Why Regular Google Ads Audits Matter

Conducting a google ads account audit is essential for maintaining campaign efficiency and maximising return on investment. Without regular reviews, accounts accumulate inefficiencies, wasted spend, and missed opportunities that can drain budgets and diminish performance over time.

An effective audit identifies underperforming keywords, reveals structural issues, uncovers tracking problems, and highlights optimisation opportunities that can significantly improve your results. Whether you manage a small local campaign or an enterprise-level account, a systematic review process helps you understand where your money is going and how to get better results.

Most successful advertisers conduct comprehensive audits quarterly, with lighter monthly reviews to catch issues early. This cadence ensures you stay on top of algorithm changes, competitive shifts, and seasonal variations whilst maintaining optimal account health.

Preparing for Your Google Ads Account Audit

Proper preparation streamlines the audit process and ensures you don’t miss critical areas. Start by gathering the tools and access credentials you’ll need throughout your review.

When you’re ready to begin, start with high-level account settings before drilling down into campaign-specific details. This top-down approach ensures you don’t miss fundamental issues that affect the entire account.

Audit Your Account Structure and Campaign Organisation

Account structure forms the foundation of effective campaign management. A well-organised account enables better budget control, more precise targeting, and easier optimisation. When you audit google ads campaign structure, evaluate whether the organisation supports your business goals.

Examine how campaigns are segmented. Best practice involves separating campaigns by:

• Product or service category
• Geographic targeting requirements
• Campaign objective (brand awareness vs. conversions)
• Budget allocation needs
• Audience intent levels (branded vs. generic keywords)

Within campaigns, review ad group organisation. Each ad group should contain tightly themed keywords (typically 5-20) that relate to specific products, services, or search intents. Overly broad ad groups dilute ad relevance and reduce Quality Score.

Check for campaign duplication and keyword overlap between ad groups. Use the Auction Insights and Search Terms reports to identify situations where your own campaigns compete against each other, inflating costs unnecessarily.

Verify Conversion Tracking and Measurement

Accurate conversion tracking is absolutely critical for a meaningful google ads account audit. Without reliable data, you cannot make informed optimisation decisions or calculate true return on ad spend. This section often reveals the most costly issues.

Start by reviewing all conversion actions defined in your account. Navigate to Tools & Settings > Measurement > Conversions and verify:

• All important business actions are tracked (purchases, leads, phone calls, sign-ups)
• Conversion values accurately reflect business value
• Attribution models align with your customer journey
• Conversion counting settings (every conversion vs. one per click) are appropriate
• Tags are firing correctly using Google Tag Assistant or preview mode

Test each conversion action by completing the action yourself and verifying it appears in your conversion reports within 24-48 hours. This practical verification catches implementation errors that technical checks might miss.

Cross-reference Google Ads conversion data with your actual business records. Significant discrepancies indicate tracking issues, duplicate counting, or test conversions polluting your data. For e-commerce businesses, compare Google Ads reported revenue against your shopping cart analytics.

If tracking issues emerge, consider implementing or reviewing your GTM setup service configuration to ensure robust, maintainable measurement infrastructure.

Analyse Keyword Performance and Search Terms

Keyword analysis forms the core of how to audit ppc account performance effectively. This section identifies which search terms drive valuable traffic versus those wasting budget on unqualified clicks.

Begin with the Search Terms report (found under Keywords > Search Terms). This shows the actual queries triggering your ads, revealing:

• Irrelevant searches from broad or phrase match keywords
• High-performing search terms you should add as exact match keywords
• Negative keyword opportunities to exclude wasteful traffic
• Search intent mismatches between keywords and your offerings

Examine keyword-level metrics including Quality Score, impression share, and average position. Keywords with Quality Scores below 5 indicate poor relevance between keywords, ad copy, and landing pages, resulting in higher costs per click.

For established accounts, identify “zombie keywords”—those with thousands of impressions but minimal clicks or conversions. These typically indicate mismatched search intent and should be paused or moved to separate testing campaigns with appropriate negative keywords.

Review Ad Copy, Extensions, and Quality Score

Your ad creatives directly influence click-through rate, Quality Score, and ultimately your cost per conversion. A thorough google ads review checklist must evaluate both ad effectiveness and technical setup.

Review all active ads for each ad group, checking for:

• Keyword inclusion in headlines and descriptions
• Unique selling propositions and competitive differentiators
• Clear calls-to-action that match landing page offers
• Use of all available headline and description fields
• Ad strength ratings (aim for “Excellent” in responsive search ads)
• Sufficient variation testing (minimum 3 ads per ad group)

Responsive search ads (RSAs) now dominate Google Ads, having replaced expanded text ads. Ensure your RSAs include diverse headlines and descriptions that cover different value propositions, keyword variations, and calls-to-action. Google’s machine learning performs best with varied creative input.

Verify you’ve implemented appropriate extensions for your business:

• Sitelink extensions (minimum 4-6 per campaign)
• Callout extensions highlighting key benefits
• Structured snippets for service/product categories
• Call extensions with tracked phone numbers
• Location extensions for businesses with physical premises
• Price extensions for transparent pricing models
• Promotion extensions for current offers
• Image extensions to enhance visual appeal

Review extension performance in the Extensions report to identify underperformers. Rotate extension messaging regularly to test different value propositions and maintain freshness, particularly for seasonal businesses.

Navigate to the Keywords tab and add the Quality Score columns to identify improvement opportunities. Focus optimisation efforts on high-spend keywords with Quality Scores of 6 or below, as improving these delivers the greatest cost reduction impact.

Assess Budget Allocation and Bidding Strategies

Budget and bidding strategy significantly impact campaign performance and efficiency. When you audit google ads campaign spending patterns, you’ll often discover misallocated budgets limiting your best performers whilst overinvesting in underperformers.

Review campaign-level budgets against actual performance. Campaigns frequently hitting budget limits (90%+ of days) likely suffer from constrained delivery, missing valuable impression opportunities. Conversely, campaigns spending only 40-60% of budget indicate low search volume or overly restrictive targeting.

Analyse spend distribution across campaigns relative to their conversion contribution. A common issue is equal budget allocation across unequal performers. Your budget distribution should reflect performance, allocating more to campaigns delivering better return on ad spend.

Evaluate bidding strategies for appropriateness:

• Manual CPC: Provides maximum control but requires active management—appropriate for new campaigns or when testing
• Maximise Clicks: Drives traffic within budget but ignores conversion quality—use cautiously
• Target CPA: Optimises for conversions at specified cost—requires conversion tracking and sufficient data (30+ conversions monthly)
• Target ROAS: Optimises for revenue efficiency—best for e-commerce with accurate conversion values
• Maximise Conversions: Spends full budget optimising for conversion volume—monitor closely for efficiency
• Maximise Conversion Value: Prioritises high-value conversions—requires accurate conversion value tracking

Smart Bidding strategies (Target CPA, Target ROAS, Maximise Conversions) require sufficient conversion volume to function effectively. As a guideline, campaigns should generate at least 30 conversions monthly for Target CPA and 50 for Target ROAS. Below these thresholds, consider manual bidding or portfolio strategies combining multiple campaigns.

Check the Recommendations tab for budget and bidding suggestions, but evaluate each critically. Google’s recommendations prioritise spending increases, which may not align with your efficiency goals.

Evaluate Targeting Settings and Audience Performance

Targeting settings determine who sees your ads, making them crucial elements of any google ads account audit. Misconfigured targeting can exclude valuable audiences or waste budget on irrelevant users.

Start with geographic targeting. Review location settings at the campaign level and verify you’re targeting the correct regions. Check the “Location options” advanced setting—”Presence or interest” is default but often too broad, showing ads to people interested in your location but physically elsewhere. For most local businesses, “Presence: People in or regularly in your targeted locations” produces better results.

Examine the Locations report under campaign settings to see where your ads actually appear. You may discover significant spend in untargeted locations, indicating your settings need tightening or that location bid adjustments are necessary.

For Search campaigns, review whether you’re using observation-only audiences versus targeting audiences. Observation mode allows you to gather performance data without restricting reach, typically the better starting approach. Reserve targeting mode for situations where you specifically want to limit who can see your ads.

Examine network settings. Search campaigns should generally exclude Search Partners unless specifically tested, as partner quality varies significantly. Similarly, Display campaigns including “All eligible sites” should be monitored carefully using placement exclusions to block poor performers.

Common Issues and Quick Fixes

During your google ads account audit, you’ll likely encounter recurring issues. This troubleshooting guide addresses the most common problems and their solutions.

Document all identified issues with severity ratings (critical, high, medium, low) and estimated impact. Prioritise fixes that address critical tracking issues first, followed by high-impact optimisations that improve efficiency on high-spend elements.

Create a phased implementation plan rather than changing everything simultaneously. This approach allows you to measure the impact of specific changes and avoid destabilising account performance with too many concurrent modifications.
