In Summary
Learn what a thorough Google Ads audit should uncover, from wasted spend and tracking issues to campaign structure and conversion bottlenecks, and identify opportunities to improve performance.
Many businesses invest significantly in Google Ads yet still struggle to achieve consistent lead generation results. When performance fluctuates or cost per lead begins to rise, it can be difficult to identify exactly what’s causing the issue or explain the results to internal stakeholders.
When performance declines, a Google Ads audit is often the first step in understanding what has changed. However, many audits focus only on surface-level recommendations. A thorough audit goes much deeper, examining campaign structure, search intent, conversion tracking, bidding strategy and account history to uncover opportunities for improvement.
So, what should a thorough Google Ads audit look like? It must include these key elements.
Identify Sources of Wasted Spend
The purpose of a Google Ads audit is to identify inefficiencies that may be impacting campaign performance and return on investment. Performance issues are rarely caused by a single major problem. More often, several smaller issues combine to reduce efficiency over time.
A standard audit looks at your keywords, while a thorough audit looks at the Search Terms Report. Google has a loose interpretation of Close Variants, which means exact and phrase match keywords could trigger your ad in response to a completely irrelevant web search. A detailed review of the Search Terms Report can uncover search intent mismatches that may be impacting lead quality and campaign efficiency.
A thorough audit should also assess how branded traffic is being managed and whether campaign reporting accurately reflects incremental performance. Review network settings carefully to ensure campaign spend is being allocated appropriately across Search, Display and other placements based on your objectives. Check your location settings and ensure your ads are reaching consumers in your target location.
Campaign Structure and Performance
Campaign structure plays a significant role in Google’s ability to optimise effectively. This fragmentation can also limit the amount of meaningful conversion data available to each campaign, making optimisation more difficult. A thorough audit should also identify keyword overlap and internal competition between campaigns, which can sometimes increase costs without improving results.
A thorough audit should assess the following structural elements:
- Review campaign segmentation and negative keyword strategies to ensure traffic is being directed to the most relevant campaigns.
- Assess budget allocation and whether campaigns are receiving sufficient conversion volume to support automated bidding strategies.
- Review ad group structure to ensure keywords, ads and landing pages are closely aligned.
When Conversion Data Tells the Wrong Story
If lead volume or revenue remains lower than expected despite healthy click-through rates, the issue may lie within the conversion process itself. One of the most common issues uncovered during an audit is inaccurate conversion tracking. A thorough audit should include testing the entire conversion pipeline, from the initial click through to CRM reporting. Google Ads may report strong conversion activity while the CRM shows little evidence of qualified leads or sales. In some cases, low-value actions such as page views, button clicks or scroll depth may be configured as primary conversions. This can lead Google Ads to optimise for engagement rather than genuine business outcomes.
- Verify that your primary bidding goals are around high-value actions (qualified lead forms and purchases).
- It isn’t all about last-click attribution; top-of-funnel keywords deserve some credit as they start the customer on the journey.
- Review the landing page to make sure the copy aligns and it loads quickly with a simple-to-complete form.
A thorough audit should verify that conversion tracking reflects meaningful business outcomes and provides reliable data for optimisation.
Reviewing Account Management Practices
If you’re working with an agency or external account manager, an audit can also provide visibility into how the account is being managed and whether optimisation efforts align with business goals. While a good agency can deliver significant value, it’s important to understand how performance is being measured and whether optimisation efforts are aligned with your business objectives. The Google Ads Change History log can provide valuable insight into account activity and optimisation efforts over time, such as what changes have been made, when they occurred, and how actively the account is being managed.
Some useful areas to review include:
- Account Activity: Review account activity to understand how frequently campaigns are being optimised and whether meaningful changes are being made over time.
- Automation Settings: Review any automated recommendations or optimisation settings to ensure they align with your campaign objectives and overall strategy.
- Performance Metrics: Ensure reporting focuses on metrics that align with business outcomes, such as qualified leads, revenue, cost per acquisition and conversion rate, rather than awareness metrics alone
Next Steps
Google Ads performance requires ongoing monitoring, testing and optimisation. If results have been disappointing, the issue is rarely that Google Ads isn’t suitable for your industry. More commonly, performance challenges stem from tracking issues, search intent mismatches, inefficient budget allocation or campaign structure limitations.
A comprehensive audit should identify opportunities to improve efficiency, strengthen conversion tracking and create a clearer roadmap for future optimisation. An audit should highlight what you can stop today to save money and what should be restructured for better returns. Perhaps most importantly, an audit provides the visibility needed to make informed decisions and measure performance against meaningful business outcomes.
