How to Audit Your Google Ads Account: A Step-by-Step Checklist for Australian Businesses in 2026

Most Australian SMEs are quietly bleeding 20-40% of their Google Ads budget every single month. Not because their products are bad, not because Google Ads does not work, but because nobody has sat down and systematically reviewed the account. Search terms are triggering irrelevant clicks. Negative keyword lists are empty. Conversion tracking is broken or was never set up correctly in the first place. Location targeting is set to "presence or interest" instead of "presence only," which means ads are showing to people in other countries who have simply searched for an Australian location.

A Google Ads audit is not glamorous work. It does not involve a new creative concept or a clever campaign idea. It involves going through your account area by area, comparing what you intended against what is actually happening, and fixing the gap. Done properly, a structured audit is one of the highest-ROI activities you can do in digital marketing. I have seen accounts where a single afternoon of audit work reduced cost per lead by more than 60% within 90 days. I have also seen accounts where years of agency "management" had never once produced a negative keyword list beyond the default handful Google suggests at setup.

This guide gives you the complete 12-point Google Ads audit checklist I use when reviewing accounts for Australian businesses. Whether you are doing this yourself or handing it to a specialist, this is the framework that finds the leaks and prioritises the fixes. If you want to understand how this audit fits into a broader paid media strategy, you can read about our approach to paid media at 3P Digital.

Key Takeaways

• Australian SMEs waste an estimated 20-40% of Google Ads spend on irrelevant searches, poorly configured settings, and untracked conversions. An audit recovers that waste.

• A 12-point audit covers: campaign structure, keyword match types and negatives, search term reports, Quality Score, ad copy and extensions, landing page alignment, bidding strategy, audience targeting, Australian-specific geographic and language settings, conversion tracking, budget pacing and dayparting, and competitor benchmarking via Auction Insights.

• Australian-specific settings (location targeting method, timezone, GST in reporting interpretation) are missed by the majority of SME accounts and by many agencies that do not work primarily in the Australian market.

• A proper audit should be conducted at minimum every quarter, or immediately if your cost per conversion has risen by more than 15% without a corresponding increase in competition or spend.

• DIY audits are feasible for simple single-campaign accounts. Accounts running more than three campaigns across multiple products or services will benefit from a specialist review, particularly for conversion tracking validation and bidding strategy assessment.

• Businesses that complete structured audits consistently report 30-60% improvements in cost per conversion within 90 days of implementing the identified fixes.

Summary Table: Google Ads Audit Areas at a Glance

Why Most Google Ads Accounts Leak Budget

Before getting into the checklist itself, it is worth understanding the underlying mechanics of why Google Ads accounts deteriorate over time, because an audit is not a one-off fix. It is a recurring discipline.

Google Ads operates on an auction system where relevance, bid, and expected click-through rate determine ad placement and cost. The platform is designed to spend your budget. Google's machine learning systems are optimised to find conversions, but they need clean data to do it. When conversion tracking is broken, when match types are too broad, or when the landing page experience is poor, Google's algorithms will still spend your budget. They just will not spend it well.

The average Australian Google Ads account has three structural problems that compounding over time produce dramatic waste:

Problem 1: Keyword sprawl without containment. Broad and broad match modifier keywords without robust negative keyword lists cause your ads to show for searches that have no commercial intent. A Melbourne law firm running a broad match keyword for "employment law" will trigger ads for "employment law essay help," "employment law textbook," and "what is employment law." None of those searchers are potential clients.

Problem 2: Conversion tracking that was never properly validated. I cannot tell you how many times I have audited an account and found conversion actions that were double-counting, counting micro-conversions as primary goals, or simply not firing at all. When your bidding strategy is optimising toward phantom conversions, every decision the algorithm makes is based on corrupted data. Our analytics team spends a significant portion of every audit specifically on this issue, because broken tracking is the root cause of more wasted spend than almost any other factor.

Problem 3: Set-and-forget campaign management. Google Ads accounts require ongoing governance. A campaign that was performing well 18 months ago may now be leaking budget because competitors have changed their strategy, your industry's search behaviour has shifted, or Google has quietly changed a default setting. Search term reports, in particular, need to be reviewed weekly or fortnightly, not monthly.

The other factor specific to Australia is that many businesses use agencies or freelancers who manage accounts designed for the US or UK market. Australian-specific configuration, from correct timezone settings to location targeting methodology and the interpretation of reporting data against GST-inclusive pricing, is frequently missed.

The 12-Point Google Ads Audit Checklist

1. Campaign Structure

A well-structured Google Ads account is not just tidier. It directly influences Quality Score, ad relevance, and your ability to control budget allocation at a granular level.

The standard you are looking for: each ad group should contain a tightly related cluster of keywords that map to a single theme. If you are a Sydney conveyancing firm, you should have separate ad groups for "property conveyancing Sydney," "conveyancing fees Sydney," and "first home buyer conveyancing" rather than lumping all three into one ad group with one set of ads.

What to check during the audit:

• How many keywords per ad group? More than 15-20 closely related keywords in a single ad group is a warning sign.

• Are campaigns separated by funnel stage? Brand, competitor, generic, and long-tail intent keywords should sit in separate campaigns so you can control budget and bids independently.

• Are Search and Display campaigns separated? Google defaults to including Display Network in Search campaigns. This dilutes your data and usually reduces ROI on Search budget. Verify they are split.

• Are Shopping and Search campaigns using the same budget pool? They should not be.

• Is there a clear naming convention? Account organisation that cannot be understood by a new person in five minutes is account organisation that will degrade over time.

Single Keyword Ad Groups (SKAGs) were a popular structure a few years ago and are now largely unnecessary given responsive search ads and Google's improved auction logic. But single theme ad groups remain the structural gold standard in 2026.

2. Keyword Match Types and Negative Keywords

Match type strategy is one of the highest-impact areas in any Google Ads audit. Get this wrong and you are paying for traffic with zero chance of converting.

Broad match keywords give Google maximum latitude to match your ads to related searches. In theory this captures demand you did not anticipate. In practice, without a mature negative keyword list and sufficient conversion data to inform Smart Bidding, broad match burns budget on irrelevant queries faster than almost any other setting.

Exact match and phrase match give you more control at the cost of reach. The right distribution depends on your account maturity, budget size, and how much conversion data you have accumulated.

What to check:

• What percentage of your spend is going to broad match keywords with fewer than 50 conversions tracked? That is almost always a waste.

• When was your negative keyword list last updated? It should be built from search term report analysis (see step 3) on at least a fortnightly cadence.

• Do you have a shared negative keyword list applied across all campaigns? Brand exclusions, competitor exclusions, and irrelevant intent terms (free, DIY, jobs, careers, Wikipedia) should be in a shared list applied universally.

• Are you using negative keyword lists at the campaign level as well as ad group level?

• Do your negative keywords include common misspellings and plurals for your highest-wasted-spend terms?

A practical example: when I audited the Google Ads account for a Queensland building and pest inspection business, the negative keyword list had 12 entries. After analysing 90 days of search term data, we identified 340 irrelevant query patterns and built a negative keyword list of over 200 terms. Within six months, the account generated 574 additional leads while reducing cost per conversion by 63.5%. The negative keyword work was a significant driver of that outcome.

3. Search Term Report Analysis

The search term report is the single most actionable document in your Google Ads account. It shows you the actual queries people typed before clicking your ad. The gap between what you intended to target and what is actually triggering your ads is where most budget waste lives.

Accessing the report: Campaigns > Keywords > Search Terms. Filter for the last 30, 60, and 90 days to get a representative sample.

What to look for:

• Queries with zero relevance to your product or service that have generated clicks. These become negative keywords immediately.

• High-spend, high-click queries with zero conversions. These need investigation. Is the landing page relevant? Is the intent informational rather than commercial? Should you add them as negatives?

• High-converting queries that are not currently in your keyword list as exact match. Add them explicitly so you can bid more aggressively on what actually works.

• Brand term queries you are paying for when you could capture them with a separate low-bid brand campaign or organic ranking.

• Competitor brand queries. Are you deliberately targeting competitors? If not and competitor brand queries are triggering your ads, you may want to add them as negatives or build a deliberate competitor campaign with tailored messaging.

The search term report review should not be a once-per-quarter exercise. For accounts spending more than $5,000 per month, review it weekly. For smaller accounts, fortnightly.

4. Quality Score Review

Quality Score is Google's 1-10 rating of the relevance and quality of your keywords, ads, and landing pages. A higher Quality Score means lower cost per click for the same ad position. A score of 7 or above is generally healthy. Scores of 4 or below are costing you money on every single click.

Quality Score has three components: expected click-through rate (eCTR), ad relevance, and landing page experience. Each is rated as above average, average, or below average.

What to check:

• Filter your keyword list by Quality Score. Sort ascending to surface your worst performers first.

• For keywords scoring 4 or below, identify which component is dragging the score down. A "below average" landing page experience means Google does not think your destination page is relevant to the keyword and search query. A "below average" ad relevance means your ad copy does not contain the keyword or its close variants.

• Are your ad groups tightly themed enough that the keyword naturally appears in the ad copy? If you have 40 keywords in one ad group with a generic headline, every keyword in that ad group is suffering from poor ad relevance.

• Check historical Quality Score trends using tools like Google Ads Editor, or segment by time period in the interface. Is your average score improving or declining?

For a detailed breakdown of how Quality Score works and how to improve it, we have a dedicated guide on Google Ads Quality Score for Australian businesses.

5. Ad Copy and Extension Audit

In 2026, Responsive Search Ads (RSAs) are the standard format for Search campaigns. RSAs allow you to enter up to 15 headlines and 4 descriptions, and Google's system tests combinations to find the best performers. This creates both opportunity and a common trap.

The trap: many advertisers pin their headlines, locking Google into showing only specific combinations and defeating the purpose of RSAs entirely. Others create one RSA per ad group and never test alternatives.

What to check for ad copy:

• Is each ad group using at least two RSA variants for testing? One RSA is not enough for meaningful comparison.

• Are you pinning headlines? Pinning is only appropriate in specific compliance-driven situations (legal or regulated industries where certain disclosures must appear). Otherwise, unpin and let the system test.

• Does your highest-traffic RSA have a "Good" or "Excellent" ad strength rating in the interface? "Poor" ad strength is a warning sign.

• Are your headlines genuinely differentiated in value proposition, not just slight rewording of the same claim?

• Do your ads include the primary keyword in at least one headline?

• Does your copy have a clear call to action that matches what the landing page is asking visitors to do?

What to check for extensions (now called Assets in the Google Ads interface):

• Sitelink extensions: Are you running at least six sitelinks per campaign? Are they pointing to relevant, functional pages?

• Callout extensions: Do you have at least eight callouts that communicate genuine differentiators, not generic claims like "quality service"?

• Structured snippets: Are they completed for relevant categories?

• Call extensions: Is your business phone number connected and set to show during your actual business hours?

• Lead form extensions: For service businesses, have you tested lead form assets to capture enquiries directly from the search results page?

• Promotion extensions: If you run seasonal promotions, are they active and correctly scheduled?

• Price extensions: For e-commerce or service businesses with standard pricing, are price assets in use?

Missing extensions is free money left on the table. Extensions increase your ad's visible footprint on the search results page and improve CTR without increasing cost per click.

6. Landing Page Alignment

A click is only worth something if the landing page converts it. The most common and most expensive landing page mistake I see in Australian SME accounts is sending all paid search traffic to the homepage.

Your homepage is designed to communicate the breadth of what you do. A search ad is targeting a specific intent. Sending someone who searched "emergency plumber Parramatta" to your homepage and expecting them to navigate to a contact form is asking too much. They will leave. You have paid for that click and got nothing.

Message match is the principle that the headline and value proposition on your landing page should directly mirror the promise made in your ad. If your ad headline reads "Fixed Price Conveyancing from $990," your landing page should lead with that same offer.

What to check:

• For each campaign, click through from the ad preview to the destination URL. Does the page content match the ad's promise?

• Test your landing page load speed using Google's PageSpeed Insights. Pages taking more than three seconds to load on mobile lose a significant percentage of visitors before they see the content. In Australia, mobile traffic accounts for more than 60% of Google Ads clicks across most industries according to Google's own benchmarks.

• Is there a single, clear call to action above the fold? Are there competing CTAs confusing the visitor about what to do next?

• Is the landing page mobile-optimised? Test on an actual mobile device, not just a browser resize.

• Does the page contain the primary keyword in the H1 heading? This contributes to Quality Score's landing page experience component.

• Is there social proof (testimonials, case studies, review counts) visible on the page without scrolling?

For businesses serious about improving landing page conversion rates, our conversion optimisation service takes a data-led approach to exactly this problem.

7. Bidding Strategy Assessment

Google Ads offers a range of bidding strategies, from fully manual CPC to automated Smart Bidding strategies like Target CPA, Target ROAS, Maximise Conversions, and Enhanced CPC. The right strategy depends on your account's maturity and the volume of conversion data you have available.

The most common mistake I see in Australian SME accounts is using automated Smart Bidding strategies without sufficient conversion data to support them. Target CPA bidding requires a minimum of 30-50 conversions per month per campaign to function reliably. Below that threshold, the algorithm does not have enough signal to make intelligent bid decisions and will overpay for some clicks while missing others entirely.

What to check:

• Which bidding strategy is each campaign using? Is it appropriate for that campaign's conversion volume?

• For campaigns using Target CPA or Target ROAS, how does the actual CPA or ROAS compare to the target over the last 30 days? If actual CPA is consistently 50% above target, either the target is too aggressive or there is insufficient data.

• Are any campaigns still on Manual CPC that have enough conversion data to benefit from Smart Bidding? Manual CPC is appropriate during account setup or when testing new campaigns, but it is not optimal long-term.

• Is Target Impression Share being used appropriately? This strategy is designed for brand awareness, not lead generation. Using it for lead gen campaigns is a classic mistake.

• For e-commerce clients, is Target ROAS set based on actual margin data, not just revenue, so the strategy is optimising toward profitability?

Bidding strategy changes have a learning period of approximately 7-14 days during which performance may fluctuate. Do not evaluate a new strategy immediately after switching.

8. Audience Targeting

Audience targeting in Search campaigns is one of the most underutilised levers in Google Ads. Most Australian SME accounts have either no audiences applied or only the default Google audiences with no bid adjustments based on actual performance data.

There are two modes for applying audiences to Search campaigns: Observation (your ads still show to everyone, but you can see how different audiences perform and apply bid adjustments) and Targeting (your ads only show to people within the selected audiences). Observation mode is how you gather data before making targeting decisions.

What to check:

• Are In-Market audiences relevant to your industry applied in Observation mode? Check performance data by audience segment and apply positive bid adjustments to high-converting segments.

• Do you have a remarketing list (website visitors) applied? People who have already visited your site and are searching again are much higher value. Remarketing Lists for Search Ads (RLSA) allow you to bid more aggressively for these users.

• Do you have Customer Match lists uploaded? Existing customers or leads in your CRM can be used to adjust bids or exclude people who have already converted.

• Are you excluding audiences that should not see your ads? If you are a B2B business, you may want to exclude Consumer audiences. If you sell premium services, excluding audiences associated with bargain-seeking behaviour is often worthwhile.

• Are demographic bid adjustments being used based on actual performance data? Age, gender, and household income layers (limited in Australia but available) can reveal significant performance variations.

9. Geographic and Language Settings for Australia

This is the section most impactful for Australian advertisers and most commonly done wrong. The consequences of incorrect geographic targeting are real: your ads show to people outside your serviceable area or even outside Australia entirely, and you pay for every click.

Location targeting method. This is the single most important setting to check in any Australian Google Ads account. Navigate to Campaign Settings > Locations > Location Options. You will see two options:

• "Presence or interest: People in, regularly in, or who've shown interest in your targeted locations" (this is the default)

• "Presence: People in or regularly in your targeted locations"

The default setting is wrong for most Australian advertisers. "Presence or interest" means your Melbourne accounting firm's ads will show to someone in the United States who searched for "Melbourne accountant." They are not your potential client. You are paying for that click.

Change all campaigns to "Presence only" unless you have a specific reason not to. This single change alone has recovered meaningful budget waste in every account where I have found it misconfigured.

Location exclusions. Within your targeted areas, are there suburbs, regions, or postcodes that generate clicks but never convert? Add them as excluded locations. For example, a Perth business that consistently sees clicks from regional WA locations it cannot service should exclude those postcodes.

Language settings. For most Australian businesses, English is the correct setting. However, if you are targeting communities where another language is commonly spoken (Mandarin-speaking communities in Sydney or Melbourne, for example), you may want to consider separate campaigns with appropriate language settings and localised ad copy.

Timezone. Verify that your account timezone is set to Australian Eastern Standard Time (AEST) or AEDT if your primary market is on the east coast, or the correct timezone for your primary market. An account set to a US timezone will show ads at the wrong hours and make your dayparting analysis meaningless.

GST in reporting. Google Ads charges in AUD for Australian accounts, but cost reporting in the interface does not include GST. Your actual cost is 10% higher than what is shown. When reporting to clients or internal stakeholders, make this clear. A reported CPA of $45 in the interface is $49.50 including GST. For businesses managing tight margins, this distinction matters.

For a thorough guide on managing your Google Ads budget with these considerations in mind, see our Google Ads budget management guide for Australian small businesses.

10. Conversion Tracking Validation

If campaign structure is the skeleton of your account, conversion tracking is the nervous system. Nothing else matters if conversion tracking is broken, because every automated decision Google makes is based on this data.

Conversion tracking validation is not a check you do once at account setup and forget. Tags break when websites are updated, when CMS plugins are changed, or when developers modify site code without realising they have removed a tracking tag.

What to check:

• Open Google Tag Assistant or use the Google Ads Tag Diagnostics tool. Are all conversion tags firing correctly and recently?

• Are conversions being counted with the right counting method? "Every conversion" is appropriate for purchases. "One conversion per click" is appropriate for leads, because a single user submitting your contact form five times should not count as five conversions.

• Is the attribution model appropriate for your business? Last click attribution under-credits upper-funnel keywords. Data-driven attribution is the recommended model for accounts with sufficient conversion volume (generally 300+ conversions in 30 days). For smaller accounts, last click or time decay are defensible choices with clear logic.

• Is the conversion window correct? The default 30-day conversion window is appropriate for most lead generation businesses. For considered purchases with long decision cycles (property, financial services, B2B software), extending the window to 60 or 90 days captures conversions that would otherwise be missed.

• Are you tracking phone call conversions? For service businesses in Australia, phone calls from ads and from the website are often the highest-intent conversion action. Google Ads call tracking and Google forwarding numbers enable this measurement.

• Are micro-conversions (page views, scroll depth) being tracked as separate secondary actions, not as primary conversion goals? Setting a "visited contact page" micro-conversion as a primary goal inflates conversion numbers and corrupts Smart Bidding.

• Does your conversion data reconcile with your CRM? If Google Ads is reporting 80 conversions last month but your CRM shows 40 qualified enquiries, something is double-counting or tracking low-quality interactions.

I treat conversion tracking validation as the critical path item in every audit. Everything else is secondary until you know the data is clean.

11. Budget Pacing and Dayparting

How your budget is distributed across the day and week has a direct impact on your cost per conversion. Not all hours and days are equal in terms of conversion intent.

What to check:

• Navigate to Reports > Time > Hour of Day. Where are your clicks concentrated versus where are your conversions concentrated? If you are spending heavily between 10pm and 2am but conversions occur between 8am and 6pm, you are wasting budget on low-intent browsing traffic.

• Check Day of Week performance. Many B2B service businesses see dramatically lower conversion rates on weekends, but budgets continue to spend evenly across the week.

• Are any campaigns set to Standard delivery versus Optimised delivery? Optimised delivery (the current Google default) distributes budget using predictive signals. Standard delivery spreads spend evenly throughout the day. For most accounts, Optimised is preferable.

• Is your daily budget being fully consumed before the end of the day (100% budget utilisation with budget lost)? This indicates you should either increase budget or improve Quality Score to get more value from existing spend.

• For campaigns with business-hours-only conversion opportunities (phone calls, appointments), have you applied negative bid adjustments or ad scheduling exclusions for out-of-hours periods?

Dayparting based on insufficient data is a common mistake. Do not make significant bid adjustments based on fewer than 30 days of data per time segment. The insights need statistical weight to be actionable.

12. Competitor Benchmarking via Auction Insights

Auction Insights is a free, underused report inside Google Ads that shows you how your campaigns overlap with competitors in the same auctions. It does not show competitor keywords or bids, but it shows performance metrics that indicate your competitive position.

The metrics to review:

• Impression Share: What percentage of eligible impressions is your campaign capturing? Lost Impression Share is split into "lost to budget" and "lost to rank." This tells you whether you are losing visibility because you are outbid or simply because your daily budget runs out.

• Overlap Rate: How often a competitor's ad appeared in the same auction as yours.

• Position Above Rate: How often a competitor's ad appeared above yours when both were shown.

• Top of Page Rate: What percentage of the time your ads appeared above the organic results.

• Absolute Top of Page Rate: What percentage of the time your ads appeared in position one.

What to do with this data:

• If your lost Impression Share is predominantly "lost to budget," consider whether budget reallocation from lower-performing campaigns can shore up your most important campaigns before increasing overall spend.

• If you are consistently below a specific competitor in Position Above Rate, investigate their ad copy, extensions, and Quality Score. Better ad relevance and landing page quality can improve position without increasing bids.

• If your Impression Share has dropped significantly over the last 90 days with no change in your account, competitors have likely increased spend or quality. This is actionable competitive intelligence.

Australian-Specific Settings Most Advertisers Miss

Beyond the 12 checklist points above, there are a handful of configuration details specific to the Australian market that appear in almost every account I audit and are almost never addressed.

Location targeting method (expanded above in point 9) is the single most impactful Australia-specific setting. I include it again here because it deserves double emphasis. Change it to "Presence only" across every campaign.

Ad scheduling and AEST/AEDT. Australia observes Daylight Saving Time in some states (New South Wales, Victoria, South Australia, Tasmania, Australian Capital Territory) but not others (Queensland, Western Australia, Northern Territory). If you are running national campaigns and using ad scheduling based on business hours, your schedule will be off by one hour for half the country during the October-April daylight saving period. Build this into your scheduling logic.

Currency and GST reporting. As noted above, Google Ads reporting does not include GST. Your finance team and clients need to understand that every cost figure from Google Ads needs a 10% uplift for true cost of advertising. When calculating CPA for reporting or bidding strategy targets, account for this. A Target CPA of $100 in the platform represents a true cost of $110 including GST.

Australian consumer law compliance in ad copy. The Australian Competition and Consumer Commission (ACCC) takes a firm position on misleading or deceptive advertising, including in digital channels. Claims in your ad copy must be substantiated. Terms like "Australia's leading," "number one," or "cheapest" require evidence. This is not just a best practice issue. It is a compliance issue under the Australian Consumer Law.

Financial services and regulated industries. If you are advertising in financial services, credit, insurance, or health, there are specific Google Ads policies for Australia that overlay the ACCC requirements. Mortgage brokers advertising in Australia must comply with both ASIC guidance on financial advertising and Google's Financial Services policies. Credit products require specific disclaimers. Build these into your ad copy review process.

Case Studies: What a Proper Audit Delivers

Case Study 1: Queensland Building and Pest Inspection Business

I was brought in to review a Google Ads account for a Queensland building and pest inspection business that had been running for 18 months with a Sydney-based agency managing it. The account was spending approximately $8,000 per month. The business owner's concern was simple: the cost per booking was rising and volume was flat.

The audit took approximately four hours. What we found:

• The negative keyword list had 12 entries, all Google defaults from setup. The search term report showed the account had spent over $1,400 in the previous 90 days on queries including "building inspection courses," "pest inspection training," "pest control DIY," and "building and pest inspection report template." None of these were potential customers.

• Location targeting was set to "Presence or interest," meaning ads were serving to users outside Queensland who had searched for Queensland-related terms. Roughly 8% of spend was going to non-Queensland traffic.

• Conversion tracking was measuring "Thank You page visits" as the primary conversion, but the Thank You page was also accessible via a link in the footer navigation, meaning direct navigation to that page was being counted as a conversion. Actual lead volume was being overstated by approximately 30%.

• The account had no audiences applied and no dayparting, despite the client's data showing almost no bookings came in after 7pm or before 7am.

Within six months of implementing the identified fixes, the account generated 574 additional leads while reducing cost per conversion by 63.5%, with average cost per click falling by $12.56. That is not a marketing story. That is an operations story. The spend did not change materially. The waste was eliminated.

Case Study 2: B2B Professional Services Firm, National

A national B2B professional services firm came to us after running Google Ads for two years with no meaningful inbound pipeline from the channel. Their previous agency had been sending monthly reports showing healthy click volumes and reasonable CTRs. The account looked fine on the surface metrics. It was not fine.

The full audit, which included a complete digital marketing review aligned to our 3P Framework, revealed:

• The primary campaign was targeting keywords at a generic, informational intent level. The search terms triggering ads were overwhelmingly people in the research phase, not buyers. The account had never been mapped against the actual decision-making journey of a B2B buyer in this industry.

• There was no remarketing set up. A B2B buyer with a 60-90 day consideration cycle who visited the site once was never seen again by the campaign.

• Landing pages were the company homepage and a generic "services" page. There was no message match between the ad copy promises and the landing page content.

• Conversion tracking was set to track a newsletter sign-up as the primary conversion goal. This was being used to inform the Smart Bidding algorithm. The account was literally optimising toward attracting newsletter subscribers rather than sales enquiries.

After rebuilding the campaign structure, fixing conversion tracking, creating intent-matched landing pages, and layering in remarketing, qualified inbound enquiries increased by 247% within 12 months. The agency they had used before was not incompetent. They were producing activity reports rather than results. The metrics they were reporting looked fine. The business outcome was not fine.

This is the exact trap our pay-per-performance model is designed to avoid. We only succeed when you succeed.

What a Good Google Ads Performance Benchmark Looks Like in Australia

Before prioritising your audit fixes, it helps to know what "good" looks like in the Australian market. Benchmarks vary significantly by industry, but these figures provide a working reference.

Click-Through Rate (CTR): The average CTR across Australian Google Search campaigns sits in the range of 3-6% for well-managed accounts. Below 2% across an entire campaign is a signal that ad relevance, Quality Score, or extension completeness needs attention.

Cost Per Click (CPC): Australian CPCs are generally higher than US equivalents due to smaller audience scale. Industry benchmarks range from $2-4 for e-commerce to $15-40+ for legal, financial services, and insurance. If your CPC is significantly above category benchmarks, Quality Score improvement and negative keyword work should be the priority.

Conversion Rate: Average conversion rates across Australian lead generation accounts typically range from 2-8% depending on industry and how tightly conversion actions are defined. If your account shows a 15% conversion rate, verify that your conversion actions are genuinely measuring qualified intent and not micro-conversions.

Cost Per Acquisition (CPA): This varies too widely by industry to give a single benchmark, but a useful internal benchmark is your target customer lifetime value multiplied by acceptable acquisition cost percentage. A mortgage broker whose average client generates $3,000-5,000 in commission can afford a materially higher CPA than a business selling $50 products.

How to Prioritise Fixes After Your Audit

A thorough audit will surface more issues than you can fix at once. Trying to address everything simultaneously creates instability and makes it impossible to attribute performance changes to specific fixes. Here is how I approach prioritisation.

Tier 1: Fix immediately (within 48 hours)

• Conversion tracking that is broken or misconfigured

• Location targeting set to "presence or interest" instead of "presence only"

• Obvious budget waste (search terms with significant spend and zero relevance)

• Any campaign actively spending budget toward the wrong objective

Tier 2: Fix within the first two weeks

• Negative keyword list expansion based on search term report analysis

• Landing page misalignment (creating or updating destination pages to match ad copy)

• Missing or incomplete extensions

• Bidding strategy mismatches (campaigns using Smart Bidding without adequate conversion data)

Tier 3: Fix within the first month

• Ad copy testing and RSA optimisation

• Audience layering and RLSA implementation

• Dayparting based on time-of-day performance data

• Campaign structure refinement

Tier 4: Ongoing governance

• Weekly search term report reviews and negative keyword additions

• Monthly Auction Insights review

• Quarterly full audit against this checklist

• Attribution model review as conversion data accumulates

The reason this sequencing matters is that Google's Smart Bidding needs clean conversion data before it can do anything useful. Tier 1 and Tier 2 work cleans the data and removes the waste. Only then does the algorithm have the right signals to optimise bidding toward your actual goals. Skipping straight to bidding strategy changes without fixing the data underneath is one of the most common mistakes agencies make.

This is the same sequencing logic behind the 3P Framework: Profile and Plan before Perform. You need to understand what is happening before you change how you respond to it. You can see how this framework applies across all our client engagements on our case studies page.

When to Bring In a Specialist

A DIY audit is entirely feasible for a single-campaign, straightforward account. If you are a sole trader running one Search campaign with a clear product, a modest budget under $3,000 per month, and a well-defined target audience, working through this checklist yourself will surface the majority of issues.

Bring in a specialist when:

• Your account runs more than three campaigns across different products, services, or funnel stages

• You have Shopping campaigns alongside Search campaigns

• Your conversion tracking involves multiple touchpoints, CRM integration, or phone call tracking

• You are spending more than $5,000 per month and cost per lead has been rising for more than 60 days

• Your account has been managed by a previous agency and you are unsure what configuration decisions were made or why

• You are in a regulated industry (financial services, health, legal) where compliance requirements add a layer of complexity to ad copy review

• You want to implement Offline Conversion Tracking to connect Google Ads data to closed deals in your CRM

The cost of a professional audit from a specialist agency ranges from $500 to $2,500 depending on account complexity, spend level, and depth of analysis. For an account spending $10,000 per month, recovering 20% waste through an audit pays back the audit cost in the first month. For accounts with the kind of structural issues I have described above, the return is often significantly higher.

At 3P Digital, our Google Ads audits are conducted as part of a broader paid media review that evaluates not just account configuration but the strategic alignment between your campaigns, your ideal customer profile, and your conversion infrastructure. If you want to understand what that looks like, get in touch with our team.

"The audit identified issues our previous agency had never raised in 18 months. Within three months of implementing the recommendations, our cost per lead dropped by more than 50% and inquiry volume was up. The ROI on the audit itself was obvious within the first billing cycle." Managing Director, Queensland Professional Services Firm

Tools to Help You Conduct Your Google Ads Audit

Beyond the Google Ads interface itself, these tools support specific aspects of the audit process:

Google Ads Editor: A free desktop application that allows bulk editing, account-wide keyword analysis, and structure review that is faster than working in the browser interface. Essential for any account with more than a handful of campaigns.

Google Tag Assistant (Legacy) and Tag Assistant Companion Chrome Extension: Validates that conversion tags are firing correctly on your website pages. Essential for conversion tracking validation.

Google PageSpeed Insights: Tests landing page load performance on both mobile and desktop. Free and directly relevant to Quality Score's landing page experience component.

Google Analytics 4 (GA4): Cross-referenced with Google Ads data to validate traffic quality, bounce behaviour, and conversion attribution. If your Google Ads and GA4 accounts are not linked, link them immediately. Our analytics team treats this integration as a foundational requirement for any audit.

SEMrush or Ahrefs: Useful for competitor ad copy research and identifying keyword gaps, though these are supplementary to the primary audit work done in Google Ads directly.

Google Keyword Planner: For identifying search volume and CPC benchmarks on potential keyword additions identified during the search term report analysis.

Optmyzr or Adalysis: Paid tools designed specifically for Google Ads auditing and optimisation at scale. Worthwhile for agencies and businesses managing multiple accounts.

Frequently Asked Questions

How often should I audit my Google Ads account?

For most Australian SMEs, a comprehensive audit should be conducted every quarter. If your account is spending more than $10,000 per month, a full audit every 6-8 weeks is more appropriate. Outside of scheduled audits, search term reports should be reviewed weekly, and performance metrics should be checked at least fortnightly. The trigger for an unscheduled audit is any sustained 15% or greater rise in cost per conversion that cannot be explained by seasonal factors or market-wide competition increases.

What does a professional Google Ads audit cost in Australia?

Professional Google Ads audits from specialist Australian agencies typically range from $500 to $2,500 depending on account complexity, campaign count, spend level, and the depth of conversion tracking and attribution analysis required. For accounts spending over $10,000 per month, expect to pay at the higher end for a thorough analysis that covers all 12 areas outlined in this checklist. The audit cost should be evaluated against the potential monthly waste it identifies. An account leaking $3,000 per month in wasted spend pays back a $1,500 audit fee within the first month of implementing fixes.

What are the most common mistakes found in Australian Google Ads accounts?

The five most common issues I find across Australian accounts are: (1) location targeting set to "presence or interest" instead of "presence only," allowing ads to serve outside Australia or outside the target service area; (2) empty or minimal negative keyword lists with no process for ongoing expansion from search term report analysis; (3) broken or misconfigured conversion tracking, including micro-conversions set as primary goals; (4) Smart Bidding strategies applied to campaigns without sufficient conversion data to support them; and (5) all paid search traffic directed to the homepage rather than intent-matched landing pages.

Can I audit my Google Ads account myself?

Yes, for single-campaign accounts with straightforward conversion tracking, this checklist provides everything you need to conduct a thorough DIY audit. The most technically demanding areas are conversion tracking validation (which requires familiarity with Google Tag Manager and GA4) and bidding strategy assessment (which requires an understanding of Smart Bidding data thresholds). If you are managing multiple campaigns, have integrated phone call tracking, or are running a combination of Search, Shopping, and Display campaigns, engaging a specialist will surface issues that are difficult to identify without platform-specific experience.

How long does a Google Ads audit take?

For a straightforward account with two to three campaigns, a thorough audit covering all 12 areas takes approximately two to four hours. For larger accounts with five or more campaigns, multiple ad formats, and integrated conversion tracking, expect six to ten hours for a complete review. This includes documenting findings and prioritising recommendations. Audits that include landing page analysis, GA4 reconciliation, and competitor benchmarking take longer but produce more actionable outputs.

What is a good CTR and CPC for Google Ads in Australia?

Across Australian Search campaigns, a healthy click-through rate sits in the range of 3-6% for well-managed accounts. Below 2% across an entire campaign is a signal to investigate ad relevance, extension completeness, and Quality Score. Average cost per click varies significantly by industry: e-commerce and retail typically run $2-5 per click, professional services run $8-20, and legal, financial services, and insurance can run $20-50 or higher due to high competition and customer lifetime value. If your CPC is consistently above category benchmarks, focus on Quality Score improvement and tighter keyword targeting before increasing bids.

How do I know if my conversion tracking is accurate?

Cross-reference three data sources: Google Ads conversion data, GA4 goal or event completions linked to the same actions, and your CRM or back-end enquiry data. If these three sources are broadly consistent (within 10-15% of each other), your tracking is likely reliable. Significant discrepancies indicate double-counting, broken tags, or incorrect conversion window settings. Use Google Tag Assistant to verify that conversion tags are firing on the correct pages and not on pages accessible via navigation. Check that conversion counting is set to "one conversion per click" for lead generation campaigns.

Should I use broad match or exact match keywords in Australia?

In 2026, the answer depends on your account's conversion data volume and Smart Bidding maturity. Broad match keywords perform well when paired with Smart Bidding strategies that have sufficient conversion data (30+ conversions per month per campaign) and a comprehensive negative keyword list. For newer accounts or accounts with limited conversion history, phrase match and exact match give you more control and reduce the risk of budget waste on irrelevant queries. The Australian market is smaller than the US, which means broad match reaches audience saturation faster. Start tighter and expand as your data builds, rather than starting broad and trying to contain the waste.
