A Google Ads audit is a systematic review of an advertising account to identify inefficiencies, misconfigurations, and missed opportunities. Done thoroughly, an audit can uncover thousands of dollars in wasted spend that routine optimization overlooks.
The difference between an audit and regular account management is scope. Day-to-day optimization focuses on incremental improvements: adjusting bids, pausing underperformers, testing ad copy. An audit steps back and evaluates whether the entire account is structured and configured to succeed.
This guide provides a comprehensive checklist that agencies and advertisers can follow to audit any Google Ads account from top to bottom.
When to Conduct a Google Ads Audit
Not every account needs an audit every month, but certain situations make one essential.
Onboarding a new client. Before making changes to an account you did not build, an audit establishes a baseline and identifies quick wins that build early credibility.
Performance plateau or decline. When incremental optimization stops moving the needle, structural issues may be the root cause. An audit can surface problems that bid adjustments alone cannot fix.
Before scaling spend. Increasing budget in a poorly structured account amplifies waste. Audit first to ensure the foundation supports higher spend levels.
Periodically as preventive maintenance. Even well-managed accounts accumulate inefficiencies over time. A quarterly or semi-annual audit keeps accounts clean and aligned with current best practices.
The Google Ads Audit Checklist
Work through each section in order. Document your findings as you go, noting both issues and their estimated impact so you can prioritize fixes.
1. Account Structure
Account structure determines how effectively you can manage bids, budgets, and targeting. Poor structure creates cascading problems that affect everything downstream.
Campaign organization. Are campaigns organized by theme, product line, match type, geography, or funnel stage? There is no single correct structure, but the chosen approach should be consistent and logical. Look for catch-all campaigns that combine unrelated products or services.
Ad group granularity. Each ad group should contain tightly related keywords that can be served by the same set of ads. Ad groups with more than 15-20 keywords usually indicate insufficient segmentation. Check whether ad group themes are distinct or overlapping.
Naming conventions. Consistent naming makes accounts manageable at scale. Look for inconsistent capitalization, abbreviations, or naming patterns that make it hard to understand what each campaign or ad group targets.
Campaign type alignment. Verify that Search, Display, Shopping, Video, and Performance Max campaigns are separated appropriately. Blended campaign types make performance analysis and optimization difficult.
2. Campaign Settings
Settings errors are among the most expensive mistakes in Google Ads because they silently waste money without surfacing obvious performance issues.
Network settings. Check whether Search campaigns include Search Partners and Display Network opt-ins. Many advertisers unknowingly serve ads on the Display Network through Search campaigns, which typically produces lower-quality traffic at higher cost.
Location targeting. Verify that location targeting uses "Presence: People in or regularly in your targeted locations" rather than the default "Presence or interest," which shows ads to people who search about your locations but may live elsewhere.
Language settings. Confirm languages match your target audience. Overly broad language targeting can serve ads to users who cannot read them.
Bid strategy alignment. Is the bid strategy appropriate for the campaign's goals and data volume? Automated bidding strategies need sufficient conversion data to work effectively. Campaigns with fewer than 30 conversions per month may perform better with manual or enhanced CPC bidding.
Ad rotation. Check whether ad rotation is set to "Optimize" (Google selects the best-performing ad) or "Do not optimize" (ads rotate evenly). For active testing, even rotation is preferred. For set-and-forget campaigns, optimization makes sense.
Budget allocation. Are budgets distributed according to performance potential? Look for high-performing campaigns that are budget-constrained while low-performing campaigns have excess budget. Check for shared budgets that may cause high-priority campaigns to compete with low-priority ones for the same pool.
3. Keyword Analysis
Keywords are the targeting foundation of Search campaigns. Keyword issues are among the most common findings in Google Ads audits.
Match type distribution. Review the balance between broad, phrase, and exact match keywords. Over-reliance on broad match without proper negative keywords leads to irrelevant traffic. Conversely, using only exact match can limit reach unnecessarily.
Search term analysis. Pull the search terms report for the past 90 days. Look for irrelevant queries that triggered your ads, high-spend queries with no conversions, and valuable queries that should be added as keywords.
Negative keyword coverage. Evaluate the negative keyword lists for completeness. Are there obvious irrelevant terms missing? Are negatives applied at the appropriate level (campaign vs. ad group)? Check for conflicts where negative keywords block valuable traffic.
Keyword overlap and cannibalization. Identify cases where the same keyword appears in multiple ad groups or campaigns. Overlap forces your ads to compete against each other and makes performance data unreliable.
Low Quality Score keywords. Filter for keywords with Quality Scores below 5. These keywords pay a premium per click and drag down overall account performance. For each low-QS keyword, determine whether the issue is ad relevance, landing page experience, or expected CTR.
Keyword to ad group ratio. Ad groups with too many keywords cannot serve highly relevant ads. Groups with too few keywords may not generate enough volume. Look for the balance point.
4. Ad Copy and Creative
Ads are what users actually see. Weak ad copy wastes every dollar spent getting the click.
Ad count per ad group. Each ad group should have at least 2-3 responsive search ads to enable testing and optimization. Ad groups with only one ad have no room for improvement through testing.
Headline and description utilization. Responsive search ads allow up to 15 headlines and 4 descriptions. Check whether ad groups are using the full allocation. Under-utilizing headline slots limits Google's ability to assemble high-performing combinations.
Keyword insertion and relevance. Do ads include the target keywords or close variants in headlines? High relevance between search query, keyword, ad copy, and landing page is the foundation of Quality Score.
Call-to-action clarity. Every ad should include a clear call to action. Vague ads that describe features without directing the user to take action typically underperform.
Ad strength indicator. Google provides an ad strength rating for responsive search ads. While not a perfect metric, ads rated "Poor" or "Average" are worth reviewing for improvement opportunities.
Pin usage. Check if headlines or descriptions are pinned to specific positions. Excessive pinning limits Google's optimization flexibility. Strategic pinning (like keeping your brand name in headline 1) is fine, but pinning everything defeats the purpose of responsive ads.
5. Ad Extensions (Assets)
Extensions increase ad real estate, improve CTR, and provide additional information to users. Missing extensions are free performance left on the table.
Sitelink extensions. Every account should have sitelinks pointing to relevant pages. Check that sitelinks are active, their URLs work, and the descriptions are populated.
Callout extensions. These short text snippets highlight key selling points. Verify they are present and relevant to current offerings.
Structured snippet extensions. These list specific aspects of your products or services. Check for relevance and completeness.
Call extensions. For businesses that accept phone calls, call extensions should be active during business hours with correct phone numbers.
Location extensions. For businesses with physical locations, confirm location extensions are linked and accurate.
Image extensions. Relatively newer, image extensions can significantly improve CTR. Check whether they are set up and approved.
Review extension performance data to identify underperformers that should be replaced.
6. Conversion Tracking
Without accurate conversion tracking, every other optimization decision is based on incomplete data. This section of the audit is arguably the most important.
Conversion actions. List all conversion actions configured in the account. Verify that each one is still relevant and firing correctly. Remove or reclassify outdated conversion actions.
Tag verification. Use Google Tag Assistant or Tag Manager to confirm that conversion tags fire on the correct pages, at the correct times, and only once per conversion event (unless counting "every" is intentional).
Attribution model. Check which attribution model is assigned to each conversion action. Last-click attribution is the default but may undervalue campaigns that drive awareness or consideration. Consider whether data-driven attribution is appropriate for accounts with sufficient conversion volume.
Conversion value tracking. For ecommerce accounts, verify that dynamic conversion values are passing correctly. For lead generation, check whether conversion values are assigned and reasonable.
Offline conversion imports. If the business has a sales cycle that extends beyond the initial form fill or call, offline conversion imports can dramatically improve bidding algorithm performance. Check whether this is set up or should be.
Cross-domain tracking. If the user journey crosses multiple domains (e.g., a main site to a booking platform), verify that tracking follows the user accurately.
7. Quality Score Analysis
Quality Score directly affects how much you pay per click and where your ads appear. A QS audit can reveal systemic issues.
Overall distribution. Calculate the weighted average Quality Score for the account using impression-weighted averages. Benchmark against 7/10 as a healthy target. Accounts averaging below 5/10 have significant room for improvement.
Component analysis. For each low-QS keyword, examine the three sub-components: Expected CTR, Ad Relevance, and Landing Page Experience. This tells you whether the fix is in the ad copy, the keyword grouping, or the landing page.
Landing page assessment. Visit the landing pages associated with low QS keywords. Check for relevance to the keyword, page speed, mobile usability, and clear conversion paths. A slow or irrelevant landing page undermines even the best ads.
8. Budget and Bid Analysis
Money allocation issues are where audits produce the most immediate financial impact.
Budget pacing. Check whether campaigns are regularly hitting their daily budgets. Campaigns that are limited by budget may be missing valuable conversions. Conversely, campaigns that never approach their budget may have too much allocated.
Wasted spend identification. Calculate total spend on keywords, search terms, and placements that produced zero conversions over the past 90 days. This "wasted spend" figure is often the most impactful finding in an audit.
Bid strategy performance. For automated bidding strategies, review the bid strategy report to check whether targets are being met. Look for strategies that have been in "learning" mode for too long or that consistently miss target CPA or ROAS.
Device bid adjustments. If manual bidding, check whether device bid adjustments reflect actual performance differences across desktop, mobile, and tablet.
Geographic performance. Review performance by location. Identify regions with poor ROI that may warrant bid reductions or exclusion.
Tools That Streamline Google Ads Audits
Manual audits are thorough but time-consuming. A complete audit following this checklist can take 4-8 hours for a medium-sized account. Several tools can accelerate the process.
Google Ads Scripts. Custom scripts can automatically check for common issues like broken URLs, budget-limited campaigns, low QS keywords, and missing extensions. Scripts are free but require JavaScript knowledge to write and maintain.
Google Ads Editor. The desktop application makes it faster to review bulk settings, filter for anomalies, and make batch changes based on audit findings.
Third-party audit tools. Platforms like AdsCockpit can automate significant portions of the audit process, running checks across all client accounts simultaneously and flagging issues with severity ratings. This transforms auditing from an occasional deep-dive into a continuous monitoring function.

Prioritizing Audit Findings
Not all issues are equally important. Use this framework to prioritize fixes:
High priority (fix immediately): Conversion tracking errors, network setting misconfigurations, location targeting mistakes, and budget allocation problems. These issues directly waste money or corrupt your data.
Medium priority (fix this week): Missing extensions, keyword overlap, inadequate negative keywords, and ad copy gaps. These issues reduce performance but are not actively destroying value.
Low priority (fix this month): Naming convention cleanup, ad group restructuring, and minor Quality Score improvements. These are important for long-term account health but do not have immediate financial impact.
Turning Audits Into Recurring Value
A one-time audit delivers a one-time benefit. Agencies that build audit processes into their ongoing workflow catch issues earlier and deliver consistently better results.
Schedule quarterly mini-audits that cover the highest-impact sections of this checklist. Use automation tools to monitor for the most common issues continuously. And always document your findings, both for client communication and for tracking whether fixes produced the expected improvements.
