A Google Ads audit is not just a technical to-do list; it is a deep dive into your account to plug leaks, find growth opportunities, and stop wasting money. Think of it as a comprehensive health check, making sure your campaigns are structured smartly, targeting the right people, and actually measuring what matters.
Setting a Clear Foundation for Your Google Ads Audit
Before you even think about keywords or ad copy, a proper audit starts with a clear purpose. This is a strategic exercise, not just a box-ticking one. First, you need to get crystal clear on your primary business goals. Are you chasing leads? Driving online sales? Or trying to build brand awareness? Aligning the audit with what actually moves the needle for your business is non-negotiable.
This initial phase is all about setting a reliable benchmark. It involves a bit of housekeeping – checking administrative and security settings to make sure the data you are about to analyse is both accurate and secure.
To get started, here is a quick rundown of the essential checks that form the bedrock of any good audit.
Initial Audit Checklist
| Check Area | What to Look For | Why It Matters |
|---|---|---|
| Business Goals | Clearly defined objectives (e.g., leads, sales). | Aligns the audit with business success, not just vanity metrics. |
| Account Access | Unrecognised users, former employees or agencies. | Prevents unauthorised changes and protects your performance data. |
| Security | Two-step verification status for all users. | Adds a critical security layer against unauthorised account access. |
| Billing | Current payment methods, correct billing details. | Avoids unexpected ad pauses that disrupt campaigns and lose traffic. |
| Change History | Unexpected modifications, Google's auto-applied changes. | Ensures changes align with your strategy, not just automated suggestions. |
These foundational checks ensure that when you start digging into the data, you are working with a clean, secure, and accurate account.
Reviewing Account Access and Security
First, let’s see who has the keys. Go through the list of users with access to your account. It is good practice to remove permissions for old agencies or ex-employees. This simple task is your first line of defence, protecting your account from unauthorised changes and securing your valuable performance data.
While you are there, enable two-step verification for every user. This adds a crucial layer of security, making it significantly harder for anyone to get in, even if they somehow manage to get a password.
A secure account is the starting point for a trustworthy audit. Without it, you cannot be certain that the performance data you are looking at is a true reflection of your paid search activity.
Checking Billing and Change History
Nothing stops a high-performing campaign in its tracks faster than a failed payment. Double-check that your payment methods are up to date and all billing details are correct. Any slip-up here can cause your ads to stop running without warning, killing your momentum.
Next, head over to the change history log. This is your account's black box, recording every single modification. Look for anything that seems odd or automated, especially changes from Google’s auto-apply recommendations. While sometimes helpful, they can also make adjustments that contradict your strategic goals.
This review also helps keep you on the right side of compliance. For instance, a 2026 Competition and Markets Authority (CMA) investigation into Google's advertising services signals that regulators are watching closely. In 2022 alone, Google suspended 6.7 million advertiser accounts and restricted 4.3 billion ads for violations. A quick scan of your change history is a smart move to protect your account from compliance headaches.
Understanding the Fundamentals
Before diving deeper, it is worth having a solid grasp of core PPC principles. Some industries, like the legal sector, have incredibly specific advertising rules and compliance standards. To set a clear foundation for your audit, it can be helpful to review something like this ultimate guide to PPC for lawyers to appreciate the nuances of a well-executed campaign.
By starting with these foundational checks, you build a solid and secure base. From here, you can confidently move on to the rest of your audit, knowing that every pound you spend is more accountable.
How to Analyse Your Account Structure and Campaign Settings
A logical account structure is not just about keeping things tidy; it is the foundation of an effective Google Ads strategy. When we start any audit, this is one of the first places we look. A sensible structure gives you better control over your budget, makes performance analysis simpler, and has a direct impact on your Quality Scores.
The aim here is simple: organise your campaigns in a way that mirrors your business. This could mean structuring them by service line, product category, or even different customer personas. If you open your account and cannot immediately see how your budget is being spent or which campaign does what, it is a clear sign your structure needs work.
Evaluating Campaign Organisation
One of the most common issues we see is an account that has grown organically over time without a clear strategic plan. This almost always leads to messy ad groups stuffed with a random mix of unrelated keywords. The result? You are forced to write generic ads that try to speak to everyone but end up connecting with no one.
This lack of relevance is a primary cause of low Quality Scores and, in turn, higher ad costs.
A well-structured account, on the other hand, is built on tightly-themed ad groups. For example, a consultancy offering project management services might have separate campaigns for "Agile Training" and "PRINCE2 Certification". Digging deeper, the "Agile Training" campaign could be split into distinct ad groups for "Agile for Beginners" and "Advanced Agile Workshops," each with its own highly specific keywords and tailored ad copy.
This level of detail is crucial. It ensures your ads are highly relevant to what someone is searching for, which naturally improves click-through rates and signals to Google that your ads are a good match for user intent.
Auditing Core Campaign Settings
Beyond the high-level organisation, the individual campaign settings dictate where, when, and how your ads show up. These are often misconfigured, leading to a significant amount of wasted budget. During an audit, we focus on a few critical areas.
Location Targeting: Is your budget being spent in the right geographical areas? A local Essex-based business, for instance, has no reason to be showing ads to people in Scotland unless they serve customers nationally. Double-check that your targeting is precise and, just as importantly, that you are excluding areas you do not serve. We frequently find accounts targeting the entire UK by default – a costly mistake for most small businesses. You can get more tips on this in our guide to Google Ads for local businesses.
Ad Scheduling: Your ideal customers are not searching for your services 24/7. Dive into your performance data, breaking it down by day of the week and hour of the day to pinpoint when you get the most activity. If you are a B2B consultancy, you might notice that conversions drop over the weekend. A simple ad schedule lets you pause ads or lower bids during these quiet times, saving your budget for when it will have the most impact.
Device Targeting: People search differently depending on their device. Mobile searches are often for quick answers on the go, while someone on a desktop might be doing more in-depth research, ready to make a considered purchase. You need to review your performance across desktops, mobiles, and tablets. If you see that one device type is a consistent underperformer, you can apply a negative bid adjustment to spend less on it.
A common but easily fixable error is neglecting device-specific performance. If mobile users have a high bounce rate and a poor conversion rate, continuing to pour money into mobile ads without first investigating the user experience on your site is a missed opportunity for efficiency.
By methodically reviewing your campaign structure and its core settings, you start to take back control. This process uncovers the quick wins that can immediately stop wasted spend and boost performance. A clean, logical structure does not just make your account easier to manage; it makes it fundamentally more effective.
Reviewing Keywords, Ad Copy and Assets
This is where your strategy meets the audience. The connection between your keywords, your ads, and your audience is the entire point of a Google Ads account. A proper audit must dig deep into whether your keyword strategy and ad creative are working together to pull in the right people and convince them to act.
We are checking that your budget is being spent efficiently and your messaging is hitting the mark. This means getting into the details of your search query reports, picking apart your keyword match types, and analysing how well your headlines, descriptions, and other assets are performing.
Analysing Your Keyword Strategy
Your keywords are the front door to your audience, so you cannot afford to get them wrong. When we run an audit, we are hunting for keywords that are burning money on irrelevant clicks – one of the most common problems we find in accounts that have not been looked at for a while.
The first port of call is always the Search Query Report. This report is a goldmine. It shows you exactly what people typed into Google to trigger your ads, revealing whether your chosen keywords are attracting the right sort of traffic.
For instance, imagine you offer premium business coaching services, but your ads are showing up for searches like “free business advice”. That is a clear sign your match types are probably too broad, and you are throwing your budget at people who will never become qualified leads.
One of the quickest wins in any Google Ads audit comes from building a robust negative keyword list. By regularly reviewing search queries and adding irrelevant terms as negatives, you immediately stop wasting money and improve the quality of your traffic.
The Role of Keyword Match Types
Understanding keyword match types – and using them correctly – is fundamental to keeping your spending under control.
- Broad Match: This gives Google the most leeway, showing your ad for searches it considers related to your keyword. It can be a tool for finding new search terms, but it often leads to wasted spend if it is not managed with a smart bidding strategy and a hefty negative keyword list.
- Phrase Match: Your ad appears for searches that include the meaning of your keyword. It strikes a good balance between reach and control.
- Exact Match: This gives you the tightest control, showing your ad only for searches with the same meaning or intent as your keyword.
A classic mistake we see is relying too heavily on broad match without any of the necessary safety nets. This can drain your budget in no time, paying for clicks from people who are not looking for what you sell. A big part of the audit is checking that the match type strategy fits the campaign’s goals and budget.
Evaluating Ad Copy and Assets
Once your keywords are dialled in, the next job is to scrutinise your ad copy and creative assets. Your ads have to be relevant, compelling, and aligned with what the user was searching for. When we audit ads, we are looking for that tight alignment between the keyword, the ad headline, and the landing page content.
This "message match" is vital for achieving a high Quality Score. When you get it right, you are telling Google that your ad is an excellent answer to the user's query, which in turn can lead to lower costs per click and better ad positions.
We also have to analyse the performance of your Responsive Search Ads (RSAs). It is crucial to check the performance ratings for every single asset – both headlines and descriptions – and aim for "Good" or "Excellent." Any asset marked as "Poor" should be paused and replaced with a new variation. The idea is to give Google's system a strong pool of high-quality assets it can test and combine.
This process is more important than ever, as many businesses are struggling with rising costs and falling performance. In fact, recent reports show 33% of UK marketing professionals have seen their Google Ads costs go up over the last 12 months, while 23% have watched their click-through rates decline. A good audit directly tackles these issues by optimising keywords and ad copy to get performance back on track. You can discover more on UK digital marketing statistics to see how your own metrics stack up.
By meticulously reviewing every element from keyword to ad copy, you make sure your creative is working as hard as your budget. This is how you transform your campaigns from a simple broadcast tool into a highly effective machine for attracting your ideal customers.
Assessing Your Targeting, Bidding, and Budget Allocation
Effective targeting, bidding, and budgeting are the three pillars holding up your entire Google Ads account. Get them right, and your ad spend delivers real returns. Get them wrong, and you are just pouring money down the drain.
A proper audit needs to scrutinise each one. We check that your message is reaching the right people, that you are paying a sensible price for their attention, and that your cash is fuelling the campaigns that drive your business forward. Putting your budget behind the wrong audience or using a bidding strategy that is misaligned with your goals will burn through your resources faster than anything else.
Evaluating Your Audience Targeting
Your targeting settings decide who sees your ads. It is as simple as that. Nail this, and you connect with people actively searching for what you offer. Miss the mark, and you are just paying for clicks from an audience that will never convert. We often find accounts leaning too heavily on basic demographics, missing out on more valuable audience segments.
During an audit, we dig deeper than just age and gender. We assess how you are using more specific audience types:
- In-Market Segments: Are you targeting users Google has flagged as actively researching or planning to buy products like yours? These audiences are gold for driving conversions.
- Affinity Audiences: These are broader, interest-based groups. While less direct, they can be great for building brand awareness, especially if you have a longer sales cycle.
- Remarketing Lists: You must be re-engaging with past website visitors. It is crucial to segment these lists properly. For instance, someone who abandoned a shopping basket should be treated very differently from someone who just read a blog post.
- Customer Match: Are you using your own first-party data? Uploading a list of existing customers allows you to re-engage them or create lookalike audiences to find new people with similar traits.
A classic mistake many businesses make is failing to exclude past converters from their acquisition campaigns. It is a small oversight, but it means you are spending money to acquire customers you already have. This is a simple fix that immediately makes your budget work harder.
Auditing Your Bidding Strategy
Your bidding strategy is your instruction to Google on how much you are willing to pay for a click or a conversion. There is no single "best" option here; the right choice hinges on your campaign goals, how much conversion data you have, and the level of control you want to keep.
A common issue we see is a blind reliance on Smart Bidding strategies like Target CPA or Maximise Conversions, without giving the algorithm enough quality data to work with. These automated strategies need a healthy volume of conversions – we always suggest at least 30 conversions in the last 30 days – to learn and optimise effectively. If you do not have that volume, a manual approach like Enhanced CPC could give you better control and better results.
Your audit should be asking:
- Is the chosen bid strategy aligned with the campaign’s objective (e.g., leads, sales, visibility)?
- Does the campaign have enough conversion data to make an automated strategy work?
- Are you A/B testing different bid strategies to see what performs best?
This analysis is more important now than ever. In the first half of 2025, UK businesses invested £8.3 billion in search advertising. With 65% of advertisers now using AI for optimisation, it is vital to ensure these automated systems are working for you, not against you. A small efficiency gain of just 5-10% can mean reclaiming thousands in monthly spend. You can discover more insights about UK advertising trends at PPC Chief.
Analysing Budget Allocation
Finally, let's follow the money. A Google Ads audit must review how your budget is spread across your campaigns. It is rare for all campaigns to perform equally, yet many accounts have budgets that are set once and then forgotten about.
The goal is to shift funds based on performance. Pinpoint your top-performing campaigns – the ones with a strong return on ad spend (ROAS) or a low cost per acquisition (CPA) – and make sure they are not being held back by a limited budget. On the flip side, campaigns that are struggling need to be investigated or have their budgets reined in.
Always look for campaigns that are consistently “limited by budget.” If these are your star performers, you are leaving valuable conversions on the table. This simple check ensures your investment flows to the areas that will grow your business.
Validating Your Conversion Tracking and Analytics
If your data is wrong, you are just guessing with your budget. That is why any Google Ads audit worth its salt must get deep into your conversion tracking and analytics. If your tracking is off, you cannot trust your performance data, which makes smart decisions on budget, bidding, or creative impossible.
Your conversion data is the one true benchmark for what is working. It is the proof a startup needs to show investors, or what a charity relies on to report its fundraising impact. Getting this right means every pound you spend can be properly accounted for.
Confirming Your Conversion Actions
First, we need to look at what you are measuring. Your account should only track actions that have genuine business value. This could be a completed sale, a submitted lead form, or a phone call from a potential new client.
We often see accounts where "conversions" include low-value actions like page views or time on site. While these metrics can give you a feel for engagement, classing them as primary conversions will seriously distort your data. This does not just mislead you; it also sends Google’s automated bidding strategies off in the wrong direction, optimising for useless outcomes.
A proper audit makes sure every conversion action is:
- Correctly categorised (e.g., as a ‘Lead’ or ‘Purchase’).
- Assigned an appropriate value, which is vital for calculating return on ad spend (ROAS).
- Set as a ‘Primary’ or ‘Secondary’ action to correctly inform your bidding strategies.
One of the most common tracking mistakes we find is multiple tags firing for a single action, creating duplicate conversions. This inflates your numbers, makes campaigns look more successful than they are, and tricks automated bidding into overspending.
Checking the Technical Setup
Once you have nailed what you are tracking, you need to check how you are tracking it. This means digging into the technical implementation to spot those quiet, background problems that can break your data collection without you noticing. A simple website update or a plugin change can be all it takes to stop a tag from firing.
During a Google Ads audit, we methodically check the links between your website, Google Ads, and Google Analytics 4. A clean, solid connection here is essential for getting a complete picture of the customer journey. You can learn more about how all these moving parts fit together in our guide on how to measure marketing ROI.
Common Conversion Tracking Issues and Fixes
Finding and fixing tracking issues is fundamental to restoring the integrity of your data. Here is a quick rundown of the frequent problems we come across and how you can get them sorted.
| Common Issue | How to Identify It | How to Fix It |
|---|---|---|
| Duplicate Conversions | Check the ‘Conversions’ column for unusually high rates or numbers that look too good to be true. | Use Google Tag Assistant to simulate a conversion and see if multiple tags fire. Remove any redundant tags. |
| Broken Tracking After a Site Update | Notice a sudden, sharp drop in reported conversions that does not align with your traffic levels. | Manually test all conversion actions on your website (e.g., fill out a form). You may need to re-implement the tracking code. |
| Inconsistent Data with GA4 | See major discrepancies between the conversion numbers reported in Google Ads and those in Google Analytics 4. | Ensure GA4 goals are imported correctly into Google Ads. Check you are not double-counting by using both GA4 and native Ads tags for the same event. |
| No Value Assigned to Conversions | The 'Conversion Value' column is empty, which stops you from being able to calculate your ROAS. | Edit your conversion actions to assign a static value for leads or implement dynamic value tracking for e-commerce sales. |
Verifying your tracking is one of the most critical parts of an audit. Accurate data gives you the confidence to invest your budget wisely and prove the real-world impact of your campaigns.
Creating Your Action Plan and Measuring Success
An audit that just sits in a folder gathering dust is a waste of everyone's time. The real work begins after you have gathered all your findings. Now, it is about turning those insights into a practical, prioritised plan that transforms your audit from a report into a roadmap for growth.
The key is to move from analysis to action without getting bogged down. With a structured approach, you can focus on what matters most, notch up some quick wins, and then methodically plan for the bigger changes that will pay off in the long run.
Prioritising Your Findings
First, you need to sort through everything you have uncovered. I find the most effective way to do this is to score each issue against two simple criteria: potential impact and required effort. This exercise quickly separates the easy fixes from the major strategic projects.
For instance, adding a handful of negative keywords to block irrelevant clicks is a classic low-effort, high-impact task. On the other hand, a full account restructure is a high-effort undertaking, but it could change your performance for the better.
An audit’s true value is unlocked when you prioritise effectively. By focusing on high-impact, low-effort tasks first, you can build momentum and demonstrate immediate value, which helps secure buy-in for more complex changes down the line.
Once you have scored everything, your findings should fall neatly into a clear action list:
- Quick Wins (High Impact, Low Effort): These are your top priorities. Jump on them immediately to stop wasting budget. Think of things like pausing bleeding ad groups, fixing broken sitelinks, or adding an obvious negative keyword list.
- Major Projects (High Impact, High Effort): These are your big-ticket items, like overhauling campaign structures or re-implementing conversion tracking from scratch. They need proper planning, so map them out with clear steps and realistic timelines.
- Fill-in Tasks (Low Impact, Low Effort): These are the smaller tweaks that are good to get done but will not revolutionise your account overnight. This could include tidying up ad group naming conventions or adding a few new ad assets to start testing.
- Re-evaluate Later (Low Impact, High Effort): If a task demands a huge amount of work for a tiny return, it is usually best to park it. You need to stay focused on the actions that will move the needle.
Building Your Remediation Roadmap
With your priorities straight, it is time to build a simple remediation roadmap. This document turns your to-do list into a project plan. For every action item, you should clearly define the task, assign it to a specific person, and set a firm deadline.
This step is all about creating clarity and accountability. It makes sure everyone knows who is doing what and by when, preventing those audit insights from getting lost in the daily grind.
Trustworthy data is the bedrock of any good Google Ads account. This flowchart breaks down the core validation process.
Moving from checking your setup to confirming its value shows how a methodical approach helps you trust your results.
Measuring Success and Continuous Improvement
A great audit is never a one-off job. It should be the starting pistol for a cycle of continuous improvement. Once you have started implementing your fixes, you must measure their effect on your key performance indicators (KPIs). Did your cost per acquisition (CPA) drop? Has your return on ad spend (ROAS) climbed?
Get a regular review schedule in the diary. I recommend a light monthly check-in on the core metrics, followed by a deeper dive every quarter. This approach turns the audit from a reactive firefighting exercise into a proactive process of ongoing optimisation. A detailed paid search analysis can give you a solid framework for these regular reviews.
By embedding this cycle of auditing, acting, and measuring into your marketing, you ensure your Google Ads account stays healthy, efficient, and aligned with your business goals.
Frequently Asked Questions About Google Ads Audits
We get asked a lot about the audit process. Here are a few of the most common queries that land in our inbox, along with our direct answers.
How Often Should I Conduct a Google Ads Audit?
For most accounts, a deep-dive audit once a year is a solid baseline. It gives you a thorough, top-to-bottom health check.
However, if you are managing a larger budget or you are up against stiff competition, we would suggest a lighter review every quarter. Markets shift, new competitors appear, and what worked last season might not work now. Staying on top of it this frequently prevents small issues from becoming big, expensive problems.
Can I Perform a Google Ads Audit Myself?
Absolutely. With a comprehensive guide like this, you can run your own audit. It is a great way to get familiar with your account's inner workings.
That said, there is value in a fresh pair of eyes. When you are in the account every day, it is easy to miss the forest for the trees. An experienced strategist can spot underlying issues you have become blind to. If a significant chunk of your business relies on Google Ads, that outside perspective is often worth its weight in gold.
What Is the Most Common Issue Found in an Audit?
Hands down, the most frequent and costly mistake we uncover is wasted budget.
This almost always traces back to a few core problems: a messy campaign structure, using the wrong keyword match types, or a non-existent negative keyword list. The result is always the same – you end up paying for irrelevant clicks from people who were never going to convert in the first place.
