guessed rather than read from the data.
The 2026 automation layer: PMax, AI Max and signals
- Check: Performance Max brand exclusions, channel and placement distribution, AI Max query drift, the branded-versus-non-branded performance split, and attribution-model consistency.
- Why it matters: automation is a black box that will happily claim credit for traffic you'd have won anyway. Auditing it is where most checklists stop and where the money often hides.
- What good looks like: brand terms excluded from PMax where you run separate brand search, sensible channel distribution, query drift monitored, and a consistent (usually data-driven) attribution model.
- Red flag: PMax with no brand exclusions inflating its own results, a large share of spend drifting to Display or cheap placements, or AI Max serving on queries far from your intent.
This eighth area is the one that separates a 2026 audit from a 2021 one. A checklist that still audits only manual keywords, Quality Score and extensions is auditing an account that no longer exists. The automation layer now spends a meaningful share of most accounts’ budget, and it needs the same scrutiny as everything else, arguably more, because it hides its workings.
Are free Google Ads audits worth it?
It depends on what you want from one. A free Google Ads audit, the kind offered by agencies and one-click tools, is usually a lead-generation device, not a diagnostic. It runs an automated rules check, hands you a score and a colour-coded report, and books a sales call. That isn’t dishonest, but it’s worth knowing what you’re getting: a surface scan designed to start a conversation, not a deep read of your account.
A genuine audit takes expert hours. Working through the eight areas above, reading the search-terms report line by line, untangling whether PMax is cannibalising brand, checking attribution and consent, that’s judgement work, and judgement doesn’t come free or instant. The honest version is that an automated tool can flag the obvious (no negatives, missing extensions, a disapproved ad), but it can’t tell you that your tracking is double-counting, or that your best campaign is budget-throttled while a weak one runs hot.
So use the free tools for what they’re good at, a quick sniff test, then either run the full framework yourself or have someone do it properly. If you’d like us to run a real audit on your account, we’ll read it the way this guide describes, not the way a one-click tool does.
Turn your findings into a prioritised action plan
A list of 30 issues isn’t an action plan; it’s a to-do list that never gets done. The mistake most checklists encourage is treating every flag as equal. Firewire’s lens is revenue-first: rank each finding by the money it recovers or unlocks, then fix in that order.
In practice that means a single mistracked conversion (which corrupts every bidding decision) outranks a dozen missing sitelinks, even though the sitelinks are quicker to fix. A budget cap throttling your highest-ROAS campaign outranks a tidy-up of ad-group naming. Work top-down by impact: the fix that recovers the most wasted spend or unlocks the most profitable scale goes first, and the cosmetic items wait.
A quick worked example. Say the audit finds three things: a leaky search-terms list burning an estimated $800 a month, a Quality Score issue costing maybe $200 a month in higher clicks, and inconsistent naming costing nothing but tidiness. The order is obvious: kill the wasted $800 first, fix the $200 next, and leave the naming for a rainy day. That’s the whole discipline, sort by dollars, not by how many boxes are unticked.

You can run this audit yourself. The framework is right here, and if you know the Google Ads interface and have a few focused hours, you’ll catch the big leaks. That’s the point of writing it out, plenty of accounts are improved by an owner who simply sat down and worked the eight areas properly for the first time.
Where a professional earns the fee is in the judgement calls and the time. Untangling whether PMax is cannibalising brand, reading attribution honestly, knowing that an Australian account’s signal-density problem calls for consolidation rather than more campaigns, that’s pattern recognition built over many accounts. And realistically, most business owners don’t have an uninterrupted afternoon to read a search-terms report line by line. If the account is about to scale, the cost of getting the audit wrong is higher than the cost of having it done right. That’s the trade-off, and it’s an honest one: do it yourself if you have the time and confidence, or have our Google Ads team run it if the stakes or the hours don’t add up.
What a properly audited account can do
The Good Feet Store came to us with a paid search account that was burning budget without lead-quality discipline, cost-per-lead too high to scale, and ten retail locations competing for the same budget with no regional logic. The audit and rebuild that followed, exact-match restructure, geo-targeting per location, then a video layer, turned it into a predictable lead engine.
An underperforming account, rebuilt into a scalable lead engine.

What is a Google Ads audit?
A Google Ads audit is a structured review of an account’s structure, tracking, keywords, bidding, ads, Quality Score, targeting and automation to find where performance and budget are being lost, and what to fix first. The goal is a prioritised action plan, not just a score.
Is a PPC audit the same as a Google Ads audit?
In practice, yes. “PPC” (pay-per-click) is the broader category covering Google Ads, Microsoft Ads and other paid-search platforms, so a PPC audit uses the same method as a Google Ads audit. If your spend is all on Google Ads, the two are effectively identical.
How much does a Google Ads audit cost?
A genuine audit is usually charged as a one-off project or hourly, often in the $75 to $200 per hour range in Australia for expert work, with a full account audit taking several hours. Many agencies offer a free Google Ads audit, but those are typically a lighter, automated scan designed to start a sales conversation rather than a deep diagnostic.
How long does a Google Ads audit take?
A thorough audit of a mid-sized account usually takes a few hours of focused work, more for large or complex accounts with Performance Max, multiple locations or messy tracking. An automated tool returns a report in minutes, but it reads the surface, not the system.
How often should I audit my Google Ads account?
Run a full audit quarterly for an active account, with a lighter monthly check on conversion tracking, search terms and budget pacing. Also audit at key moments: inheriting an account, an agency handover, a performance plateau, or before you scale spend.
Are free Google Ads audits any good?
They’re useful as a quick sniff test. A free Google Ads audit will flag obvious issues like missing negatives or extensions, but it’s usually a lead-generation tool, not a diagnostic, and it can’t make the judgement calls (is tracking double-counting, is PMax cannibalising brand) that a real audit turns up.
Can I audit my own Google Ads account?
Yes. If you know the Google Ads interface and follow a structured framework like the eight areas in this guide, you can run a genuine audit yourself and catch the biggest leaks. A professional adds judgement built across many accounts and the time to read the detail, which matters most when you’re about to scale spend.
The audit is only worth the fixes you make
A Google Ads audit doesn’t recover a dollar on its own. The value is in the action plan it produces and the discipline to work it in order, biggest leak first. Run the eight areas, log every finding against the money it costs, and fix from the top down. Do that and a tired account starts working like the revenue channel it was meant to be.
If you’d rather we ran the audit and made the fixes, that’s exactly what our Google Ads team does. We’ll read your account the way this guide describes, tell you honestly where it’s leaking, and show you what we’d recover first.
