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
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 suspended6.7 millionadvertiser accounts and restricted4.3 billionads 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 thisultimate guide to PPC for lawyersto 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 lowQuality Scoresand, 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 toGoogle 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 theSearch 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.
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 highQuality 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 yourResponsive 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 show33%of UK marketing professionals have seen their Google Ads costs go up over the last 12 months, while23%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 candiscover more on UK digital marketing statisticsto 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.
