Learn How to Undertake a Google Ads Audit

A Google Ads audit should ultimately answer three commercial questions:

1. How can the account reduce wasted spend and improve cost efficiency?
   Identify opportunities to lower cost per lead, cost per sale, or customer acquisition cost by improving targeting, campaign structure, conversion tracking and budget allocation.
   
   
2. Where can the account generate more leads or sales without reducing profitability?
   Find opportunities to scale successful campaigns, capture additional demand and increase volume while maintaining acceptable return on investment.
   
   
3. How can the account improve lead quality and measure true business performance?
   Ensure campaigns are optimised towards valuable outcomes by connecting advertising data with qualified leads, customers, revenue, customer lifetime value and return on ad spend.

That sounds straightforward, but many audits never reach those answers. They become long lists of settings, optimisation scores and generic recommendations copied from the Google Ads interface. The advertiser is told that Broad Match is missing, a campaign is limited by budget or an advert has only “Good” Ad Strength, without being told whether changing it would actually improve the business result.

A useful audit works differently. It distinguishes between:

• settings that are already correct and should be left alone;
• genuine problems that are wasting money or corrupting data;
• opportunities supported by account evidence; and
• ideas that should be tested rather than presented as guaranteed improvements.

It should also connect targeting, landing pages and Google’s AI bidding system. These are not independent parts of an account. Targeting determines which auctions the advertiser can enter, the landing page determines what happens after the click, and conversion data teaches automated bidding which users and outcomes to pursue.

Our guide to the three factors that determine Google Ads success explains this relationship in more detail.

This article sets out the practical audit process we use at One PPC, including the questions to ask, the reports to review and how to turn the findings into an implementation plan.

What Is a Google Ads Audit?

A Google Ads audit is a structured review of an account’s strategy, setup, targeting, measurement and performance. Its purpose is to identify the changes most likely to improve advertising results.

An audit is broader than routine optimisation.

Routine management may involve reviewing search terms, adding negative keywords, testing adverts and adjusting budgets. An audit steps back and asks whether the whole system is built correctly:

• Are the campaigns pursuing the right business goals?
• Are conversions being recorded accurately?
• Does Google know the difference between an enquiry and a valuable customer?
• Are campaigns reaching the right locations and search intentions?
• Do adverts and landing pages match those intentions?
• Is the account structure helping or obstructing budget control and reporting?
• Is automated bidding receiving enough accurate data to work effectively?
• Are Performance Max or AI Max expanding reach profitably, or merely claiming more traffic?

The outcome should not be “apply every Google recommendation”. It should be a prioritised plan supported by evidence from the account and, where possible, the CRM, ecommerce system or sales records.

What a Good Audit Should Contain

A written audit needs enough explanation to be useful to the business owner without burying the recommendations in definitions.

A practical format is to give every area one of four statuses:

The audit should explain what was found, why it matters and what should happen next. “Broad Match is active” is only an observation. “One Broad Match keyword is receiving most of the campaign’s spend and matching to several irrelevant themes; restrict it and add the identified negatives” is a recommendation.

The same principle applies when something is working. If auto-tagging, enhanced conversions or campaign goals are configured correctly, the audit should say so. Changing an account simply to demonstrate activity can destroy a reliable baseline and restart learning unnecessarily.

Start With Business Goals, Not Google Ads Settings

Before opening campaign reports, establish what the business considers a successful result.

For an ecommerce company, this may include:

• completed purchases;
• revenue;
• gross profit;
• new-customer acquisition;
• repeat purchases; and
• customer lifetime value.

For a lead-generation business, it may include:

• valid enquiries;
• Qualified Leads;
• booked or attended appointments;
• Sales Opportunities;
• accepted quotations;
• Closed Won customers; and
• revenue generated.

Also confirm the acceptable cost per lead, cost per customer or return on advertising spend. Consider margins, sales capacity, geographic coverage, priority products and services, seasonal demand and the speed at which leads are followed up.

Without this information, an auditor can describe the account but cannot judge it properly. A £60 lead might be excellent for one business and unaffordable for another. A campaign with a 500% ROAS might be highly profitable for one retailer but unviable for another with low margins and high return rates.

Select a Fair Audit Period

An audit needs enough data to separate a pattern from ordinary variation. The right period depends on spend, conversion volume, seasonality and how recently the account changed.

A useful starting point is often:

• the most recent 90 days;
• the preceding 90 days; and
• the equivalent period from the previous year where seasonality matters.

Do not assess only the account total. Segment performance by campaign, campaign type, brand and non-brand, product or service, device, location, network, audience, conversion action and landing page.

Account averages can be deceptive. One strong brand campaign may conceal weak non-brand acquisition. A Performance Max campaign may appear to outperform Search while collecting existing brand demand. A cheap lead source may produce few qualified opportunities after the sales team reviews the enquiries.

Allow for conversion delay as well. Recent days may appear weaker because some leads have not yet become opportunities or customers.

Review Change History Before Diagnosing Performance

The change history helps explain when and why performance moved. Compare important changes with changes in cost, conversion rate, CPA, ROAS and lead quality.

Look for:

• bidding-strategy or target changes;
• large budget adjustments;
• new campaigns or campaign consolidations;
• conversion actions being added or reclassified;
• match-type changes;
• new negative keywords;
• location or network changes;
• automatically applied recommendations;
• edits from scripts, integrations or third-party management tools; and
• periods in which tracking or the website failed.

The account may already have undergone several interventions. Without the history, an auditor can mistake the consequence of a recent change for a long-term structural problem.

Audit Conversion Tracking Before Judging Campaigns

Conversion tracking is the foundation of the audit because nearly every performance conclusion depends on it.

If a campaign reports 100 conversions, first establish what those conversions actually represent. They could be 100 purchases or genuine enquiries. They could also include thank-you-page reloads, duplicate GA4 imports, telephone-number clicks, page views and spam submissions.

Google’s bidding system cannot independently determine whether the advertiser has defined a useful conversion. If low-value actions are marked as Primary, the system can become very efficient at producing outcomes the business does not want.

Our Google Ads conversion tracking guide explains the main website, app, telephone and offline measurement methods.

Build a Conversion Inventory

Document every conversion action and review:

• its name and source;
• the business event it represents;
• whether it is Primary or Secondary;
• which campaigns use its goal;
• its value and currency;
• whether the count setting is appropriate;
• its attribution setting and conversion window;
• its recent status and diagnostics; and
• whether another action records the same event.

For lead generation, “One” is normally the appropriate count for a lead action because several submissions after one advert interaction may still represent one prospect. Ecommerce purchases generally use “Every” because each transaction has value. The correct choice depends on the event rather than a universal rule.

Where practical, One PPC generally prefers the native Google Ads tag for website actions used directly by Google Ads bidding. GA4 conversions can still be imported for additional reporting or when the implementation requires them, but duplicate Google Ads and GA4 versions of the same action must not both influence bidding.

Separate Primary and Secondary Conversions

Primary actions should normally represent the outcomes the campaign is intended to generate. Secondary actions provide supporting information without routinely directing bidding.

This is not just an account-level check. Review account-default goals and campaign-specific goals. A conversion can be categorised correctly but still influence the wrong campaign.

Read our guide to Primary and Secondary conversion actions for the detailed setup implications.

Test Conversions Rather Than Trusting the Status Label

An “Active” status does not prove that the complete journey is accurate. Undertake controlled tests and confirm that:

• the conversion fires only after the required action is completed;
• abandoned or invalid forms do not trigger success;
• confirmation-page reloads do not create duplicate conversions;
• embedded and multi-step forms preserve attribution;
• purchases pass the correct value, currency and transaction ID;
• phone conversions represent real calls rather than clicks alone;
• cross-domain journeys retain attribution;
• consent choices are respected; and
• GCLID, GBRAID and WBRAID identifiers are retained where relevant.

Reconcile the test across the website, Google Ads and the CRM or ecommerce platform. Tag Assistant and Google Ads diagnostics can confirm implementation, but the destination system confirms whether a genuine business record was created.

Review Enhanced Conversions

Enhanced conversions use hashed first-party customer data to improve conversion matching. Check whether the appropriate version is enabled, whether useful customer data is being supplied and whether diagnostics show a problem.

Lead-generation accounts should assess Enhanced Conversions for Leads alongside click identifiers and CRM data. It improves the connection between a website enquiry and a later offline outcome; it does not remove the need for a consistent sales pipeline.

Our guide to enhanced conversion tracking covers the implementation choices.

Audit Offline Conversion Tracking

Online conversion tracking records actions such as a website form, purchase or telephone call. Offline conversion tracking sends later outcomes from another system back to Google Ads.

For a service business, the journey may be:

Google Ads click → Website enquiry → Qualified Lead → Sales Opportunity → Closed Won → Revenue

If Google receives only the website enquiry, Target CPA can optimise for people likely to submit forms. It cannot know that one campaign generated valuable customers while another generated cheap but unsuitable leads.

An audit should therefore ask:

• Does the CRM retain advertising identifiers and first-party data?
• Are lifecycle stages defined consistently?
• Which stages have enough volume and quality to import?
• Are events sent once, with the correct time, value and currency?
• Can results be reported by campaign, keyword, search term and landing page?
• Is bidding focused on the initial lead, a qualified stage or actual revenue?

Offline tracking is particularly valuable for lead generation because it turns the audit from a cost-per-form review into a commercial analysis. Our offline conversion tracking guide and CRM integration guide explain this process in more detail.

Audit Account-Level Settings and Integrations

Once measurement is understood, review the controls that affect the entire account.

Google’s recommendations can provide useful prompts, but they are not an independent audit. The optimisation score changes when recommendations are applied or dismissed. It does not validate profitability, lead quality, tracking accuracy or whether broader targeting suits the business.

Recommendations to increase budgets, use Broad Match, remove keywords or enable more automation should be assessed against account evidence—not adopted to raise a score.

Audit Campaign Types and Their Roles

Each active campaign should have a defined job within the strategy.

The answer is not that every account should use every campaign type. A focused Search account can be correct for a business with limited budget and strong bottom-of-funnel demand. Performance Max can be highly effective when tracking, creative and conversion volume are strong. The audit should judge suitability, not feature adoption.

See our guide to Google Ads campaign types and targeting options for a wider comparison.

Audit Campaign Structure

Campaign structure determines where budgets, locations, goals, bidding strategies and reporting can be controlled separately.

Separate campaigns when there is a valid commercial reason, such as:

• different products or services;
• different geographic markets;
• different margins or conversion values;
• separate sales teams;
• different conversion goals;
• brand versus non-brand demand;
• different schedules or networks; or
• a requirement for an independent budget or bidding target.

Avoid both extremes. Excessive fragmentation leaves campaigns and ad groups with too little data. Over-consolidation combines unrelated intentions and makes it difficult to control spend or match the correct advert and landing page.

At ad-group level, organise keywords around a shared search intention. A practical Single Theme Ad Group can contain closely related exact and phrase keywords served by the same advert and page. It does not need a separate ad group for every minor wording variation.

Our Google Ads account structure guide explains this approach.

Separate Brand and Non-Brand Performance

Brand searches usually have higher intent, lower costs and stronger conversion rates because the person already knows the organisation. Mixing them with generic acquisition can make prospecting look more efficient than it is.

Check whether:

• brand activity has an appropriate campaign and budget;
• brand bids and match types are controlled;
• generic campaigns exclude the advertiser’s name where required;
• competitors are bidding on the brand;
• Performance Max is receiving branded traffic; and
• reporting distinguishes captured existing demand from new-customer acquisition.

The objective is not to exclude brand universally. It is to understand its contribution and prevent it from obscuring the performance of non-brand growth.

Audit Campaign Settings

Campaign settings can quietly undermine an otherwise strong structure.

Review:

• campaign-specific conversion goals;
• Search and Display network settings;
• Search partners performance;
• locations and advanced location options;
• languages;
• start and end dates;
• advert schedules;
• budget type and allocation;
• bidding strategy and target;
• final URL expansion and page exclusions;
• automatically created assets; and
• brand controls and negative keywords.

Do not assume the selected marketing objective controls everything. Bidding strategy, conversion goals and targeting determine how the campaign actually behaves.

Likewise, a “Limited by budget” warning does not automatically justify more spending. If traffic is relevant and marginal conversions remain profitable, a higher budget may be appropriate. If the campaign is inefficient, adding budget allows it to waste money faster.

Audit Google Ads Bidding and AI

Google Ads now uses machine learning across bidding, matching, creative and campaign delivery. An audit must assess both the automation setting and the information used to train it.

The main bidding approaches include:

Smart Bidding works at auction time using contextual signals that manual adjustments cannot replicate. However, automation does not correct weak objectives. If every form submission is worth one conversion, Google will pursue form submissions. If qualified stages or revenue are imported reliably, it can optimise closer to business value.

As a practical One PPC benchmark rather than a Google rule, around 15 meaningful conversions per campaign each month may be a minimum starting point for testing Target CPA. We prefer 30–50 or more where possible. Value-based bidding generally benefits from more frequent and dependable value data, especially when conversion values vary widely.

The audit should consider:

• conversion volume and delay;
• the quality of the selected conversion actions;
• whether values reflect revenue, margin or a credible lead value;
• targets compared with historical performance;
• frequent target changes;
• campaigns constrained by budget;
• learning periods and recent structural changes;
• tracking outages or contaminated data; and
• whether portfolio bidding combines campaigns with compatible economics.

Read our Google Ads bidding strategy guide and value-based bidding guide for more detail.

Audit Keywords and Search Intent

Keywords remain a central Search targeting control, but they should not be reviewed in isolation. One keyword can match many searches, and Google also uses meaning, context and other signals to determine eligibility.

Start by mapping the keyword coverage against the products, services, locations and stages of demand the business wants to reach.

Look for:

• important commercial themes that are missing;
• short, ambiguous keywords consuming disproportionate spend;
• several ad groups competing for the same search;
• keywords leading to the wrong advert or landing page;
• low-volume duplication that adds complexity without control;
• product or service themes with different commercial values; and
• informational searches being treated like bottom-of-funnel demand.

The One PPC keyword research guide covers intent, selection and organisation in more detail.

Review Keyword Match Types

Exact, phrase and Broad Match offer different balances of reach and control. Exact Match is not literally exact, and Phrase Match can interpret meaning beyond the precise wording. Broad Match provides the greatest expansion and relies heavily on Google’s understanding of intent and conversion data.

For many lead-generation accounts, exact and phrase provide a sensible foundation. Broad Match may scale successfully when:

• conversion tracking is accurate;
• the account has sufficient meaningful conversions;
• Smart Bidding is optimising towards a valuable outcome;
• negative-keyword management is strong; and
• the budget can support exploration.

It is riskier when conversion volume is low, the account counts weak actions, lead quality is unknown or the business serves a narrow market.

Review the Google Ads keyword match-type guide before deciding how much reach to allow.

Audit AI Max for Search

AI Max is a collection of optional Search campaign features rather than a separate campaign type. It can expand matching beyond the added keywords, adapt advert text and select more relevant landing pages.

This means its audit cannot stop at whether the switch is on. Review:

• the additional queries it reaches;
• whether the correct service and location pages are selected;
• lead or sales quality from expanded traffic;
• brand and URL controls;
• text customisation accuracy;
• incremental conversions rather than total claimed conversions; and
• whether restrictive campaigns should remain under tighter control.

AI Max may help capture useful long-tail demand, but it should not replace clear campaign themes, reliable conversion data or search-term analysis. See our practical guide to Google Ads AI Max.

Audit the Search Terms Report

The keyword table shows what the advertiser selected. The Search Terms report shows what people actually searched before the advert appeared.

Classify material search expenditure into:

• high-intent commercial searches;
• relevant consideration or research searches;
• existing-customer and navigational searches;
• competitor terms;
• employment, training and qualification searches;
• free, DIY or informational searches;
• irrelevant meanings and adjacent industries;
• locations outside the service area; and
• patterns associated with spam or weak leads.

Do not judge relevance solely from the phrase. Compare converting search terms with CRM or ecommerce outcomes. A term with a low front-end CPA may produce poor sales, while a more expensive term may generate a much higher qualification and close rate.

Quantify waste where possible. “Add negative keywords” is generic. “Exclude the employment and training themes responsible for £1,800 of non-converting spend” gives the business a clear reason to act.

Use our Search Terms report guide for a detailed review process.

Audit Negative Keywords

Negative keywords prevent unsuitable searches from using budget, but an audit must check both missing exclusions and accidental over-blocking.

Review negatives at:

• account level;
• shared-list level;
• campaign level; and
• ad-group level.

Account and shared lists are useful for themes that are irrelevant everywhere. Campaign negatives can separate services, locations or campaign roles. Ad-group negatives can help the correct query reach the most appropriate advert and landing page.

Single-word negatives can simplify broad irrelevant themes, but they need careful review because one word may appear inside a valuable search. Negative keywords also do not automatically cover every close variant, singular, plural or synonym.

Our negative keyword guide explains match types and implementation, while the negative keyword list provides research ideas that should be adapted to the individual business.

Audit Adverts and Ad Assets

An advert should do more than win a click. It should match the search, communicate why the business is suitable and discourage clearly unsuitable prospects where possible.

Review responsive search adverts for:

• alignment with the ad group’s intent;
• a clear product, service and location;
• a credible value proposition;
• benefits rather than generic claims;
• useful proof such as reviews, experience, accreditations or guarantees;
• prices or qualifying criteria where commercially appropriate;
• a strong call to action;
• accurate, policy-compliant claims;
• genuinely distinct headlines and descriptions; and
• a final URL that fulfils the promise in the advert.

Avoid judging copy from click-through rate alone. An advert that attracts everybody may produce more clicks but worse leads. Evaluate CTR alongside conversion rate, qualified-lead rate, CPA, customer acquisition cost and revenue.

Ad Strength can identify limited variation or missing components, but it is not a profitability score. Do not weaken a precise commercial message merely to satisfy a construction prompt.

Review Every Relevant Asset

Check whether the account uses suitable:

• business-name and logo assets;
• sitelinks;
• callouts;
• structured snippets;
• image assets;
• call assets;
• location assets;
• price and promotion assets; and
• lead-form assets where appropriate.

Remove outdated offers, weak stock imagery, obsolete telephone numbers and sitelinks that send paid traffic to irrelevant pages. Assets should add useful information, not repeat the same generic message in more space.

Audit Landing Pages and the Post-Click Journey

Google Ads can deliver a relevant visitor, but the landing page determines whether that opportunity becomes a lead or sale.

Review the page on mobile and desktop for:

• a close match between the search, advert and page headline;
• a clear value proposition above the fold;
• a visible and appropriate call to action;
• useful service or product information;
• reviews, credentials and trust signals;
• form length and question relevance;
• page speed and usability;
• clear telephone and live-chat options;
• accurate price, availability and location information;
• working links and forms;
• privacy and consent information;
• confirmation-page behaviour; and
• preservation of UTMs and advertising click identifiers through redirects.

Segment conversion rate by landing page, campaign, theme and device. A poor account average may be caused by one high-spend page or a mobile form problem rather than the whole website.

For lead generation, compare submission volume with lead quality. Removing every form field may increase conversion rate while increasing spam and unqualified enquiries. The strongest landing page creates the best commercial balance between volume, quality and sales—not necessarily the greatest number of form submissions.

Audit Locations, Devices, Schedules and Audiences

Locations

Confirm both the selected areas and the advanced location option. Google can target people based on presence or interest, depending on the setting. Many local service businesses require presence-based targeting to reduce enquiries from outside the service area, while travel, property and other sectors may legitimately need location interest.

Use location reports to identify:

• spend outside operational areas;
• regions with different conversion or sales rates;
• strong locations constrained by a shared budget;
• weak postcode clusters; and
• areas that need their own advert or landing page.

Devices

Compare mobile, desktop and tablet performance using downstream business outcomes as well as online conversions. Poor mobile results may reveal a slow page, difficult form or unanswered telephone calls rather than weak mobile demand.

Automated bidding can adjust bids using device signals, but the audit must still identify experience and operational problems that bidding cannot fix.

Ad Schedules

Review performance by day and hour while allowing for conversion delay and sample size. Telephone-led companies should compare advert schedules with answer rates and sales-team availability.

Do not exclude a time period because of a few expensive clicks. Look for sustained evidence and consider whether the actual issue is poor call handling or slow follow-up.

Audiences and Customer Data

Review audience segments in Observation and Targeting modes. Observation provides reporting without restricting eligibility; Targeting narrows who can see the campaign.

Check remarketing lists, Customer Match, conversion-based customer lists and GA4 audiences. First-party data can support bidding, exclusions, remarketing and customer acquisition, but it must be collected and used with appropriate consent and policy compliance.

Audit Performance Max Properly

Performance Max should be reviewed as part of the whole account, not judged from its headline ROAS or CPA alone.

Assess:

• its intended role;
• brand and non-brand contribution;
• new versus returning customers;
• Search terms and search-category insights;
• channel and placement reporting where available;
• asset-group themes;
• audience signals;
• creative coverage and quality;
• final URL expansion and page exclusions;
• automatically created assets;
• campaign and account negatives;
• brand exclusions;
• location performance;
• conversion goals and values; and
• product-feed segmentation for retail.

A Performance Max campaign can legitimately outperform standard Search because it has wider inventory, more signals and more flexibility. It can also look stronger because it captures branded demand, remarketing users or conversions another campaign would otherwise have received.

The audit should therefore ask whether it adds profitable reach. For lead generation, compare lead quality by campaign rather than relying only on reported cost per conversion. Our guide to Performance Max for lead generation covers the main risks and opportunities.

Audit Shopping, Demand Gen, Display and Video

Shopping

For Shopping and retail Performance Max, review Merchant Center diagnostics, disapprovals, titles, descriptions, GTINs, categories, images, prices, availability and shipping information.

Analyse results by item ID, product type, brand, stock status, margin and return rate. The product feed is a targeting and merchandising system, not just an administrative upload.

Demand Gen, Display and Video

Review audience strategy, placements, content suitability, creative formats, frequency and the role of view-through conversions. Separate prospecting from remarketing so existing visitors do not make new-customer acquisition look stronger.

Judge each campaign against its intended purpose. An awareness campaign should not be evaluated like an exact-match Search campaign, but “awareness” should still have defined measures and a clear contribution to the wider strategy.

Use Quality Score as a Diagnostic

Quality Score is based on expected click-through rate, advert relevance and landing-page experience. Google describes it as a diagnostic tool, not a key performance indicator or an exact representation of the auction calculation.

Use it to identify alignment problems:

• Below-average expected CTR may indicate weak or uncompetitive messaging.
• Below-average advert relevance may indicate an ad group contains several different intentions.
• Below-average landing-page experience may indicate poor message match, usefulness or usability.

Do not restructure a profitable account simply to chase a higher score. The business objective remains qualified leads, customers, revenue and profit. Our Quality Score guide explores these components in detail, while Google’s official Quality Score guidance confirms its diagnostic role.

Use Impression Share to Find Constraints

Impression share helps determine whether campaigns are capturing the available searches for which they are eligible.

Review:

• Search Impression Share;
• Search Lost Impression Share due to budget;
• Search Lost Impression Share due to rank;
• Search Top Impression Share; and
• Search Absolute Top Impression Share.

These metrics can show whether growth is constrained by budget, Ad Rank or targeting. However, low impression share is not automatically a problem. The campaign may deliberately participate only where it expects to meet a strict profitability target.

The objective is profitable impression share: strong visibility for valuable searches without paying a disproportionate premium for traffic that does not generate business outcomes. Read our Google Search Impression Share guide for the distinction between share, top rate and absolute-top metrics.

Turn Findings Into Priorities

The audit should finish with a short summary that a decision-maker can understand quickly. Group findings by commercial impact rather than repeating the order of the Google Ads menus.

Critical: Fix Immediately

Typical examples include:

• broken or duplicated Primary conversions;
• automated bidding using meaningless actions;
• campaigns serving outside the business area;
• compromised or unnecessary administrator access;
• broken landing pages;
• serious policy or billing risks; and
• incorrect purchase values or currencies.

High Impact: Implement Next

Typical examples include:

• substantial irrelevant search expenditure;
• budget being diverted from proven demand;
• poor campaign-to-landing-page alignment;
• missing Qualified Lead, customer or revenue feedback;
• unsuitable bidding targets;
• excessive brand reliance; and
• weak high-traffic landing pages.

Test and Develop

Typical examples include:

• new advert propositions;
• carefully controlled Broad Match or AI Max expansion;
• new audiences;
• remarketing;
• Performance Max expansion;
• creative improvements; and
• landing-page experiments.

For every recommendation, state:

This turns an audit from a list of opinions into an implementation document.

Implement Audit Recommendations in the Correct Order

Do not change tracking, structure, bidding, adverts and landing pages simultaneously. If everything changes at once, it becomes difficult to identify what improved or damaged performance.

A safer implementation order is:

1. Fix critical access, policy and tracking problems.
2. Remove obvious irrelevant traffic and repair broken journeys.
3. Align conversion goals and values with business outcomes.
4. Correct campaign structure, location targeting and budget allocation.
5. Adjust bidding after the measurement foundation is dependable.
6. Test new adverts, assets, targeting and landing pages.
7. Monitor Google Ads results alongside CRM, sales and revenue outcomes.

Document every major change, allow for conversion lag and agree the success measure before the test begins. A recommendation is not proven until the result is measured.

Google Ads Audit Checklist

Use this shorter checklist to make sure the audit covers the essential areas:

• Confirm business objectives, margins, targets and sales capacity.
• Select representative comparison periods and allow for seasonality.
• Review change history before diagnosing movements.
• Inventory and test every conversion action.
• Reconcile Google Ads conversions with the website, CRM or ecommerce platform.
• Correct Primary, Secondary, account-default and campaign-specific goals.
• Review values, currencies, count settings and duplicate prevention.
• Check enhanced conversions and offline conversion tracking.
• Review user access, billing and linked accounts.
• Inspect auto-apply settings, scripts, rules and third-party tools.
• Confirm that each campaign has a defined strategic role.
• Separate brand and non-brand results where appropriate.
• Assess whether campaign structure supports budget and goal control.
• Review networks, locations, location options and schedules.
• Analyse keywords, match types and actual search terms.
• Add or consolidate negative keywords without over-blocking.
• Review AI Max expansion and URL selection where enabled.
• Assess responsive search adverts and every relevant asset.
• Test landing pages on mobile and desktop.
• Match the bidding strategy to the goal, data volume and measurement quality.
• Reallocate budget according to commercial performance.
• Review devices, audiences and first-party data.
• Audit Performance Max brand contribution, queries, assets and URLs.
• Check Merchant Center feed quality for retail campaigns.
• Review placement, frequency and view-through reporting for visual campaigns.
• Use Quality Score and impression share as diagnostics.
• Prioritise every finding by impact, evidence, urgency and effort.
• Implement changes in stages and measure the downstream result.

How Often Should a Google Ads Account Be Audited?

Most established accounts benefit from a formal audit at least quarterly, supported by weekly and monthly optimisation. Higher-spend accounts, new implementations and rapidly changing businesses may need more frequent reviews.

Undertake an additional audit when:

• performance changes unexpectedly;
• the website, checkout or conversion tracking is replaced;
• a CRM or ecommerce platform is introduced;
• management changes hands;
• the business adopts AI Max, Performance Max or another major campaign change;
• new products, services or locations are launched;
• lead volume increases while sales quality falls; or
• budgets increase materially.

Between formal reviews, use a repeatable Google Ads optimisation checklist to monitor search terms, budgets, tracking, adverts and commercial results.

Frequently Asked Questions

Can I Audit My Own Google Ads Account?

Yes. A business owner or internal marketer often understands margins, lead quality and sales capacity better than an external reviewer. That context can uncover problems that are invisible inside Google Ads.

An independent specialist can still add value by challenging familiar structures, checking advanced settings and separating genuine best practice from account habits that have never been tested.

Is Google’s Optimisation Score an Audit?

No. It is Google’s estimate of how selected recommendations may improve campaign performance. It does not independently validate conversion accuracy, lead quality, profitability, CRM outcomes or whether expansion aligns with the business strategy.

Should Every Google Ads Recommendation Be Applied?

No. Review each recommendation against the account’s objective, measurement quality and evidence. Suggestions to broaden targeting or increase budgets may be useful, but they can also increase waste when the conversion signal is weak.

What Is the Most Important Part of an Audit?

Conversion measurement is usually the first foundation because it determines whether reported performance and automated bidding can be trusted. Targeting and landing-page quality are equally important to the final result, but they cannot be judged properly when the outcome is measured incorrectly.

Should an Audit Recommend Broad Match and Automation?

Only when the account can support them. Broad Match, AI Max, Performance Max and Smart Bidding can expand results, but they require accurate conversion signals, suitable volume, adequate budget and ongoing search-quality analysis. For many lead-generation accounts, exact and phrase match remain the safer starting point.

Should Changes Be Made During the Audit?

Critical problems may need immediate action, particularly broken tracking, policy risks or substantial irrelevant spend. Other recommendations should be prioritised and introduced in a controlled sequence so their impact can be measured.

Turn the Google Ads Audit Into a Growth Plan

The value of an audit is not the number of faults it finds. Its value is the quality of the decisions it enables.

A strong audit identifies what is already working, isolates the constraints that matter and connects Google Ads activity with qualified leads, customers, revenue and profit. It then translates those findings into a practical order of work.

If you would like an independent assessment, explore our Google Ads audit service. One PPC can review your tracking, campaign structure, search terms, bidding, adverts, landing pages and CRM feedback, then produce a prioritised plan to reduce waste, increase conversions and improve commercial results.
