When we audit a Google Ads account for the first time, we almost always find waste. Not a little waste. Often 30 to 50 percent of the monthly budget going on clicks that have no realistic chance of turning into customers. The frustrating thing is that the causes are almost always the same, and they are all fixable.
Here is a walk through the most common ways local businesses burn their Google Ads budget, and what a proper audit does to find and fix them.
Broad match keywords spending on junk
This is the single biggest source of wasted spend in most small business accounts. Broad match is Google's default keyword match type, and it casts a very wide net.
When you add a keyword like "accountant" on broad match, Google will show your ads for a huge range of searches it considers related. That might include "accountancy degree," "accountant salary," "how to become an accountant" and "free accounting software." None of those will ever become a client. But they each cost you money.
We have audited accounts where broad match keywords were responsible for over 60 percent of spend and less than 10 percent of the actual conversions. The fix is to switch your core commercial keywords to phrase match or exact match, where you have much more control over which searches trigger your ads.
No negative keyword list
Even with well-chosen match types, irrelevant searches will slip through. Negative keywords are the list of terms you tell Google never to show your ads for.
Most self-managed accounts have a sparse or nonexistent negative keyword list. That means budget goes on searches like "jobs," "apprentice," "DIY," "free," "how to" and any number of terms that indicate the searcher is not looking to buy.
Building a comprehensive negative keyword list is one of the highest-ROI tasks in Google Ads management. It does not cost money to add negatives. It just requires time, attention and the discipline to review your search terms report regularly.
For a trades business, obvious negatives include "jobs," "vacancy," "apprenticeship," "training," "salary," "courses" and any terms related to DIY repair. For a professional services firm, add "student," "degree," "template," "example," "free," and so on. Every industry has its own list.
Sending all traffic to the homepage
This is ubiquitous in accounts that were set up quickly without proper thought given to the user journey.
A potential customer searches for "emergency boiler repair Cheltenham," clicks your ad and lands on your homepage. The homepage talks about the full range of your heating services, has a generic headline and requires the user to navigate to find what they need. Most leave immediately.
The homepage is designed for people who already know your brand and want to explore. It is not designed to convert cold traffic from a specific search query. Ad traffic should go to landing pages that directly match the intent behind the search: specific, focused, with a clear headline that mirrors the search term and a single obvious next step.
Building dedicated landing pages takes work, but the improvement in conversion rate is usually dramatic. We regularly see conversion rates double or triple when traffic is moved from a homepage to a relevant landing page.
Not tracking conversions
This deserves repeating because it is so common and so damaging: if you are not tracking conversions, you are flying blind.
Without proper conversion tracking, Google has no idea which clicks lead to enquiries and which do not. This matters because Google's smart bidding strategies (Target CPA, Target ROAS, Maximise Conversions) learn from conversion data. If you are using these strategies without feeding them real conversion data, the system is making bidding decisions based on nothing meaningful.
It also means you cannot make good decisions yourself. You might have five campaigns running. Without conversion data, you do not know whether it is campaign three that is generating all your leads or campaign one. You cannot shift budget towards what is working because you do not know what is working.
Set up conversion tracking for phone calls from your ads (using Google's call forwarding), form submissions and any other meaningful action on your website. Do this before you do anything else.
Campaigns running 24/7 when your customers only search during certain hours
Many businesses receive enquiries primarily during working hours. A plumber takes calls between 7am and 7pm. A B2B professional services firm receives enquiries Monday to Friday. Running ads at 2am on a Sunday may simply be wasted budget.
Look at your conversion data by hour and day of week. If certain time windows produce clicks but no conversions, use ad scheduling to reduce bids or pause delivery during those periods. Your budget then concentrates on the times when people are actually likely to become customers.
Bidding on competitor brand terms without a clear strategy
Bidding on competitor names is a legitimate strategy but one that requires care. The click-through rates on competitor terms are often lower (the user was looking for someone else), quality scores can be poor and conversion rates are typically worse than on intent-based searches.
Unless you have a very specific reason to target competitor searches, the budget is usually better spent on keywords where the searcher is looking for a type of business rather than a specific business.
What a proper audit finds
A thorough Google Ads audit looks at all of the above and more: campaign structure, bidding strategy, quality scores, landing page relevance, audience targeting, budget pacing, impression share and geographic performance. It is a systematic review of every place where money can leak out.
The typical finding is not one big problem. It is a collection of smaller inefficiencies that compound each other. Fix the match types, build the negative keyword list, add conversion tracking and fix the landing pages, and you can often generate significantly more enquiries from the same budget.
