What is a Google Ads audit?
A Google Ads audit is an evaluation of the performance of your Google Ads account. It reviews settings, structure, and data to find ways for improvement and optimization.
The secret to a good audit is to:
- Figure out what you want to check and why it’s important.
- Look at and write down the current state of each thing in the audit.
- Take careful notes and highlight examples of things that should be looked at or fixed in the action plan after the audit.
In the long run, this can reduce costs while increasing your return on investment (ROI).
In this article, Mega Digital will guide you through every corner of the audit process and ensure you follow the best accounting practices and spend money effectively.
Google Ads account audit benefits
Regular Google Ads audits help uncover wasted spend, improve performance, and identify opportunities for more effective account management.
Reduce wasted ad spend
An audit reveals ineffective keywords, irrelevant search terms, weak ads, and inefficient campaign settings. Addressing these issues allows you to redirect your budget toward campaigns that deliver stronger results.
Identify new opportunities
Reviewing account data can uncover valuable keywords, audiences, locations, devices, or campaign types that may have been overlooked. These insights can support new revenue and growth opportunities.
Improve campaign performance
Auditing your targeting, bidding, conversion tracking, and creative assets helps identify changes that can improve conversion volume, CPA, and ROAS.
According to Google Ads data on omnichannel Smart Bidding, advertisers using Smart Bidding with store conversions achieved an average 15% increase in omnichannel ROAS at a similar cost.
Optimize account management
An audit can highlight repetitive manual tasks and areas where automation may improve efficiency. It also helps simplify campaign structures and make ongoing account management easier.
Uncover actionable insights
Reviewing the entire account provides a clearer view of how campaigns work together. Even small findings, such as an underperforming device, location, or search term—can lead to meaningful performance improvements.
Google Ads account audit checklist
1. Set intentions
Before starting an audit, you should know where you are headed. Understanding your objectives and the types of campaigns you want to run can make the evaluation process go more smoothly. The key to an effective audit is:
- Decide what you’ll be reviewing and appreciate its significance.
- Examine and note the status of each audit item.
- Write thorough notes and highlight instances of things that the post-audit action plan needs to revisit or address.
Identify your key performance indicators (KPIs), such as conversion rate or cost-per-click. After that, assess your account’s performance against those goals.
2. Review performance trends
It is critical to have an overview of your trend lines and understand how performance has changed over time. By doing this, you will be able to identify the dropping point of your ads, analyze the causes of their decline, and investigate deeper, highlighting areas negatively affecting your PPC performance.
Reviewing your performance within a certain period—not too close (a few days, a few weeks) nor waiting for too long (more than 3 months). The right amount of time is 30-60 days to look at the fluctuation and make the right-timing adjustment.
After examining your goal and data, it’s time to dig deeper into the account’s structure and identify areas for improvement. Follow our guide to ensure you use a logical structure that aligns with your advertising goals and gain actual conversions.
3. Review Google Ads account’s organization
Organize all your accounts logically in some way that makes it simple to allocate your budget and maintain control of things.
Campaign settings
For a Google Ads campaign audit, here are some of the important settings:
- Ensure that Display and Search campaigns are not running at the same time.
- Set up device targeting properly.
- Assure to set up a location for your audience exactly how you want them. And whether your product suits the chosen area’s demographic.
- Make sure that you only advertise in the language your adverts are written.
- Check the exact and realistic budget amount for each campaign. See if any effective campaigns are running low on funds or have a lot of money to reallocate.
Ad group settings
Modern Google Ads accounts generally benefit from a consolidated structure rather than excessive micro-segmentation.
- Thematic grouping: Group closely related keywords by theme instead of creating separate ad groups for every keyword or match type. This keeps ads and landing pages relevant while giving Smart Bidding enough data to optimize effectively.
- Intent alignment: Build each ad group around one clear search intent, with keywords, ad copy, and landing pages addressing the same need. For example, keep transactional terms like “buy running shoes” separate from informational terms like “how to run faster”.
Avoid creating hundreds of small ad groups unless there is a clear business, messaging, landing-page, budget, or performance reason to separate them.
Keyword targeting
Review your keyword targeting to ensure it captures relevant searches and aligns with the audience’s intent.
- Match types and Smart Bidding: Evaluate whether Broad Match combined with Smart Bidding could expand reach without compromising CPA or ROAS. Avoid relying on exact and phrase match by default, but only broaden targeting when conversion tracking and campaign data are reliable.
- Negative keywords: Use negative keywords to exclude irrelevant searches and reduce wasted spend. Regularly review the Search Terms report to identify new exclusions without blocking valuable traffic.
- Keyword performance: Identify keywords generating irrelevant traffic, weak conversions, or inefficient costs. Pause, refine, or regroup them based on search intent, performance data, ad relevance, and business value.
Note: Negative keyword lists should not be treated as a one-time setup. Review search terms regularly, especially when using Broad Match or expanding campaign reach.
Bidding and Budget
- Bid strategy: Check the bid strategy you’re using for your campaigns and ad groups, such as manual CPC, enhanced CPC, target CPA, or target ROAS. Assess if it meets your goals; consider changing if needed. However, automation is recommended as it converts data faster and optimizes ad spending for better results.
- Bid adjustments: Analyze your bid adjustments for device, location, time of day, and audience. Ensure the adjustments align with your business objectives, such as increasing leads, sales, or website traffic. Moreover, review your competitors’ bidding strategies to adjust your strategy to remain competitive in the marketplace.
- Budget allocation: Check how your budget is allocated across campaigns and ad groups and whether it aligns with your business goals. Ensure all your money is used for ad groups with keywords that lead to conversions. Besides, you can divide your budget for different types of testing, such as A/B testing to find out which suits your campaign best.
Ad and Ad creative
Your ads are the final touchpoint that encourages users to click and visit your landing page. During the Google Ads audit, review whether your messaging and creative assets are relevant, compelling, and optimized across campaign types.
- Responsive Search Ads: Review Ad Strength and asset performance. Aim for 8–12 distinct headlines and up to four relevant descriptions, while avoiding repetitive messaging and unnecessary pinning.
- Performance Max asset groups: Check that each asset group includes relevant copy, high-quality images, and videos in multiple formats. Keep all assets aligned with the group’s theme, products, audience, and landing page.
- Ad assets: Ensure sitelinks, callouts, structured snippets, image assets, and other relevant assets are active, complete, and up to date. Replace weak or outdated content based on performance data.
4. Dig into Performance and Analytics
Performance metrics
When conducting a Google Ads audit, reviewing your performance metrics will help you get an overview of all campaigns as well as identify the areas that need adjustment. Here are some of the metrics that you have to pay attention to:
- Click-through rate (CTR): The percentage of people who click on your ad after seeing it. Google prefers ads with high relevance and CTR. To improve this, you must optimize your ad copy, image, CTA, and how it presents itself to the audience.
- Cost per click (CPC): The average cost of a click on your ad. Google will score your website low if you give your users outdated or poor-quality material, and your CPC will drop significantly. Additionally, improving your ad format and landing page will lower CPCs.
- Quality Score: A score assigned by Google to each of your keywords based on the relevance and quality of your ads and landing pages. To achieve this, ensure that your ad copy, keywords, and landing pages are all relevant to each other and the users’ search intent. Ensure that your landing page provides a positive user experience, and is optimized for mobile.
Conversions and Goals
Conversion goals assist you in organizing your conversion activities so that you may more quickly optimize toward your advertising goals. Therefore, constantly checking helps you better understand how everything is running.
- Conversion rate: The percentage of users who completed a desired action on your website after clicking on your ad. Across all industries, a “good” website conversion rate is between 2% and 5%. The conversion rate will go up if there are fewer distractions, such as new product selections, links, and irrelevant information.
- Return on ad spend (ROAS): The revenue generated for every dollar spent on advertising. A low ROAS can indicate that your targeting, bidding, or messaging needs improvement. Spending less on your ad while focusing on other factors is valuable.
Analyzing each campaign separately allows a marketer to identify which advertising is running effectively so that it can be extended to optimize results. Therefore, constantly checking on conversion rate and ROAS can help you archive your ad campaigns’ effectiveness.

How to check campaign success after Google Ads audit
After explaining the Google Ads audit process and its settings, remember that the audit itself doesn’t update the account or campaigns (unless there’s something urgent to fix). The important part comes after the inspection. A specific report is created for planning, roadmap, and process development to manage the account effectively. We also provide adjustments for optimizing your Google Ads audit process.
Check the search term report
The search term report plays a vital role in triggering your ad. Watch out for irrelevant search phrases that cost you money, and check search terms that receive plenty of clicks but few conversions.
Analyze data using Google Ads Preview and Diagnosis
Google Ads Preview and Diagnosis is a tool that allows you to see how your ads appear in different geographic locations and languages, as well as what search terms triggered them. Here are some ways to use this tool for a better Google Ads audit:
- Review ad position: Check the ad position and how it appears in the search results to identify if your ad is displaying correctly.
- Preview ads: Preview your ads to ensure that they show up correctly, adhere to the Google Ads text limit, and that the landing pages work correctly.
- Check search terms: Use the diagnosis tool to see what search terms are triggering your ads and make sure that they are relevant.
- Analyze ad auction insights: Analyze the auction insights report to get an idea of how you’re competing with other advertisers.
- Verify targeting: Check that your ads are targeted to the correct locations, languages, and devices.
Using the Google Ads Preview and Diagnosis tool, you can identify any issues with your ads and take corrective action to improve their performance. This tool is essential to any Google Ads audit, as it allows you to check ad positions, preview ads, analyze auction insights, and verify targeting.
Segment by device
On their phones, as opposed to PCs, people behave differently. When viewed on a computer versus a phone, your website appears differently. You will frequently notice that the performance of phones, tablets, and computers varies for other reasons.
Therefore, segment by the device to identify issues with your website’s performance on a certain device. If your mobile conversion rate is significantly lower than your computer conversion rate, then you should try to optimize the format on both devices. Furthermore, different devices will result in different conversions, which you can use to adjust your bids per device based on the data.
